Compounds studied for reproductive, ranked by the strength of the evidence — strongest at the top, research-grade and disappointing below. Grades reflect the evidence, not marketing. This is a neutral reference; nothing here is a recommendation to use, and no compound is offered for sale.
Afamelanotide is a synthetic α-MSH analog and selective MC1R agonist — and a genuinely approved, first-in-class drug (Scenesse, EMA 2015 / FDA 2019) for the rare disease…
Kisspeptin-10 is the minimal active fragment of kisspeptin — the hypothalamic peptide that sits at the top of the reproductive hormone axis and acts as its master switch.
PT-141 (bremelanotide) is a central-acting melanocortin MC4R agonist and the active derivative of the tanning peptide Melanotan II.
