Sexual health is one of the most underserved areas in peptide research — and one of the most impactful. These peptides work through the brain's melanocortin system and hormonal pathways to address desire, arousal, and performance at the root level. PT-141 (Bremelanotide) is the only FDA-approved option for women with HSDD, and it works for men too.
PT-141 is the only peptide that works directly through the brain's melanocortin system to increase sexual desire — not blood flow. That means it works for both men and women, and it addresses the psychological and physiological roots of low libido simultaneously. FDA-approved as Vyleesi for women with HSDD.
