PT-141 vs Melanotan 2
Two melanocortin-receptor research peptides with shared origins but different focus.
PT-141 (bremelanotide) and Melanotan 2 both act on melanocortin receptors in research models. Melanotan 2 is broader; PT-141 is a downstream metabolite studied more narrowly.
Side-by-side
| Attribute | PT-141 | Melanotan 2 |
|---|---|---|
| Peptide class | Melanocortin agonist (MT-II metabolite) | Melanocortin-receptor agonist |
| Receptor focus | Studied primarily at MC4R | Broad MC1R–MC5R activity |
| Common research context | Central melanocortin-signaling models | Pigmentation and appetite-signaling models |
| Relationship | A research metabolite of Melanotan 2 | Parent compound to PT-141 |
| Physical form | Lyophilized powder | Lyophilized powder |
Which does the research favor?
Melanotan 2 is the broader melanocortin tool; PT-141 narrows the focus to central MC4R signaling. The choice follows the receptor pathway of interest.
