Beyond the literature: here's what third-party Certificate-of-Analysis records (Janoshik, BCC, Auxlabs) say about real Dulaglutide and Semaglutide batches we've tested. Aggregate, public data — cross-reference against the studies below.
Fewer than 3 published Dulaglutide COA records so far — not enough for a meaningful purity aggregate yet.
We tested 2418 Semaglutide batches across 608 manufacturers, 99.66% avg purity.
