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.

Ipamorelin

Ipamorelin has moderate clinical evidence. Phase II trials demonstrate selective GH release. Generally regarded as one of the safest GH secretagogues with minimal side effect profile.
