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.

Elamipretide

Clinical and translational studies show elamipretide can improve mitochondrial function and some functional endpoints in mitochondrial disorders. Skeletal muscle research suggests benefits are driven by energy metabolism rather than direct muscle-building effects.
