Melanotan II is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH). PubChem lists its molecular formula as C50H69N15O9, with a molecular weight of about 1024.2 g/mol. Its cyclic lactam structure makes it a widely referenced melanocortin-receptor research peptide.

KYVEC supplies Melanotan II as a lyophilised (freeze-dried) powder in a sealed, labelled vial, packed in our signature KYVEC black box. Each label shows the product name and quantity, so stock can be logged and tracked in your lab inventory as soon as it arrives.

Storage and handling: Store unopened vials in a cool, dry place away from light. For long-term storage, refrigerate (2–8°C) or freeze (−20°C). Once reconstituted for laboratory use, keep refrigerated and avoid repeated freeze–thaw cycles. Handle with standard laboratory PPE.
