Research background

About Melanotan II

Melanotan II (MT-II) is a lactam-bridged cyclic peptide derived from alpha-melanocyte-stimulating hormone (α-MSH), designed at the University of Arizona. Unlike the natural hormone it is not selective: it acts at several melanocortin receptors, including MC1R on pigment cells and MC4R in the brain.

That broad receptor profile makes MT-II a reference agonist in melanocortin and pigmentation research. The literature includes early human pharmacology (Dorr et al., 1996) and reports of harm after unsupervised use (Brennan et al., 2015; Paurobally et al., 2011). Medabol supplies it for laboratory research only, in Skin, hair & pigment next to Melanotan I.

Melanotan II FAQ

How is Melanotan II different from Melanotan I?

Melanotan I (afamelanotide) is a linear analogue of α-MSH; Melanotan II is a shorter, cyclic one with a broader receptor profile. They have different CAS numbers and molecular weights, so compare the two product pages before ordering.

What does the COA confirm for a cyclic peptide?

MS identity checks that the mass matches the cyclic structure (molecular weight 1024.2 g/mol in the table above), and HPLC purity shows how much of the lot is that product.

How to order

Ordering Melanotan II from Medabol

Kit and minimum
Melanotan II is sold by the kit: 10 vials of one specification (10 mg). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.

Documents
Every lot has its own COA with HPLC purity and MS identity; the order ships with the certificate of its lot, and our sales team sends it before you order if you ask.
Shipping
Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment
Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal
Listed under Skin, hair & pigment — Copper peptides, cosmetic-science peptides and melanocortin analogues.
