Synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH). Originally developed at University of Arizona as a sunless tanning agent. Found to cause spontaneous erections in male trial subjects, leading to development for erectile dysfunction. Also promotes skin pigmentation via melanocortin-1 receptor activation.
Activates melanocortin receptors (MC1R for pigmentation, MC4R for sexual function). Stimulates melanin production and modulates sexual arousal pathways.
0.5-1mg subQ daily for tanning; 0.25-0.5mg as needed for sexual effects. Do not exceed 2mg/day.
Refrigerate 2-8°C. Protect from light. Reconstitute with bacteriostatic water.
