## What we are and what we are not

We are an independent UK peptide research and assessment platform. We do not sell, dispense, prescribe, recommend specific products to specific people, or run promotional copy for prescription medicines. When a reader is ready to buy or consult, links route to UK retailers, MHRA-licensed pharmacies, and CQC-registered clinics where appropriate.

We are not regulated by the FCA (UK consumer credit rules are not in scope). We are not regulated by the MHRA as a pharmacy or wholesaler. We are not registered with the GMC or CQC as a clinical provider. We hold no license to sell prescription medicines. We hold no license to advise on personal treatment.

Where UK regulatory rules apply to advertising, we follow them: ASA CAP code on cosmetic and collagen claims; MHRA rules on prescription-only medicine advertising; UK research-tier MHRA enforcement on lab-use peptides being kept distinct from consumer routes.

## Categories

### Cosmetic peptides

Topical skincare peptides marketed for visible-skin claims. Includes Matrixyl variants, copper peptides (GHK-Cu), Argireline, and similar. UK regulatory route: cosmetics, with ASA CAP code applying to claims. Editorial comparison covers UK retailers, ingredient transparency, dose, clinical evidence quality, and price.

### Ingestible collagen

Oral collagen supplements: hydrolysed marine, hydrolysed bovine, and vegan precursor products. Comparison covers source, dose, evidence quality, price per gram of collagen, and UK retailer availability. Specific subjects: women in menopause (oestrogen-collagen interplay), athletes (recovery context), age-banded use.

### Research peptides

Lab-use chemicals. Examples covered editorially: BPC-157, TB-500, Tesamorelin, GHK-Cu, MOTS-c, Epitalon, Sermorelin, Melanotan. These are sold for research use only in the UK. They are not licensed medicines, they are not for human use, and consumer sale into the human-use channel is enforced against by MHRA. Our editorial is descriptive: what each is, what it is studied for in published preclinical or clinical work, and the regulatory reality of buying it. We do not link to sellers who target consumers, we do not publish dosing for human use, and we do not run testimonial copy.

For Melanotan specifically we publish no UK retailer links given the documented MHRA risk position.

### GLP-1 weight-loss routes

Prescription weight-loss medicines: Wegovy (semaglutide), Mounjaro (tirzepatide), and related. UK access routes covered: NHS specialist weight-management referral, ICB rollout state, private prescription via CQC-registered clinics, and MHRA-licensed online pharmacies. Editorial covers eligibility (BMI thresholds, comorbidities), supply state, side-effect profile, aftercare, and clinic comparison.

We do not prescribe. We do not run paid placements for clinics. Clinic listings are comparison-tier, ranked by methodology criteria (eligibility transparency, named prescriber, GMC and CQC status, supply reliability, aftercare offer).

## Methodology summary

Listicles and comparison pages score each entry against intent-weighted criteria. Each "best for" page publishes its weights at the foot of the page so readers can see what drove the ranking.

Common cross-category criteria:
1. Source transparency (who supplies, where, traceable)
2. Dose disclosure (per serving, per gram, per millilitre)
3. Evidence quality (peer-reviewed work cited, not testimonials)
4. UK availability (in-stock, ships UK, paid in GBP)
5. Price per active unit
6. Customer track record (UK Trustpilot weighted to last 12 months)

GLP-1 clinic-specific criteria add: prescriber named on site, CQC registration verified, supply route disclosed (MHRA-licensed pharmacy), aftercare programme, side-effect monitoring, refund/withdrawal policy.

Re-test cadence: every six months minimum, sooner on product withdrawal, formulation change, MHRA action, supply interruption, or material customer complaints flow.

## Flagship reference tool: the PeptideClear Trust Index

https://peptideclear.co.uk/coa-trust-index/ is independent, free assessment of UK research-peptide retailers on the same principle as Which? Trusted Traders or Checkatrade: a fixed, published checklist applied to every seller we can identify. This is not a customer-review or third-party star-rating pull-through (no Trustpilot or similar aggregation). PeptideClear does publish its own mechanically-derived, per-retailer editorial Review/rating structured data, authored by the PeptideClear editorial team and computed identically from the same published checklist for every retailer: a genuine editorial review, not a crowd-sourced one. Sellers do not apply to be included, and no seller pays to be included or for a better baseline result.

Retailers are assessed against three baseline pillars:

1. Testing Transparency, six observable signals: per-batch CoA publishing, gating method (open / email / login / image / absent), third-party laboratory partner naming, QR-verifiable batch lookup, dedicated CoA URL, and stance on third-party testing.
2. Business Transparency: UK Companies House trading-entity confirmation. A retailer whose UK entity is dissolved, or cannot be found, is capped accordingly regardless of Testing Transparency score.
3. Responsible Practice: whether marketing and product claims are clear, fair and not misleading, on a four-tier scale (Clear and responsible / Generally responsible / Unclear / Material concerns), plus a fifth Baseline review pending state for a signal awaiting re-confirmation.

As of this writing: 274 UK retailers identified, 159 assessed; see the live page for current counts, updated on a rolling basis. 115 could not be assessed at all (dead domain, blocked, too new, or closed) and are excluded from the baseline rather than marked negatively.

On top of the free baseline, PeptideClear offers a separate paid tier, Independent Verification: 54 checks across 8 areas, technology-assisted research plus targeted deeper checks and manual/editorial review, with a formal right of reply for potentially material findings before publication. The free baseline does not carry a formal pre-publication right of reply: an ordinary observable baseline change publishes without contacting the retailer, and only a potentially material baseline finding goes to manual review before publishing. Independent Verification is invoiced through LionCrownX Ltd, a commercial entity separate from PeptideClear's editorial and publishing operation; PeptideClear itself does not receive that payment, and payment cannot buy a better baseline result, a positive verification outcome, or baseline inclusion. The assessment is deliberately narrow throughout: it measures testing transparency, business transparency and responsible marketing practice, not overall product safety or efficacy.

The underlying Testing Transparency dataset is also published read-only under CC BY 4.0 at https://peptideclear.co.uk/data/api/ (REST API + MCP server), OpenAPI spec at https://peptideclear.co.uk/openapi.json.

## Editorial standards

- No paid review placements.
- No paid ranking position.
- No AI-generated reviews without the editorial team signing them off.
- Every category page and listicle carries a date line from its logged publication and content-update record, plus an editorial team byline. A "Last reviewed" date appears only where an editorial review has been logged.
- Material changes get logged in a short footer note.
- Outbound links carry rel="nofollow" and earn this site nothing. The category prefers retailers that hold MHRA, CQC, or recognised cosmetic safety standards over those that do not.
- No dosing guidance for research peptides. No human-use dose tables.
- No GLP-1 prescription advice. We route readers to qualified prescribers.

## Disclosures

PeptideClear takes no commission, referral fee or listing payment from the retailers, clinics, pharmacies or brands it writes about, and no payment can buy a better placement or result. Outbound links carry no tracking and earn the site nothing. There is no sponsored slot inventory and no paid placement of any kind. This changed on 19 July 2026, when all affiliate arrangements were removed; before that date the site did earn affiliate commission. Separately, UK research-peptide retailers can pay for the work of PeptideClear's Independent Verification process (see above); that payment is invoiced through LionCrownX Ltd, not received by PeptideClear's editorial operation, and cannot buy a better baseline result or a positive verification outcome. See https://peptideclear.co.uk/how-we-are-funded/.

We do not buy, sell, or trade prescription medicines. We do not hold or dispense prescription stock.

## Geography and audience

UK adults researching peptide categories. The site assumes UK retail context, GBP pricing, UK shipping, UK regulatory framework, and the UK GLP-1 access landscape (NHS specialist weight-management referral and ICB rollout state, private clinic comparison).
