Bremelanotide

Stronger clinical signal

A melanocortin-receptor agonist derived from Melanotan II research, FDA-approved as Vyleesi for hypoactive sexual desire disorder (HSDD) in premenopausal women. Notable as one of the only peptides in this category with a formal drug approval.

Sexual health

Melanotan II

Limited human data

A non-selective melanocortin-receptor agonist originally studied for skin tanning and erectile dysfunction, whose sexual-desire side effects led directly to the development of the FDA-approved drug bremelanotide (PT-141). Widely sold gray-market for tanning despite no approval for that use.

Sexual health

Gonadorelin

Limited human data

The synthetic form of the body's own gonadotropin-releasing hormone, historically FDA-approved for pituitary function testing and pulsatile ovulation induction. Now widely discussed off-label alongside testosterone replacement therapy to help preserve natural testicular function and fertility.

Sexual health

Kisspeptin-54

Limited human data

A naturally occurring neuropeptide that is the master regulator of the reproductive hormone axis, now in early clinical development as a fertility and psychosexual therapeutic. Distinct from the melanocortin-based sexual-health peptides: it works directly on the reproductive hormone cascade.

Evidence labels

  • EmergingMostly preclinical or early signals; human athletic data is thin.
  • Limited human dataSome human pharmacology or small studies; outcomes for fitness use remain limited.
  • Stronger clinical signalSupported by larger clinical trials in defined medical populations.
