GHRP-2 vs CJC-1295 & Ipamorelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
GHRP-2
Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.
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 | GHRP-2 | CJC-1295 & Ipamorelin |
|---|---|---|
| Mechanism | Binds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6. | 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 | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. | 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 | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. | 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 | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. | Water retention, tingling in extremities, mild headaches, lightheadedness, or increased hunger. Generally well-tolerated with minimal effect on cortisol or prolactin. |
