Beyond the literature: here's what third-party Certificate-of-Analysis records (Janoshik, BCC, Auxlabs) say about real Melanotan II and PT-141 batches we've tested. Aggregate, public data — cross-reference against the studies below.
We tested 1419 Melanotan II batches across 590 manufacturers, 99.68% avg purity.
We tested 1400 PT-141 batches across 535 manufacturers, 99.73% avg purity.
We hold deeper lab coverage on Melanotan II (1419 batches tested). PT-141 edges ahead on average measured purity (99.68% vs 99.73%) — a narrow gap; weigh it against failed-batch and underdose counts above.
Studies in our corpus that mention both Melanotan II and PT-141 — the gold-standard direct comparison evidence.
