This COA was extracted from a community forum attachment. The original poster claimed a lab tested HB Peptide's Retatrutide, reporting 99.873% purity and a quantity of 20.50 mg for a 20mg label. The test is recent (under 3 months). However, the lab's signature is not directly verifiable, and there is a chain-of-custody gap, so this should be treated as community signal, not confirmation.

Watch out for
  • chain-of-custody gap
  • unknown lab
  • no endotoxin test
