TB-500 99.2% Purity — HomopeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Homopeptide's TB-500, showing 99.193% purity and a quantity of 5.09mg (1.8% over label). However, the lab's signature is not directly verifiable, and the test is stale (over a year old). This should be treated as community signal, not confirmation.
