Kisspeptin-10 vs Hexarelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Kisspeptin-10
Kisspeptin-10 is the active fragment of kisspeptin, a hormone that plays a crucial role in initiating puberty and regulating reproductive function. It acts upstream of GnRH in the hypothalamic-pituitary-gonadal axis.
Full details →Hexarelin
Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.
Full details →Side-by-Side Comparison
| Aspect | Kisspeptin-10 | Hexarelin |
|---|---|---|
| Mechanism | Binds to KISS1R receptors in the hypothalamus, stimulating GnRH neurons to release GnRH. This triggers the downstream cascade of LH, FSH, and sex hormone production. | Acts as a ghrelin mimetic with high potency at the GHS receptor. Provides powerful GH release but receptor desensitization occurs faster than with other GHRPs, requiring cycling. |
| Typical Dosage | Research protocols vary widely. Studies have used IV boluses of 1-10mcg/kg or subcutaneous administration. Clinical applications still being developed. | Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization. |
| Administration | IV or subcutaneous injection. Has very short half-life requiring frequent administration or continuous infusion for sustained effects. | Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols. |
| Side Effects | Limited data. May cause flushing, increased heart rate, and changes in libido. Generally well-tolerated in studies. | Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects. |
