Melanotan & Pigmentation

Melanotan & Pigmentation Research Peptides

The melanotan and pigmentation category contains research peptides studied in melanocortin receptor research, melanin synthesis research models, and central nervous system pathway research. These compounds are characterized as synthetic α-MSH analogs with modified pharmacokinetic profiles compared to native α-MSH.

Compounds in this category

• Melanotan II (MT-2) — Synthetic cyclic heptapeptide. Analog of α-melanocyte-stimulating hormone (α-MSH) with binding affinity at melanocortin receptors MC1R, MC3R, MC4R, and MC5R.
• PT-141 (Bremelanotide) — Synthetic seven-amino-acid melanocortin agonist derived from Melanotan II. Selective for MC3R and MC4R receptors. Most-characterized of the melanocortin research peptides in clinical literature.

Research applications

The compounds in this category are studied in: melanocortin receptor binding research, melanin synthesis research in dermal models, central nervous system receptor activity research, and appetite-modulation research models. Research on this peptide class spans both academic research and pharmaceutical research-and-development contexts.

Quality standards at VialPepLab

Every batch is HPLC-verified to ≥99% purity with LC-MS identity confirmation. The cyclic structure of Melanotan II requires specific analytical methods to verify correct disulfide bridge formation; this is documented on the COA. PT-141 follows standard linear peptide analytical protocols.

All compounds in this category are sold strictly for in-vitro laboratory research. Not for human or veterinary use.
