Product Overview of Melanotan II (Acetate)
Melanotan II (Acetate) Powder is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH), designed to activate multiple melanocortin receptors (MC1R, MC3R, MC4R, MC5R) with high affinity.
Primary applications of Melanotan II (Acetate) Powder span dermatological research (e.g., skin pigmentation modulation), neuroendocrine studies (e.g., appetite regulation), and sexual health research (e.g., erectile dysfunction mechanisms).
As a research-grade peptide, it is strictly intended for laboratory use and not for human consumption.

Key Applications of Melanotan II (Acetate)
Dermatological Research of Melanotan II (Acetate)
- Skin Pigmentation: Induces melanogenesis by binding to MC1R, increasing eumelanin production for darker skin tones.
- Photoprotection: Reduces UV-induced DNA damage in preclinical models, offering potential as a sunless tanning agent.
Neuroendocrine & Metabolic Studies of Melanotan II (Acetate)
- Appetite Suppression: Acts on MC3R/MC4R to reduce food intake in rodent models, with implications for obesity research.
- Energy Expenditure: Enhances oxygen consumption and thermogenesis, influencing metabolic rate studies.
Sexual Health Research of Melanotan II (Acetate)
- Erectile Dysfunction (ED): Demonstrates rapid onset of libido enhancement and spontaneous erections in preclinical trials, attributed to central nervous system activation.
Neurological & Nerve Repair of Melanotan II (Acetate)
- Peripheral Nerve Injury: Improves sciatic nerve function recovery in rats post-mechanical trauma.
- Neuroprotection: Modulates sensory nerve conduction velocity in cisplatin-induced neuropathy models.
