Research peptide retailer
Peptide Labs UK
Lab not named
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.

Separate from the CoA score
Responsible Practice assessment
Material concerns- · About page carries live unfilled placeholder text.
- · Sells products under codenames (MAZX1, CAGX) rather than the compound's real name, in a site category literally called 'Fat Loss', with clinical-trial weight-loss percentages quoted on the product pages.
We assess what a brand publishes and makes available to customers, not its intentions. Full framework and what each status means: how we assess brands. Think this is wrong? Email [email protected] with evidence.
Not yet Independently Verified
The CoA tier and Responsible Practice status above are free and mechanical. Nobody, including Peptide Labs UK, has paid for the deeper lab-accreditation, batch-traceability, and corporate-history checks yet. Request that it be run →
Best for
Researchers wanting GLP-1-adjacent compounds (Tirzepatide, Retatrutide, Mazdutide) inside a broader peptide catalogue, plus an adjacent biomarker blood-test service.
Weak on
CoA gated behind email request rather than openly published. Newer trading history than UKPeptides or Pure Peptides UK.
What stands out
- · Fat Loss category leads the navigation (Tirzepatide, Retatrutide, Mazdutide)
- · Above 99 percent HPLC and mass-spec verified purity claim
- · Long-form pillar guides with named author (William) and PubMed citations
- · Adjacent biomarker blood-test service (50+ markers)
- · Member-only pricing tier on account creation
- · Activist-style email signup (push for government action on counterfeits)

Our verdict
The only major UK research-peptide retailer leaning explicitly into Tirzepatide and Retatrutide. CoA email-gate is the conversion mechanic but reduces transparency vs Pure Peptides UK.
