Research Overview
Buserelin
Buserelin has been studied extensively as a GnRH agonist in IVF down-regulation and other reproductive-endocrine protocols. Its use helped establish modern cycle-control approaches in assisted reproduction.
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.
