A melanocortin agonist studied for sexual arousal and desire in both men and women.
In the literature, PT-141 appears most often in work focused on libido and sexual function. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.
PT-141 is catalogued here under powder peptides. Coverage of this compound varies in quality and depth, and much of it remains early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.

Melanotan II is a synthetic alpha-MSH analog that non-selectively activates melanocortin receptors, leading to increased skin pigmentation, appetite suppression, and enhanced sexual function. It is primarily known for its tanning effects.
RFRP-3 is a neuropeptide that inhibits the reproductive axis at multiple levels. Researchers study its potential role in regulating fertility and sexual function.
A reproductive-axis peptide studied for libido, testosterone signaling, and fertility.
