Melanotan 1 UK — buying guide

Melanotan I, known by the research designation afamelanotide, is a linear synthetic analogue of the endogenous peptide alpha-melanocyte-stimulating hormone (alpha-MSH). It carries CAS number 75921-69-6 and a molecular weight of 1646.85, and is noted in the literature for its selectivity toward the melanocortin-1 receptor (MC1R).

In the research literature Melanotan I is studied in models of melanogenesis and pigmentation biology, where investigators explore the biochemistry of melanin-related signalling. Sova provides it strictly as a characterised reference material — an MHRA-sensitive pigmentation compound with no claim of any physiological or human effect made or implied by its supply.

Melanotan I (linear, MC1R-selective) is distinct from the cyclic Melanotan II, and they are easily confused, so a mass-spec result tied to the batch is the check that confirms which one you have.

Every Sova Melanotan I vial ships with a batch-linked Certificate of Analysis. Before you buy, confirm the CoA references the batch on the vial, that identity is confirmed by ESI mass spectrometry against the expected 1646.85 Da, and that purity is measured by reverse-phase HPLC. Enter the batch at /verify to pull the certificate.
