Retatrutide 99.3% Purity — Top PeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested TOP's retatrutide, reporting 99.308% purity and a quantity of 55.93mg for a 50mg label (11.86% over). However, the lab's signature is not directly verifiable from this source, as the image has passed through at least one re-share. This should be treated as community signal, not confirmation.
