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.

DSIP

DSIP has moderate clinical evidence from European studies. Human trials show improved sleep quality and normalized sleep-wake cycles. Also studied for alcohol and opiate withdrawal. Unique mechanism distinct from traditional sleep aids.
