Alternatives to Gb Peptides in the UK: sellers you can actually verify
Gb Peptides (gb-peptides.co.uk) does not publish a certificate of analysis you can verify in its own name. If that is why you are looking for an alternative, the UK sellers further down do, so you can check the testing yourself before you buy. The Peptide Watch takes no vendor money and links to no seller's shop.
Why Gb Peptides is on the watch list
The Gb Peptides site claims '>=99% purity (verified by HPLC) Third-party lab tested with full Certificates of Analysis available upon request'. Behind 'HPLC testing' there is no named laboratory and no certificate you can pull up, so a buyer is asked to take the number on trust. A purity number a buyer cannot trace back to a laboratory is marketing, not evidence.
- Why it is on the watch list: No named lab, nothing to verify
- Trustpilot: 4.0 from 4 reviews, which reflects delivery and service, not what is in the vial
- Pricing: BPC-157 at £3.00/mg, at the market median across the sellers we track, so price tells you nothing here; the testing gap is the whole difference
