TB-500 99.8% Purity — HM PEPTIDECertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested HM Peptide's TB-500, showing 99.771% purity via HPLC and a quantity of 5.41mg (8.2% over label). However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share. This should be treated as community signal, not confirmation.
