Retatrutide 99.2% Purity — GYCCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum, where the original poster claimed 'Peptide Test' analyzed GYC's Retatrutide (batch GB #10 Red Cap). The reported purity was 99.183% and quantity was 15.35mg (2.33% over label). However, the lab's signature is not directly verifiable from this source, and the test is stale (over 1 year old). This should be treated as community signal, not confirmation.
