Kisspeptin-10- Summary
- Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
- Kisspeptin-10 is the biologically active C-terminal decapeptide of kisspeptin, an endogenous regulator of the reproductive axis. It acts upstream of GnRH to potently stimulate LH and testosterone release, and plays a key role in sexual arousal and libido.
- Half-Life
- ~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization
- ~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
- Admin Route

- Key Benefits
- Maintains testicular size during TRT
- Preserves fertility and sperm production during testosterone use
- Stimulates endogenous LH/FSH production
- Maintains HPG axis function during exogenous hormone use
- Used for HCG-free TRT protocols
- Helps restart natural testosterone production (PCT)
- Potently stimulates LH and testosterone
- Enhances sexual arousal and libido
- Activates HPG axis — upstream of GnRH
- May improve fertility in hypogonadotropic hypogonadism
- Increases brain activation in sexual attraction circuits
- May restore LH pulsatility in suppressed HPG axis
