Melanotan-2 Research Overview
Melanotan-2 is a cyclic 7-amino-acid synthetic analog of α-MSH developed at the University of Arizona. Unlike Melanotan-1 it binds all four melanocortin receptors (MC1R, MC3R, MC4R, MC5R), producing pigmentation plus libido and appetite effects.

Molecular formula C₅₀H₆₉N₁₅O₉, molecular weight 1024.18 g/mol, sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂. MT-2's pan-melanocortin activity drives melanogenesis via MC1R, sexual arousal via MC4R (the same pathway later isolated as PT-141), and adipocyte modulation via MC5R. Its non-selectivity is why PT-141 was later developed as a libido-specific spinoff. Melanotan-2 is supplied as lyophilized powder and is classified in our catalog under α-msh cyclic analog for α-msh cyclic analog work. Recorded research categories for this compound include melanocortin pharmacology research, pigmentation and tanning research, mc4r-mediated sexual response studies, appetite and body composition research. Handling notes: store at -20°c (freezer), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for Melanotan-2: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions
How is Melanotan-2 different from PT-141?
PT-141 (Bremelanotide) is a derivative of Melanotan-2 modified to act primarily on MC4R for sexual arousal research, with much weaker MC1R/pigmentation activity. MT-2 hits all four melanocortin receptors.
What are common research dosing protocols?
Published protocols vary widely. Refer to original melanocortin literature for full dose-response data — this product is sold strictly for in-vitro research, not human use.
Do you provide a Certificate of Analysis?
Yes. ≥99.4% HPLC purity, mass-spec confirmation, endotoxin testing on every batch.
What is Melanotan-2 studied for?
Melanotan-2 appears in laboratory research covering skin pigmentation, appetite research, sexual function studies. All references describe in-vitro and preclinical study models only.
Does Melanotan-2 include a Certificate of Analysis?
Yes. Each Melanotan-2 lot ships with a batch-specific third-party Certificate of Analysis reporting 99.4% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.
What form does Melanotan-2 arrive in?
Melanotan-2 is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
