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.
Nafarelin
Nafarelin has a long history in reproductive medicine, especially for endometriosis and cycle suppression. Studies show it down-regulates the HPG axis after an initial stimulatory flare.
