Entry 0026 · Rev 1.0 · Reviewed 2 Nov 2026

Melanotan II is a cyclic seven-residue analogue of alpha-MSH made at the University of Arizona in 1989. It acts on several melanocortin receptors. Its human data are three small studies from the 1990s; it is not licensed anywhere, and UK regulators have warned against unlicensed tanning products containing it.

FAQ

Before you order

Which lot will I receive?

The lot shown in the buy box. It is printed on your vial label, and the same number opens its certificate in the lot register.

What is in the vial?

Melanotan II as a dry, white powder sealed under a crimped cap. Nothing else is added.

When will my order arrive?

UK orders paid before 3 pm on a working day leave the same day by Royal Mail Tracked 24, free, and usually arrive the next working day. EU orders take 3 to 5 working days; the US and Canada 5 to 7.

Is Melanotan II for human use?

No. Melanotan II is sold as a research material for laboratory use only. It is not a medicine and is not for human or veterinary use. The library entry describes what published studies measured, not how to use it.

How do multi-buy discounts work?

Order 3 or more vials of the same product and size for 10% off each, or 5 or more for 15% off. The discount shows in the basket straight away.
