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.

Mazdutide

Clinical programs have shown substantial reductions in body weight and improvements in cardiometabolic risk markers. It is a prominent newer dual agonist in the obesity literature.
