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.
hBD-1
hBD-1 has been studied as part of the oral mucosal defense system and is linked to host resistance against dental pathogens. Research spans periodontitis, candidiasis, and epithelial barrier biology.
