Research Overview

Bremelanotide

Human studies and approval data support meaningful effects on sexual desire in women, with a central mechanism involving melanocortin signaling. It is one of the most clinically relevant peptides in this category and is commonly used as the reference compound for PT-141-type research.

Plecanatide

Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
