MELANOTAN 2 10MG | Tanning & Libido Support

Melanotan 2 10mg is a research-grade cyclic melanocortin agonist studied for pigmentation, appetite and sexual-arousal pathways. This 3 ml vial containing 10 mg presentation is intended for laboratory investigation of combined MC1R, MC3R and MC4R activation. Melanotan 2 is a cyclic alpha-MSH analog that activates MC1R, MC3R and MC4R. MC1R activation drives melanogenesis and skin darkening, while MC4R activation influences appetite and energy balance, and MC3R/MC4R signalling is linked to sexual arousal and erectile function.

This broader receptor profile distinguishes it from the MC1R-selective Melanotan 1. Dorr and colleagues (Archives of Dermatology, 2004) reported that a superpotent melanotropic peptide combined with solar UV radiation increased tanning in human volunteers. Other work has examined MC4R-mediated effects on appetite and sexual behaviour, although the clinical evidence base remains limited. Researchers use Melanotan 2 to study melanocortin receptor pleiotropy, pigmentary responses, appetite suppression and sexual-arousal circuitry.

It is also a tool for comparing MC1R-selective and non-selective melanocortin agonists. The 10 mg vial is intended for laboratory studies that require sustained receptor activation. Because MC4R engagement can reduce food intake and affect blood pressure, metabolic and cardiovascular endpoints should be monitored alongside pigmentation. For long-term storage, keep the lyophilised vial desiccated at -20C and allow it to equilibrate to room temperature before opening to prevent condensation. Reconstitute with bacteriostatic water, mix gently, and avoid vortexing or repeated freeze-thaw cycles.

Key questions concern the balance between pigmentary and central effects, the potential for receptor desensitisation, and whether the cyclic structure improves stability enough to change dosing requirements.
