Sexual & Hormonal Peptides

Sexual and hormonal compounds include melanocortin receptor agonists and peptides that act on the hypothalamic-pituitary-gonadal axis, studied in reproductive and sexual-health research. The group spans FDA-approved products and research-only materials, so handling and regulatory status vary widely from entry to entry.

PT-141

Bremelanotide · Vyleesi

A synthetic melanocortin receptor agonist that acts on central pathways involved in sexual arousal. FDA-approved as Vyleesi and studied for hypoactive sexual desire disorder in premenopausal women.

Half-life · ~2.7 h terminal (range 1.9-4.0 h)FDA approved
Melanotan II
Sexual / HormonalVerified

Melanotan II

MT-2 · MT2

A synthetic cyclic analog of alpha-melanocyte-stimulating hormone acting as a non-selective melanocortin receptor agonist. Studied in relation to skin pigmentation and, via MC4R activation, sexual arousal. Not FDA-approved.

Half-life · ~1 hNot FDA approved
Kisspeptin
Sexual / HormonalVerified

Kisspeptin

Kisspeptin-10 · Kisspeptin-54

Endogenous neuropeptides (KISS1 products) that agonize the KISS1R/GPR54 receptor on hypothalamic GnRH neurons, stimulating pulsatile GnRH release and downstream LH and FSH secretion. Studied in reproductive neuroendocrinology and fertility research.

Half-life · Kisspeptin-10 ~4 min; kisspeptin-54 ~27.6 minResearch only
Gonadorelin
Sexual / HormonalVerified

Gonadorelin

GnRH · Factrel

A synthetic decapeptide identical to endogenous gonadotropin-releasing hormone (GnRH) that binds pituitary GnRH receptors to stimulate release of LH and FSH. Pulsatile use stimulates them; continuous use suppresses them.

Half-life · ~2-10 min (IV distribution); terminal ~10-40 minFDA approved
HCG
Sexual / HormonalVerified

HCG

Human Chorionic Gonadotropin · Novarel

A glycoprotein hormone that acts as a functional analog of luteinizing hormone, binding LH/CG receptors to stimulate gonadal steroidogenesis. FDA-approved for uses including ovulation induction and certain hypogonadotropic conditions. Dosed in international units.

Half-life · Biphasic; terminal ~24-36 hFDA approved
Oxytocin
Sexual / HormonalVerified

Oxytocin

Pitocin

An endogenous nonapeptide hormone. Its approved label covers obstetric use rather than the social or behavioural effects it is often discussed for, and it is cleared from plasma within minutes.

Half-life · ~1 to 6 min in plasmaFDA approved
Afamelanotide
Sexual / HormonalVerified

Afamelanotide

Scenesse · Melanotan-1 · Melanotan I

A melanocortin-1 receptor agonist approved to increase pain-free light exposure in adults with erythropoietic protoporphyria, a rare photosensitivity disorder. It is delivered as a controlled-release implant. Its approved use is photoprotection, not weight, performance or sexual function.

Half-life · ~15 hFDA approved
