What is Melanotan II (MT-2) 10MG?
Melanotan II is a synthetic cyclic peptide analogue of the natural hormone Alpha‑melanocyte stimulating hormone (α-MSH). It was developed in the 1980s and acts as a non-selective agonist of multiple melanocortin receptors (including MC₁R, MC₃R, MC₄R and MC₅R) in order to explore pathways involving pigmentation, energy homeostasis, neuroendocrine signalling and sexual physiology.
Chemical Structure of Melanotan II (MT-2) 10MG
-
Sequence (simplified): Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂ (a cyclic heptapeptide)
-
Molecular formula: C₅₀H₆₉N₁₅O₉
-
Approximate molecular weight: ~1,024.2 g/mol
-
Mechanistic note: The cyclic structure and non-natural amino acid residues enhance receptor affinity and metabolic stability compared to the native hormone.
What Are the Effects of Melanotan II (MT-2) 10MG?
-
Pigmentation / Melanogenesis: Through activation of MC₁R on melanocytes, Melanotan II stimulates eumelanin production, leading to increased skin tanning and darker pigmentation even with minimal UV exposure.
-
Appetite & Energy Regulation: Activation of MC₃R/MC₄R pathways has been linked to reduced food intake, increased satiety, and effects on energy balance.
-
Sexual & Reproductive Effects: In early human research, MT-2 has shown to induce spontaneous penile erections and increased sexual desire via central melanocortin receptor activation (MC₄R) in the brain.
-
Research & Safety Considerations: While studied in multiple models, Melanotan II is not approved for human therapeutic use. Use has been linked with serious safety concerns such as increased mole/nevus pigmentation, potential melanoma risk, kidney and systemic toxicity (e.g., rhabdomyolysis) in unregulated use scenarios.
