About this compound
Synthetic α-MSH analogue
First disclosed
1987
Melanotan II is a cyclic lactam analogue of α-melanocyte-stimulating hormone, first prepared at the University of Arizona in the late 1980s. Because it activates several melanocortin receptors at once, it has become a standard reference ligand for melanocortin-pathway research.
Non-selective agonism across MC1R, MC3R and MC4R is studied in vitro for receptor binding and downstream cAMP signalling.

Melanotan II is a cyclic α-MSH analogue known as Melanotan II, supplied by MyPeptides for laboratory research use only.
Melanotan II is a cyclic α-MSH analogue known as Melanotan II. MyPeptides supplies it as a lyophilised 10 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Melanotan II in pigmentation and MC receptor-family research. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Melanotan II order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. Cyclic backbone gives broader MC receptor activity than Melanotan I.
Straight answers on purity, handling, dispatch and research use.
Melanotan II is a cyclic α-MSH analogue known as Melanotan II, supplied by MyPeptides as a lyophilised research vial for laboratory research use only.
In cited literature, Melanotan II is studied in pigmentation and MC receptor-family research. It is not a medicine and is not intended for human or veterinary use.
Every batch is third-party HPLC assayed at ≥99% purity. A signed certificate of analysis is available on request after checkout.
Ships lyophilised in a sealed borosilicate vial. Store at −20 °C; reconstitute with bacteriostatic or sterile water immediately before in vitro use.

Documentation is what sold me. Independent CoA per batch, clean HPLC traces. Reconstitution behaved exactly as expected. Solid supplier for research use.
Support answered a batch question within a few hours over email. Rare to get that level of response from a research supplier. Product itself is exactly to spec.
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
Really impressed with the packaging quality. Everything double-boxed, insulated and clearly labelled. Same day dispatch worked as promised.
Ordered a bundle to save on shipping - all vials arrived in one insulated pack, labels identical batch, CoA covers the lot. Great value.
Clean product, no discoloration, correct fill. Certificate of analysis was in the box AND emailed. Very straightforward experience.
