Very impressed with the CoA
Documentation is what sold me. Independent CoA per batch, clean HPLC traces. Reconstitution behaved exactly as expected. Solid supplier for research use.

About this compound
Melanotan I
Linear α-MSH analogue
Melanotan I (afamelanotide) is a linear α-MSH analogue with higher potency and stability than the native hormone, developed at the University of Arizona. It is a selective reference agonist for the MC1 receptor.
MC1R agonism is studied in vitro for eumelanin-pathway and cAMP signalling in melanocyte models.

Melanotan I is a linear α-melanocyte-stimulating-hormone (α-MSH) analogue known as Melanotan I, supplied by MyPeptides for laboratory research use only.
Melanotan I is a linear α-melanocyte-stimulating-hormone (α-MSH) analogue known as Melanotan I. MyPeptides supplies it as a lyophilised 10 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Melanotan I in melanogenesis and melanocortin-receptor research. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Melanotan I order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. Linear structure, distinct from cyclic Melanotan II — useful for comparative binding studies.

Trust these guys
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.

Consistent batch to batch
Support answered a batch question within a few hours over email. Rare to get that level of response from a research supplier. Product itself is exactly to spec.
