Melanotan II (Research-Grade Peptide)

Synthetic melanocortin receptor agonist — for laboratory research only

Product Overview

Melanotan II is a synthetic cyclic heptapeptide developed as an analogue of α-melanocyte-stimulating hormone (α-MSH).
It functions as a non-selective agonist of melanocortin receptors, including MC1R, MC3R, MC4R, and MC5R. Melanotan II
has been investigated in preclinical and clinical research for its effects on pigmentation pathways, energy balance,
and central nervous system signaling. Supplied as a high-purity lyophilized powder, this material is intended strictly
for laboratory research use and is not approved for human or veterinary administration.

Research Highlights

• Melanocortin Receptor Activity: Melanotan II activates multiple melanocortin receptors involved in
  melanin synthesis, appetite regulation, and autonomic signaling.
  Journal of Medicinal Chemistry
• Pigmentation Research: Studies have shown increased melanogenesis following melanocortin receptor
  activation, making Melanotan II a tool compound in pigmentation and dermatological research models.
  Pigment Cell Research
• Energy Balance & CNS Studies: Research has explored Melanotan II’s interaction with MC3R and MC4R,
  receptors associated with appetite, energy expenditure, and central nervous system signaling.
  Endocrinology
• Pharmacologic Stability: Compared with endogenous α-MSH, Melanotan II exhibits enhanced resistance
  to enzymatic degradation, supporting its use in extended research protocols.
