Other Research Peptides
Melanocortin and neuropeptide-hormone research compounds outside the main research groups. Most are melanocortin-receptor agonists that differ mainly in which MC receptors they bind; the category also lists an endogenous nonapeptide hormone salt used as a receptor reference ligand. Laboratory research use only, not for human or veterinary use.

Melanotan II
★★★★★ ★★★★★ 4.7 7 reviews
(Synthetic Alpha-Melanocyte Stimulating Hormone)
Cyclic α-MSH analogue studied for non-selective melanocortin-receptor agonism, including pigmentation and other melanocortin pathways, in laboratory research.
PT-141
(Bremelanotide)
Melanocortin MC3R/MC4R agonist (bremelanotide) studied for central melanocortin signalling in receptor-pharmacology research.
Melanotan-1
(Afamelanotide)
Linear α-MSH analogue (afamelanotide) studied for MC1R binding, melanogenesis and UV photoprotection pathways in laboratory research.
Oxytocin Acetate
(OXT, nonapeptide hormone)
The canonical oxytocin-receptor agonist - the first peptide hormone ever sequenced and synthesised, used across social-cognition research.
What you will find here
Melanotan I (afamelanotide) is a linear 13-amino-acid alpha-MSH analogue that acts preferentially at the MC1 receptor. Melanotan II is a cyclic heptapeptide that binds MC1, MC3, MC4 and MC5 receptors. PT-141 (bremelanotide) is an MC3/MC4 receptor agonist used in central melanocortin research. Receptor selectivity is the practical difference between the melanocortin compounds, and each product page sets it out alongside the available strengths. Oxytocin acetate is the acetate salt of the endogenous nonapeptide hormone oxytocin, used as a reference ligand for the oxytocin receptor.
