How the CoA Trust Index works

01 · RUN

Tell us what you want

Pick GLP-1, research peptides, cosmetic or a clinic. We surface the suppliers that scored highest on transparency for that category.

02 · SEE WHO PASSED

Read the score, not the marketing

Each supplier is graded A–E on six checkable signals: per-batch CoA, named lab, QR lookup, dedicated URL, age-gating, Companies House standing.

03 · GET INTRODUCED

Go to a verified supplier

Compare verified prices, check stock, or get matched to an MHRA/CQC-vetted UK clinic — only ever to suppliers that passed.

Info, not advice

PeptideClear is an independent UK editorial comparison and introducer service. We do not sell, dispense or prescribe. GLP-1 weight-loss medicines are prescription-only and supplied only after assessment by a qualified prescriber. We may be paid by suppliers we introduce you to; this never changes how we score.
