Kisspeptin-10 vs CJC-1295 & Ipamorelin
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 →CJC-1295 & Ipamorelin
The most popular growth hormone secretagogue combination. CJC-1295 (a GHRH analog) and Ipamorelin (a ghrelin mimetic) work synergistically to stimulate natural growth hormone release with potentially greater effects than either peptide alone.

| Aspect | Kisspeptin-10 | CJC-1295 & Ipamorelin |
|---|---|---|
| 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. | CJC-1295 binds to GHRH receptors to sustain GH signaling and extend the half-life of growth hormone release. Ipamorelin triggers strong GH pulses by binding to ghrelin receptors. Together, they create both sustained and pulsatile GH release patterns that more closely mimic natural physiology. |
| Typical Dosage | Research protocols vary widely. Studies have used IV boluses of 1-10mcg/kg or subcutaneous administration. Clinical applications still being developed. | CJC-1295 (no DAC/Mod GRF 1-29): 100-300mcg combined with Ipamorelin 200-300mcg, administered 1-3 times daily. Best results when administered fasted or before sleep. |
| Administration | IV or subcutaneous injection. Has very short half-life requiring frequent administration or continuous infusion for sustained effects. | Subcutaneous injection. Often administered before bedtime to enhance natural nighttime GH release, or in the morning fasted. The combination is typically pre-mixed or injected simultaneously. |
| Side Effects | Limited data. May cause flushing, increased heart rate, and changes in libido. Generally well-tolerated in studies. | Water retention, tingling in extremities, mild headaches, lightheadedness, or increased hunger. Generally well-tolerated with minimal effect on cortisol or prolactin. |
