FAQ
No. Melanotan I is afamelanotide (NDP-α-MSH), a linear 13-amino-acid α-MSH analogue, CAS 75921-69-6. Melanotan II is a shorter cyclic 7-amino-acid analogue with a different CAS and molecular formula. They are chemically distinct compounds and are catalogued separately.
Every lot is supplied with a Certificate of Analysis showing HPLC purity, mass-spec identity confirmation, appearance, and peptide/water content. TDS, and on request additional data such as residual solvent or endotoxin testing, can be provided for qualified B2B accounts.
Melanotan I is supplied as a white-to-off-white lyophilized powder, typically ≥98% by HPLC. Standard catalog format is 10 mg per vial; alternative fills and bulk quantities are quoted on RFQ.
Catalog MOQ is 50 vials of the 10 mg format. We support OEM / private-label programs including custom vial fills, labeling, and packaging; lead times and tiered pricing scale with order volume and are confirmed at quotation.
Material is sold strictly for research and manufacturing use, labeled for research use only, and is not offered for human or veterinary consumption or as a finished consumer product. Buyers are responsible for confirming the regulatory status and permitted uses in their destination market.
