Most people buy from a UK peptide retailer on the strength of the retailer's own claims. PeptideClear checks the evidence first: what a business can actually prove about its testing, its identity and its conduct, not what it says about itself.
The UK reference
Independent transparency assessments of UK research-peptide retailers, built from what each business publishes and what the public record shows. Nobody is charged to be included, and nobody can pay for a better result.

How retailers are assessed
A retailer can do well on one and poorly on another; nothing here is averaged into a single letter or number.
Per-batch certificate of analysis, from a named third-party lab, checkable against the lab's own records.
Whether a matching UK trading entity can be confirmed on the public record. A gap is a fact we couldn't establish, not wrongdoing.
Whether a retailer's site and marketing hold to its "research use only" positioning, checked against a published standard.
Independent Verification
Undertaken on request, published either way: a structured, 8-area digital evidence assessment that goes well beyond the free baseline.
Independently verified
54 checks · 8 areas
Lab authenticity, batch and report traceability, corporate reality, regulatory footprint, catalogue and legality, business conduct, and a claims/marketing audit. Payment buys the labour of running the checks, not the result.
One UK retailer has completed it so far: Ascend Peptides UK, verified 18 August 2026. Its baseline results are unchanged by verification.
Search & AI visibility
of PeptideClear's traffic arrives already trying to work out whether a specific peptide supplier can be trusted — reviews, comparisons and “is this retailer legitimate” research, not general browsing.
Google Search Console data, PeptideClear analysis, current as of August 2026. “AI reads” counts confirmed fetches by AI crawlers (GPTBot, ClaudeBot, PerplexityBot and others): it shows AI systems retrieving PeptideClear's pages, not that a specific AI answer named PeptideClear.

Editor's desk
What the approval covers, who it applies to, and what it changes for the wider GLP-1 market.
How to verify a certificate of analysis yourself, not just take our score on trust.
What changed in the 21 August Trust Index refresh, and why.
Independence
PeptideClear does not sell peptides, dispense medication or prescribe. Nobody pays to be listed or scored in the baseline Trust Index, and nobody can pay for a better result. Independent Verification is a paid service, commissioned and invoiced separately from PeptideClear's editorial work: the fee buys the labour of running the checks, not the outcome.
