UK supplier comparison
Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

For in-vitro laboratory research only
Melanotan II is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.
Research profile
About Melanotan II in the lab
A synthetic cyclic analogue historically used to study melanocortin-receptor structure–activity relationships.
Proposed mechanism
Cyclic lactam analogue of alpha-MSH that activates several melanocortin receptors (MC1R, MC3R, MC4R and others), affecting pigmentation via MC1R and central pathways via MC3R/MC4R in models.
Structure note
Cyclic lactam analogue of α-melanocyte-stimulating hormone (Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2).
Typical research themes
- MC1R–MC5R binding
- SAR studies
- Cyclic-peptide stability
Regulatory note
Unlicensed as a medicine in the UK; medicines regulators have issued public warnings about products sold for human use. Research material is for in-vitro use only.
This profile is a short, general summary of publicly discussed science. It is not exhaustive, not peer-reviewed by PeptideCompare, and is not medical advice. PeptideCompare provides no dosing, protocol or usage guidance — nothing here is for human or veterinary use.
