What Is Kisspeptin-10?

Kisspeptin-10 is the short active fragment of kisspeptin, the master switch of the reproductive hormone axis — it sits above GnRH, which sits above LH/FSH, which drive testosterone and estrogen. Discovered in Hershey, Pennsylvania (hence the chocolate-inspired name), it initiates puberty and regulates fertility signaling.

Research use targets the top of the cascade: stimulating natural hormone production without directly suppressing it, plus intriguing human studies on sexual and emotional brain responses.

Legal & approval status

Research chemical; no approvals, though it appears in legitimate human research regularly.

Typical dosing at a glance

Commonly reported protocols use 100 mcg–200 mcg, 1–3x weekly, via subcutaneous injection. For the mixing math — how much bacteriostatic water, exact syringe units, doses per vial — see the Kisspeptin-10 reconstitution calculator →
