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.
hCG
Human studies show hCG can raise intratesticular and serum testosterone by mimicking luteinizing hormone at the testis. It is commonly studied in male hypogonadism and fertility-preservation settings.
