The UK peptide quality index
We independently score every UK retailer and clinic on lab transparency, certificate-of-analysis evidence and company standing. See who’s verified before you spend a penny.
Sample cards · the live index also lists Amber and Red-graded suppliers — we publish the fails too.
Pick GLP-1, research peptides, cosmetic or a clinic. We surface the suppliers that scored highest on transparency for that category.
Each supplier is graded A–E on six checkable signals: per-batch CoA, named lab, QR lookup, dedicated URL, age-gating, Companies House standing.
Compare verified prices, check stock, or get matched to an MHRA/CQC-vetted UK clinic — only ever to suppliers that passed.
GLP-1 weight-loss
A 60-second check against UK prescribing criteria. If you’re suitable, we introduce you to a CQC-registered clinic from the Trust Index — never a grey-market seller.
