UK retailer reviews
Editorial reviews of the UK clinics, pharmacies and research peptide suppliers we link to. Each profile covers price, regulation, what they are best for, what they are weak on, and our verdict. Every outbound link is untracked; PeptideClear earns nothing when readers click through.

Research peptide retailer
Per peptide, varies
my-peptides
UK research peptide retailer with HPLC-verified purity claims and CoAs included on orders. Operates under research-use-only framing.
BPC-157 5mg £13.99, TB-500 5mg £36
Pure Peptides UK
Long-established UK research peptide supplier. 12 years trading, 15,000+ customers. Operates a public CoA subdomain (coa.purepeptidesuk.com) with downloadable per-batch certificates linked from every PDP. Dual-tier purity (Standard vs Premium with endotoxin LAL + heavy-metal testing on Premium).
BPC-157 5mg from £13.00 at 100+
UK Peptides
14 years trading from Middlesbrough. The deepest classic-peptide plus Russian-bioregulator catalogue in the UK (Bronchogen, Cartalax, Pinealon, Thymalin, Vilon, Crystagen). Open volume-tier pricing on every PDP with rotating monthly site-wide promo. Publishes a contrarian manifesto rejecting third-party CoAs as forgery-prone in favour of in-house LCMS/HPLC (commissioned 2026 to 2027).
BPC-157 £17.99, Tirzepatide from £42.99
Peptide Labs UK
Anti-counterfeit-framed UK research peptide retailer leaning hard on Fat Loss as primary nav category (Tirzepatide, Retatrutide, Mazdutide) alongside the broader catalogue. Above 99 percent HPLC and mass-spec verified purity claim. CoA gated by email request. Long-form pillar guides with named author byline and PubMed citations.
Wolverine Stack £29.99, BPC-157 single from £14.99
XL Peptides
Nottingham-based research peptide retailer (Bio Research Ltd, since 2024). Bundles and stacks are the hero SKU (Wolverine BPC-157 + TB-500, Tesamorelin + Ipamorelin 3:1, KLOW, Glow). Janoshik third-party CoAs published per batch with QR-code verification. 10-vial bulk packs alongside singles. Wholesale tier above 11 vials.
BPC-157 from £18.99, Wolverine Stack discounted
Dr Peptides
Family-run Newcastle research peptide retailer (Rian, Victoria, Leah Redman). Owner-fronted WhatsApp on every page. CoAs photographed into the product gallery (COA in image) rather than gated. Heavy on named-stack bundles (Wolverine, Hulk, Ultimate Bundle). Crisp live chat sitewide. Personal accountability is the trust play.
Per peptide, varies
Tide Labs
UK research peptide retailer leaning on UKAS-verified HPLC as the sole-in-UK trust claim. Narrower catalogue than UKPeptides or Pure Peptides UK but the lab-verification angle is the loudest in the segment.
Per peptide, varies
Imperial Peptides
UK research peptide retailer with third-party HPLC plus transparent batch documentation. Plays the credibility lane alongside Pure Peptides UK and Tide Labs.
Per peptide, varies
Peptides UK
Long-trading UK research peptide retailer (2012). Heavy on classic compounds (BPC-157, TB-500, GHK-Cu, CJC-1295, Ipamorelin, MOTS-c). No GLP-1, no cosmetic line. CoA gated via on-site contact form (request lab report per product). Reconstitution calculator on-site.
GLP-Semaglutide £80 to £220 per vial
Peptagenix
UK research peptide retailer (Peptagenix UK Ltd, October 2024). Lead category is GLP-1 / Semaglutide. Inline reconstitution dose calculator on homepage. Mail-forwarding Covent Garden address. Athlete-facing framing alongside scientists and labs.
Anglo Peptides
Established London research-peptide retailer (Anglo-Peptides Ltd) with HPLC/MS testing, RUO framing and a strong Trustpilot footprint.
Bluewell Peptides
UK CoA-verified research-peptide supplier trading since 2022 with >=99.1% HPLC claims and a Trustpilot profile.
£4.99 to £220
Chroma Peptides
UK research-peptide retailer with per-batch HPLC and independent CoAs and explicit RUO framing across a broad catalogue.
£3.99 to £79.99

OP Labs
Established London research-peptide supplier (formerly Oxford Peptides, RFR Global Ltd) with >=99% HPLC batch COAs and strict RUO framing.
£9.99 to £69.99
Thoroughbred Labs
Established UK research-peptide retailer (since 2022) with HPLC >=99%, a CoA page, clear RUO framing and a registered UK entity.
Alpha Peptides
Brand-new entity (incorporated 21 Jul 2026, Chatham virtual-office). Publishes downloadable 'research verification reports' citing Janoshik but these are company-authored summaries not raw per-batch reports with lot numbers/QR. Bank-transfer-only checkout. Product copy softly implies tissue-repair benefits despite RUO framing.
Aura Peptides
No downloadable/verifiable CoA system, only vague 'we can provide COAs' FAQ line. No lab named, no UK company registration disclosed. Checkout/support mainly via WhatsApp/Telegram and a gmail.com contact address.
Biohack Peptides
Publishes genuine third-party Janoshik HPLC certs via direct lab-hosted verification links, clear RUO disclaimers per product. But no UK company registration disclosed anywhere (Privacy Policy/Terms have unfilled '[Insert Company Name]' placeholders), and uses benefit-style language (BPC-157 'accelerating recovery from injury').
BioLab Peptides
Claims per-batch CoAs and HPLC/MS testing but CoAs must be requested by email, no lab named, claims UK registration but discloses no company number/address and no matching CH entity found. 5-Amino-1MQ capsule product carries direct fat-loss benefit claim on the one page lacking a RUO disclaimer.
Blue Peak Peptides
Trades on-site as 'BluePeak' not 'Blue Peak Peptides'. Names credible lab (Janoshik) with lot-specific CoA claims but gated behind email request, 'verify on Janoshik' link is a non-functional placeholder. Own Terms page lists HQ as Hong Kong despite claiming England & Wales jurisdiction - no matching UK CH entity.
Bodylab
Clear RUO disclaimers sitewide, but CoA claims inconsistent (image-only 'test report' on some product pages, absent on others), no named lab, no batch/QR verification. Registered address (5 Brayford Square, London E1 0SG) is documented shared registered-office/mail-forwarding address, no matching CH entity found.
Bonafide Peptides
No CoA process of any kind, no named lab, no company registration/address, no findable Trustpilot. Unlike every other retailer in this batch, could not confirm ANY research-use-only disclaimer at all despite being a live functioning storefront.
Buy Retatrutide
Claims UK-based (England & Wales law) but discloses no company name/number/address anywhere. CoA is a single static image, no batch-level/QR verification, no named lab. No CH or Trustpilot match found.
BuyReta
Explicit purity/lab-testing claims ('HPLC Verified','every batch independently lab-tested') but no dedicated CoA page anywhere, no lab named, no UK company registration disclosed, no card payment option (bank-transfer/crypto only).
Elixer Peptides
CoAs published openly per batch, but the UK company (15301118) was dissolved 24 Sep 2024 while the shop keeps trading; on-site 'business number' does not match any valid CH format.
GB Peptides
CoAs vague 'on request', no named lab; likely CH match (17136088) is a virtual office with active strike-off proposal, doesn't match Trustpilot's Coventry trading address.
Global Peptides
Batch CoAs by email/WhatsApp only, explicitly no QR/batch-verification; CoA contact address is on a different domain than the shop; no UK company registration disclosed.
Kensington Labs
Strongest CoA practice in this batch: dedicated CoA page links each peptide directly to Janoshik's own verification URLs, no login/request needed. But no UK company registration number disclosed anywhere on site.
Labgrade Peptides
Sitewide RUO disclaimer but no CoA/lab-testing practice found anywhere; no company registration shown; live-chat widget labels operator 'LGP INC', inconsistent with 'UK-based supplier' framing.
Nova Peptide
CoAs 'requested at checkout or contact page', tested by own 'compounding lab' not a named independent lab; no UK company registration shown; self-contradictory founding claim on about page.
Nupex
Real active UK company (16181281) and clear RUO disclaimer, but CoA hedged 'where available' with no named lab, and sells 13 oral capsule products with benefit language (muscle recovery, gut health, brain health) contradicting research-only/non-oral framing.
Peak Peptides
Homepage FAQ claims every batch is covered by a CoA, but no CoA link, document, or named lab appears anywhere on the shop or product pages, a claimed practice with no visible instance.
Peptide Supplies
RUO disclaimer present but no named lab, no downloadable/batch CoA; no UK company number disclosed; BPC-157 listing uses therapeutic language ('regenerative effects','promotes healing') despite RUO framing.
Peptides 4U
Domain redirects to rebrand 'P4U Wellbeing Ltd' (CH 17051612, itself under active strike-off proposal) sharing exact registered address of original dissolved Peptides4U Ltd (CH 16727596, dissolved 27 Jan 2026) - undisclosed dissolved-entity-continuity. Otherwise clean per-batch Janoshik CoAs, no company number/phone/address disclosed on-site.
Peptides of London
Static non-downloadable image thumbnails of certs, no named lab, no batch numbers, no QR verification. Registered address is mass virtual-office (Great Portland Street) shared by thousands; no CH entity confidently matched.
Phoenix Biolabs
Open per-batch CoAs hosted directly on Janoshik's own verification platform with unique batch codes; clear RUO disclaimers. But sells oral tablet/capsule formats despite RUO framing, and no UK company registration found despite UK-styled storefront.
Precision Peptides
Sells peptides/SARMs/injectable steroids alongside oral capsules; names 'Analiza Labs' but no downloadable/per-batch CoA, only on-request; registered at mass virtual office; MK-677 listing makes borderline benefit claim.
Precision Research UK
CoAs only via email after purchase, unnamed lab, never shown with batch number/QR. Product copy (BPC-157 'accelerated blood flow recovery') edges into benefit-implying language. Bank-transfer-only checkout.
Pretty Peptide
CoAs vaguely 'on request', no named lab, advertised QR 'Batch Check' portal not confirmed functional; no matching UK company found; Glow Stack listing language edges toward beauty-benefit claims despite RUO.
Pro Peptides Plus
UK storefront (GBP, UK shipping) but own T&Cs say governed by Nevis law; no matching UK CH entity; Shelton Street Covent Garden address is known mass company-formation/virtual-office address; CoAs are undated unbatched JPGs, no named lab.
ProLab Peptides
'COA Included/Batch-matched every order' badge and per-order batch codes but never a downloadable CoA/image/QR. No lab named beyond generic HPLC/MS claims. Operates from mass company-formation address (Shelton Street) shared by 1000+ firms, no confirmed CH match.
R&D Peptides
Per-batch CoAs but only 'on request' via generic contact form, no download/QR/named lab. No CH number, address or founding year disclosed despite thorough in-vitro disclaimers and live Trustpilot.
Sculpt Peptide
Own domain 301-redirects to sculptgb.co.uk, which claims 'thorough third-party testing' but publishes no actual CoA document/image/request process, no lab named, no company registration or address disclosed, no Trustpilot found.
Tested Peptides
Site largely unfinished build ('Pardon our dust'), only generic '>99% HPLC-tested' claim, no CoA, no named lab, no company registration anywhere; own Trustpilot reviews report company unable to provide batch info when asked.
The Peptide Code
Genuine batch-ID CoA lookup tool, no login/email gate, real active CH registration (17107501) - but incorporated only 21 Mar 2026 (under 5 months old). No specific lab named despite claiming ISO/IEC 17025 accreditation.
Trident Peptides
Claims generic HPLC/MS-UPLC batch testing and GMP manufacturing but no CoA document/batch number/QR anywhere. No company registration or address, no email contact (only login-gated 'secure message'). RUO disclaimer only on terms page. Product copy leans into benefit framing (PT-141 tied to sexual function, NAD+ 'MUST HAVE').
Union Biolabs
Names real third-party lab (Janoshik), 'each order includes a Certificate of Analysis' - but only sent with order, not downloadable/QR-verifiable before purchase. No company registration published. Contact address is a PO-box-style mailbox unit (Poole BH15 9EL), not trading premises.
Wholesale Peptides
Claims 'lab tested' and founding in 2012, but no CoA process, lab name, or Companies House match found anywhere on site.
Wild Ginger Peptides
Batch CoAs sent with order, strong RUO disclaimers, but testing only 'in-house', no named lab, no QR CoA, no CH match found.
Adonis Elite Peptides
CoAs only on-request, no named lab; own GHK-CU page pairs RUO disclaimer with benefit language ('anti-aging','wound healing'); footer CH number resolves to misspelled 'RESEARCH CORPERATION LTD'.
Bio Hack London
Strongest CoA setup in batch, independently verifiable on janoshik.com/verify. Companies House lists the registered office for this entity (incorporated 13 Nov 2025) as York, not London as the brand name suggests; we have not independently confirmed whether that reflects where the business actually operates versus a registered-agent address, so this is noted as a discrepancy to verify, not a settled fact.
Bio Peptides UK
~45 downloadable CoA PDFs, but named tester 'Analiza Bialek' reads as generic Polish phrase for 'protein analysis' not a clear lab brand - treat with caution.
Bionik Peptides
Names Janoshik but claimed CoA-on-product-page didn't hold up on checked product; registered at mass-formation Covent Garden address; products grouped by human-benefit categories ('Fat Loss','Anti-Aging') despite RUO framing.
C&D Peptides
Genuine young UK company (30 Sept 2025), but CoA page claims certificates downloadable from product pages when none could actually be found.
CoreLabs Peptides
NAME MISMATCH: domain actually trades as 'CoreLabs Peptides'/'CoreLab Supplies', not 'Core Peptides' (unrelated US brand corepeptides.net). Incorporated 7 Jan 2026 at mass-formation address; Testing page 'Coming Soon'.
Genetic Research
Open no-login CoA PDFs per product on dedicated HPLC Testing page; lab 'Analiza' visible in filenames but never named in prose; same filename pattern per product line suggests not genuinely per-batch. Registered at 124 City Road EC1V 2NX, mass virtual-office (~6000 companies). Sells a 'Capsule Research' line despite RUO framing.
Natty Peptides
Does NOT publish own CoAs. Runs an 'Independent Quality Assurance Guarantee' reimbursing customers who pay to test products themselves (Janoshik/Amino Asylum named as examples), refunds if purity fails - a real but different mechanism to a CoA library, scored as no disclosed CoA practice. Sells NMN/marine-collagen (oral) alongside injectables.
BPC-157 from £16.85
New Wave Peptides
UK research peptide supplier trading as New Wave Solutions Limited, listing 99%+ HPLC purity and per-batch lab reports across repair, GH-secretagogue and longevity ranges. Research-use-only framing runs throughout the site.
Peptides Clinic
No CoA/lab-testing/quality page exists anywhere in site nav. Generic 'Research use only' line on homepage but no company registration, payment or founding details published. CH shows entity (17044088) incorporated only 19 Feb 2026.
Platinum Peptides
Dedicated /pages/coas names no lab, vague 'made available for researchers to review' framing, no working download links actually rendering. Operating company renamed 'Platinum Peptides Ltd' -> 'Platinum Science Ltd' in April 2026 while storefront still trades as 'Platinum Peptides'. Registered at 124 City Road EC1V 2NX - SAME mass virtual-office address as Genetic Research in this batch.
Power Peptides
Dedicated CoA/Lab Reports page with batch-number filter claims every batch published, but currently shows 'No COA files available yet'. No lab named. Same-named CH entity (17201282) exists but wrong SIC code, not treated as confirmed match.
Per peptide, varies
Proforma Peptides
UK research peptide retailer trading as PFP Research Limited, with a public batch-numbered lab analysis library covering 70+ products and stated UK service hours six days a week.
Raccoon Peptides
Registered at confirmed virtual-office/mail-forwarding address (Wood Street E17). 'COAs' nav link and Trustpilot mentions of 'full COAs' but no actual access mechanism found. Retatrutide page carries RUO disclaimer directly alongside explicit benefit claims ('Faster, more dramatic fat loss', weight-loss %, 'wound healing').
Per peptide, varies
Regen Labs
UK-based research peptide retailer trading as Midshire Labs Ltd, with a recovery and longevity focused range, 99%+ purity claims and a public bank of per-batch third-party test reports. All products are framed as research use only.
Regenix Peptides
Test reports openly published, no login, each with unique verification key + QR linking to real janoshik.com/verify portal. Clean RUO disclaimer, no benefit claims. Checkout is bank-transfer/Pay-by-Bank only, no card.
RP Peptides
Trades via Wellcore Innovations Ltd (CH 14504852, formerly 'Luxe Tanning Ltd' renamed Aug 2024). CoA PDFs openly downloadable but product-level not batch-specific, no lab named. Site's own contact page cites a DIFFERENT company number (16405928) that is a dormant shell at the same address, not the actual trading entity. Only contact channels: WhatsApp + proton.me email.
Simply Peptides
Trades via Research Stack Ltd (CH 16843184) at Shelton Street Covent Garden, a well-known high-volume company-formation/virtual-office address. Lab Reports page is strongest of batch: real batch/lot numbers, mostly-working Janoshik QR verify links, second named lab too - but 3 older reports have broken QR codes, some newer reports password-protected. Trustpilot claim (4+ stars) could not be confirmed, page returned 403.
Vionex Peptides
Registered office matches real active company (Vionex Ltd, CH 16691739) though trading name is a variant not exact CH match. CoA Library shows batch/lot+purity as on-page entries not PDFs, no lab named, no QR. 5-Amino-1MQ page carries RUO disclaimer directly alongside animal-study benefit language ('reversed diet-induced obesity in mice') next to buy button.
Lucid Peptides
Open, no-login batch-number lookup returns a dated per-batch HPLC/LC-MS result, but it checks against Lucid's own internal records, not a named third-party lab's portal.
Essential Peptides
Dated per-batch CoAs are openly listed at /coas with a QR-code claim of third-party verification, but the QR/View-COA links resolve to Essential's own site and no lab is ever named.
Premier Peptides
The /certificate/ page shows only generic product-image mockups with no batch numbers, dates, or named lab, and this retailer sells oral capsule SKUs (NMN, 5-Amino-1MQ, SLU-PP332).
Ultra Peptides
Product pages promise a CoA 'available on our Lab Reports page' citing unnamed 'accredited laboratories', but that page 404s and no actual certificate instance could be found, while descriptions attribute tissue-repair/regeneration effects to the compound.
Revive Peptides
No CoA, lab-testing evidence, or third-party verification practice appears anywhere on the site, despite product pages carrying an RUO disclaimer alongside direct tissue-healing/anti-inflammatory claims.
Elevate Peptides UK
No CoA program is disclosed anywhere on the site, only a vague homepage claim that products are 'batch-tested for purity, stability, and consistency'; the JS-rendered shop consistently failed to load so individual product listings could not be verified.
Black Country Peptides
Homepage banner repeatedly claims 'THIRD-PARTY TESTED' with '99.9% purity' but no lab name, CoA document, QR code, or lab-reports page exists anywhere on the site to substantiate the claim.
Crown Peptides
Every bottle is said to carry a QR code and dated CoA reachable via an open, no-login peptide selector on their own /lab-reports/ page, but the QR resolves to Crown's own website (not an independent lab portal) and no specific lab is ever named, only 'HPLC and MS' methods cited.
Tru Form Peptides
Site makes a single passing claim of '3rd party testing' on the homepage but has no CoA document, no named lab, and no dedicated testing/quality page anywhere to substantiate it.
Benchmark Peptides
Runs a genuine searchable per-batch CoA database naming Janoshik as the testing lab with dated batch-specific purity results, but each certificate resolves only to a JPG image hosted on Benchmark's own server with no link to Janoshik's own verification portal.
Fusion X Peptides
About Us claims 'every product undergoes third-party testing' but no CoA document, named lab, or access point exists anywhere on site; RUO wording is confined to the Legal Notice page and absent from product pages carrying claims like 'enhances fat loss' and 'clinically validated'.
Future Peptides
Homepage claims '99%+ pure, backed by independent testing' but names no lab and no CoA page/document was found anywhere (quality page 404s); RUO disclaimer confirmed sitewide in footer.
Sussex Peptides / East Sussex Peptides
Redirects to eastsussexpeptides.co.uk; no CoA, lab name, or testing documentation found anywhere on the site, and the RUO disclaimer is buried mid-page in an 'Our Commitment' section rather than on individual product listings.
Surrey Peptides
No CoA, lab report, or named third-party lab found anywhere on the site despite a consistently-applied per-product RUO disclaimer; product descriptions use benefit-adjacent language ('weight-management outcomes', 'collagen production, skin renewal').
Nexus Peptides
'COA's' appears as an unlinked label in the site header but no actual certificate, document, or page exists anywhere (dedicated CoA and quality-assurance URLs both 404); RUO disclaimer is applied per-product.
RAW Peptides
No CoA, lab-testing page, or named third-party lab found anywhere on the site; only a generic sitewide RUO entry-gate disclaimer, no capsule/oral products found among the SKUs listed.
Neovia Peptides
Names Janoshik Analytical and links a dedicated /certificates page, but each CoA is served as a static per-product PNG image filed by SKU (not batch number), not the 'downloadable PDF certificates' the homepage claims, with no QR code or link to janoshik.com's own verification portal.
Opti Peptides
No CoA, lab-report page, or named lab found anywhere, only a vague 'thorough testing' claim, while the shop sells a capsule-form product (GHK-Cu Capsules) alongside a blanket research-only disclaimer on every listing.
Amino Peptides
Claims per-batch testing and CoAs but names no lab, and the dedicated /coas/ page shows no actual certificates: text there says to contact support to request the most recent testing data, no visible document instance or QR/lookup tool.
Pioneer Research Peptides
States '100% batches third-party tested' and 'COA included' but the certificate is only physically supplied with the order, no named lab, no dedicated online CoA page, and no QR/batch-lookup verification.
NXT Gen Peptides
Publicly viewable /lab-reports table shows real dated batch numbers for two products (most others 'pending release'), but the PDF certificate links are non-functional placeholders and the /verify batch tool checks NXT Gen's own site rather than a named third-party lab's own portal.
GH Peptides
No CoA, lab-testing, or quality-verification page or claim exists anywhere on the site; listings like 'Regenerative Energy and Anti Aging Blend' carry explicit benefit claims ('boosts collagen and elastin', 'fights fatigue') despite the research-only framing.
Peptides UK 4U
Per-batch, dated CoAs are freely downloadable PDFs with a batch-number lookup tool, but they are hosted on the retailer's own storage rather than linking to the named lab's own portal, so third-party verification cannot be independently confirmed.
The Peptide Company
Dedicated lab-reports page freely lists batch ID, date and purity per product, open no login, but no named third-party lab and no downloadable certificate file found.
UK Peptide Lab
Each product page links an openly downloadable dated per-batch CoA PDF naming a real lab, self-hosted on the retailer's own domain rather than verifiable on the lab's own portal.
British Peptides
Homepage states 99%+ HPLC Purity, COA Available on request but no downloadable link or named lab found; MK-677 and Tesofensine tablets sold alongside injectable vials.
UK-Peptide
No CoA or third-party lab language appears anywhere; product page pairs a research-use disclaimer with consumer-style benefit copy; MK-677, KPV and Tesofensine sold as tablets.
LeoLab
Each product links a per-item 3rd Party Test Report page but it's only a screenshot PNG with no lab named, BPC-157 product page carries no RUO disclaimer and makes direct benefit claims.
Synergetics
FAQ states CoAs available upon request with no visible instance or named lab, product bundles marketed under consumer-benefit names despite an RUO disclaimer in Terms of Service.
Midshire Labs
CoA page hosts 13 dated Test Report files but each is a plain PNG screenshot, no specific third-party lab ever named despite repeated third-party-tested language.
Prestige Peptides
Every product page carries a Self Verify widget linking to the real janoshik.com/verify/ portal, but Task Number and Unique Key fields are blank on every product checked, batch documentation described as available on request.
NXT Peptides
Markets COA Verified and a Lab Certificate Lookup tool, but the production JS bundle reveals the actual UI renders a literal placeholder reading Lab certificate document to be placed here, no real lab named.
Peptides Pharmacy
Dedicated CoA page is educational only, states customers can ask for available COA documents before ordering, no lab named, no RUO disclaimer found.
Astra Labs
Per-batch CoAs openly listed by batch code and date, self-branded Janoshik Verification Hub linking to verify.janoshik.com, no login required.
BuyRetaUK
CoA page shows only a labelled Sample table, no specific lab named beyond independent UK laboratories, no verification link.
RETA UK
Searchable CoA table lists batch IDs, test dates and purity with View Certificate links for direct cross-check at janoshik.com/verify.
UK SARMs
Batch-specific PDF certificates from two named US labs (MZ Bio Labs, Colmaric Analyticals) are openly linked from a dedicated purity-certificates page and individual product pages, but there is no QR/lab-portal cross-check and product pages carry explicit benefit claims (e.g. Enhanced Muscle Growth, Fat Loss) despite research-only wording.
UK Peptides (ukpeptides.com)
Homepage claims certificates of analysis available for all products and independent HPLC analysis on every batch but names no lab and links to no actual CoA document; site became bot-protected on repeat fetch attempts.
UK Peptides (.is)
Separate WordPress build carrying the same UK Peptides branding as ukpeptides.com; a testimonial states COA provided with every order but no lab is named and no CoA page or QR verification exists.
UK Peptide Store
No CoA, lab-testing, or quality-verification page exists anywhere, no third-party lab is named, only a general research-use homepage claim.
UK Peptide Supply
No CoA/lab-testing content exists anywhere on the site; only a homepage-level research-purposes-only banner, not repeated on individual product pages.
PeptideLabUK
Dedicated Certificates of Analysis page is a policy statement, not a document repository, with zero actual certificate links and no lab ever named.
Verified Peptides
Per-batch, dated CoAs are freely viewable with product pages linking directly to janoshik.com test-result pages, though certificate images are also mirrored on-site; verifiedpeptides.co.uk is a separate placeholder, not the live retailer.
Peptide Supply UK
Marketing copy states COA included with each order and testing by unnamed independent UK laboratories, but no CoA documents, lab name, or verification link are published anywhere; the footer Lab Testing link is a dead placeholder.
TrimFast
Site states batches are independently tested with certificates available on request, but no lab is named and no CoA document or page is published anywhere.
DN Lab Research
Advertises 3rd Party Tested and FDA-registered cGMP labs as taglines but has no dedicated lab-testing page, names no lab, publishes no CoA; sells oral capsule peptides carrying benefit language, RUO disclaimer confined to a popup not the product listing.
Receptor Chems
Product pages say CoAs are available upon request with no downloadable document found, About page attributes testing to their own facility rather than an external lab.
MuscleChem
No CoA, lab-testing, or verification page exists anywhere despite active sale of tablet-form BPC-157 with explicit healing claims on the product page.
Particle Peptides
Per-batch dated CoA PDFs openly published in a public COA Vault with no gate, but lab never named, no QR/lookup verifying against any lab's own portal.
Peptide Barn
No CoA, batch number, or lab report disclosed anywhere, though every product page carries its own research-only disclaimer.
Beyond Peptides
Per-batch dated CoAs openly linked from a central lab-reports page and product pages, name Janoshik Analytical, include a direct verify link to their own portal.
Prime Peptides
Per-batch dated CoAs with batch numbers freely viewable on a testing page and repeated on each product page, each with a direct verify link into verify.janoshik.com's own portal.
PharmaLabGlobal UK
CoAs are freely downloadable per-product PDFs signed by Janoshik with a QR/key verifiable at janoshik.com/verify, but the certificate's own Batch field reads Unknown and product pages carry explicit benefit claims with no research-only disclaimer of their own.
Peptide Systems
Per-batch lot-specific CoAs from an ISO 17025-accredited lab are directly downloadable PDFs linked openly with no login gate, but no QR/lab-portal cross-verification and catalog limited to two SKUs.
Research Peptide
Claims batch-specific CoAs at 99%+ HPLC purity but every mention is gated behind available-on-request language with no lab named, no visible certificate; product pages carry RUO disclaimers alongside explicit therapeutic benefit claims.
Peptide Works
CoAs are freely downloadable PDFs, lab-tested by Janoshik with a QR code verifiable at janoshik.com/verify/, but the certificate's own Batch field is left blank so it reads as one representative test per product rather than a true per-batch document.
Peptora Labs
Per-batch CoAs with lot numbers sit behind a simple age/researcher self-certification click-through, naming Elementrix Laboratories, though whether the lookup resolves to the lab's own portal could not be confirmed.
Pure Lab Peptides
Every order ships with a physical COA card verified via a one-time code on the retailer's own verify page, no third-party lab named.
HCS Pharma
Functions as a review/comparison site rather than a direct retailer, Buy Now redirects to leolab.co.uk, no CoA, no lab, no RUO disclaimer, explicit health claims.
Euro-Gen Peptides
Now 301-redirects entirely to expresspeptides.co.uk, confirming same operator Prism Industries Ltd, FAQ admits third-party CoAs not currently issued.
The Peptides Outlet
Confirmed wholesale reseller carrying 13 third-party label brands, CoA practice inconsistent, some as gallery images, others none.
My Reta
Fully live with a public CoA page listing per-batch certificates linking directly to Janoshik Analytical's own verification portal.
Peptiology
peptiology.co.uk redirects to peptiology.com, confirmed same operator, per-batch CoA system but testing is by Peptiology itself (Dubai), effectively in-house.
Peptology Labs
Per-batch CoAs verified via batch number lookup directly on janoshik.com, open access, RUO disclaimer in footer not on product listings.
Alphamino
Each product page embeds a static screenshot labelled a Janoshik report, not a live link, lab named but CoA not independently verifiable.
Apex Biolab
FAQ claims downloadable CoA on every product page but none found; testing lab is unnamed German lab under NDA, reports not publicly available.
Bio Pulse Labs
Batch test results available on request with no named lab, shop categories market under outcome labels like Anti-aging and Weight Management.
BIOLABS
No CoA, lab-testing page, named lab, or RUO disclaimer found anywhere; catalogue includes oral capsule items.
Just SARMS
Sells capsule-form peptides with a per-product RUO disclaimer, but no CoA, lab-testing page, or named third-party lab exists anywhere, benefit-framed shop categories in product navigation.
Revive Peptides EU
Claims cGMP/ISO9001 in-house HPLC testing but publishes no actual CoA, names no third-party lab, no CoA page in navigation.
Reta Supplier
Per-batch purity cards under vague European labs branding, no lab named, most Available on Request, one Download CoA PDF link resolves to a blank PDF; site claims products approved for human therapeutic use, contradicting RUO framing entirely.
Reta Research
Open batch-list CoA page naming Janoshik Analytical and Analiza Bialek as independent labs, View COA opens an actual report screenshot with QR code checkable at janoshik.com/verify, delivered as an image not a native PDF.
Retatrutide UK
Each batch has its own COA that must be requested by email, naming only a generic independent lab, homepage separately brands the product a weight-loss treatment.
Pepturion
Per-batch Janoshik test reports with QR code and verify-at-janoshik.com key are freely viewable via a View CoA modal, but served as a PNG image rather than a linked document.
The Peptide Lab UK
No CoA, lab claim, lab name, or research-use disclaimer appears anywhere; catalogue mixes misspelled peptides with unrelated anabolic steroids under an Oral category.
BioLabs Peptides / BioFlex Peptides
biolabspeptides.com has a per-product COA tab linking a batch-specific Freedom Diagnostics report as an image; sibling bioflexpeptides.com claims every batch is tested but shows no actual CoA and sells an oral-capsule product. mybiolabshop.com no longer shares an operator with these -- it now redirects to biolabshop.co.uk, an unrelated already-separately-listed general supplements storefront, so the three-way same-operator premise did not hold on re-check.
Astra Peptides / Astra Labs Research
Homepage names Janoshik Analytical and claims every batch is tested, but no CoA link, download, or dedicated lab-results page exists anywhere (all checked paths 404); TB-500 product page carries explicit consumer benefit claims directly above its RUO disclaimer.
LeoLabs UK / LeoLab UK
Original domain no longer resolves; the live LeoLab UK site claims validation by third-party lab testing but names no lab, no CoA page, pairs RUO disclaimer with explicit weight-loss/healing benefit claims.

DTS Pharmacy / Global Pen Peptide
dtspharmacy.com and globalpenpeptide.com run identical Shopify navigation and copy consistent with common ownership; neither has any CoA or lab-testing page, both 404, product pages carry aggressive health-benefit claims beside the RUO disclaimer.

CoA page explains a batch may have a certificate if available but customers must email to request it, on-request model with no lab named and no visible certificate instance.
Peak Research Co
Dedicated certificates page openly lists per-product CoA headers with no login wall, but names no specific lab and shows no batch dates or QR verification; product page combines RUO disclaimer with explicit benefit claims.
Ascend Peptides UK
Live, functioning retailer with an open (no-gate) CoA archive of 12+ batch-specific certificates, each linking directly to janoshik.com test pages that redirect to verify.janoshik.com, confirming this is Janoshik's own third-party portal.
