Alternatives to Wgpeptides in the UK: sellers you can actually verify

Wgpeptides (wgpeptides.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 Wgpeptides is on the watch list

Wgpeptides tells buyers '99%+ purity, third-party tested with Certificates of Analysis'. Behind 'third-party tested' 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: 4.4 from 10 reviews, which reflects delivery and service, not what is in the vial
