Alternatives to Truepeptidelabs in the UK: sellers you can actually verify
Truepeptidelabs (truepeptidelabs.com) 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 Truepeptidelabs is on the watch list
Truepeptidelabs markets its stock with the line 'third-party HPLC and LC-MS testing and lot-specific Certificates of Analysis'. Nothing is published up front: the certificate behind 'HPLC testing' is promised on request rather than shown, from a lab that is never named. An assurance designed to arrive only after the sale is not something a buyer can test in advance.
- Why it is on the watch list: 'COA on request', nothing published
- Trustpilot: 4.2 from 50 reviews, which reflects delivery and service, not what is in the vial
