PT-141
Also known as: Bremelanotide · PT141
Bremelanotide — a melanocortin-receptor agonist studied for sexual arousal and libido via central nervous-system pathways.
PT-141 (bremelanotide) is a synthetic cyclic heptapeptide derived from the melanocortin peptide alpha-MSH. Rather than acting on blood flow, it is studied for acting centrally on melanocortin receptors in the nervous system.
Its research literature centres on sexual arousal and libido in both sexes, mediated through melanocortin signalling. It is chemically related to the melanocortin / alpha-MSH family that also includes the anti-inflammatory fragment KPV.

Alpha-MSH
A melanocortin hormone controlling pigmentation and inflammation; the parent of peptides such as KPV and PT-141.
Receptor / Agonist
A receptor is a cell’s signal-receiving protein; an agonist binds it and activates it, an antagonist blocks it.
Cyclic Peptide
A peptide whose chain is joined into a ring, giving greater stability and often better receptor selectivity.
KPV
A tripeptide (lysine-proline-valine) from the C-terminus of alpha-MSH, studied for anti-inflammatory and gut-calming effects.
