Melanocortin Research Peptides

The melanocortin research category includes synthetic analogs of alpha-melanocyte-stimulating hormone (alpha-MSH) and related compounds that interact with the melanocortin receptor family (MC1R through MC5R). Research in this area has examined pigmentation pathways, neuroendocrine signaling, and inflammation markers across cell culture and animal model systems. Melanotan II (MT-2) is among the most commonly studied compounds in this category, valued for its receptor binding profile and stability in research conditions.

What to look for in this category

Melanocortin peptides are often supplied with TFA counter-ions, and the actual peptide content (versus net peptide weight) should be specified on the COA. This affects accurate dose calculations in receptor binding studies. Look for vendors who report peptide content alongside purity percentage, not just total weight.
