DSIP (Delta Sleep-Inducing Peptide) vs CJC-1295 & Ipamorelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
DSIP (Delta Sleep-Inducing Peptide)
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.
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 | DSIP (Delta Sleep-Inducing Peptide) | CJC-1295 & Ipamorelin |
|---|---|---|
| Mechanism | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. | 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 30 minutes before sleep. Some protocols use it cyclically. | 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 or intramuscular injection before bedtime. Some users report better results with cyclical use. | 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 | May cause grogginess upon waking, vivid dreams, or temporary headaches. | Water retention, tingling in extremities, mild headaches, lightheadedness, or increased hunger. Generally well-tolerated with minimal effect on cortisol or prolactin. |
