Overview
About Melanotan I.
Melanotan I is a linear 13-residue α-MSH analogue in which methionine-4 is replaced by norleucine and L-phenylalanine-7 by D-phenylalanine, giving greater metabolic stability than native α-MSH. In research settings it acts as a non-selective melanocortin receptor agonist, with activity at MC1R associated with stimulation of melanogenesis (eumelanin synthesis).

FAQ
Melanotan I — frequently asked by B2B buyers.
Is Melanotan I the same as Melanotan II?
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.
What documentation ships with each lot?
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 (only if specifically ordered and tested) testing, can be provided for qualified B2B accounts.
What purity and format do you supply?
Melanotan I is supplied as a white-to-off-white lyophilized powder, typically ≥99% by HPLC. Standard catalog format is 10 mg per vial; alternative fills and bulk quantities are quoted on RFQ.
What are the MOQ and private-label options?
Catalog MOQ is 1 kit (10 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.
How is the product handled for compliance?
Material is sold strictly for research and manufacturing use, labeled for research use only, and is not offered for consumer or veterinary consumption or as a finished consumer product. Buyers are responsible for confirming the regulatory status and permitted uses in their destination market.
