AOD-9604 is a short synthetic peptide — about sixteen building blocks — that copies a tail-end fragment of human growth hormone, with one extra building block added at the front.
Each batch ships as one consistent lot and goes to an outside lab for its certificate of analysis, which is posted to the verification page and found by lot number.
What sets this record apart is how carefully its internal loop was confirmed: a small bridge folds part of the chain back on itself, and that closure was read directly from the compound's published structure rather than copied from a supplier sheet. It is the kind of detail a reference standard should verify rather than assume.
