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.

Cotadutide

Phase 2 studies reported dose-dependent weight loss and favorable changes in glycemic and liver-related markers. It is one of the most cited synthetic dual-agonist peptides for obesity research.
