CJC-1295 vs DSIP
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
CJC-1295
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.
Full details →DSIP
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.
Full details →Side-by-Side Comparison
| Aspect | CJC-1295 | DSIP |
|---|---|---|
| Mechanism | CJC-1295 binds to GHRH receptors in the pituitary, triggering increased production and release of growth hormone. The DAC (Drug Affinity Complex) version extends half-life significantly. | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. |
| Typical Dosage | CJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily. | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. |
| Administration | Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted. | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. |
| Side Effects | Water retention, tingling in extremities, potential increase in cortisol and prolactin levels. | May cause grogginess upon waking, vivid dreams, or temporary headaches. |
