Retatrutide 99.3% Purity — QianyecaoCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Qianyecao's Retatrutide, reporting 99.292% purity via LCMS and a 5.15% quantity overage (21.03mg tested vs 20mg label). However, the lab's signature is not directly verifiable, and the image has passed through at least one re-share, creating a chain-of-custody gap. This test is also stale (over 1 year old).
