Sexual Health Peptides

Sexual-health peptides work through two distinct systems. PT-141 activates the MC4R melanocortin receptor and is FDA-approved (as Vyleesi) for women, with documented off-label use for male erectile dysfunction; Oxytocin acts on social bonding and attachment pathways, and is frequently studied alongside PT-141 as a combination. Kisspeptin sits further upstream among these 4 compounds, regulating the GnRH-to-LH/FSH reproductive hormone axis rather than acting directly on sexual response.
