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.
Efinopegdutide
Human trials have shown meaningful weight loss and improvements in hepatic steatosis biomarkers. It remains a research compound with ongoing development in metabolic disease.
