CJC-1295 vs Ipamorelin.
Side-by-side research comparison of CJC-1295 and Ipamorelin: dosing, half-life, side effects, and mechanism of action.
Quick Verdict
CJC-1295 + Ipamorelin is the gold-standard GH peptide stack — they act on different receptors (GHRH vs GHSR) for synergistic 2-3x greater GH output than either alone. Comparing them solo misses the point: use both together.
Side-by-Side Analysis
| Dimension | CJC-1295 | Ipamorelin |
|---|---|---|
| Mechanism | Stimulates prolonged GH and IGF-1 release by mimicking the body's natural GHRH signal to the pituitary gland. | Selective GH secretagogue that mimics ghrelin at the GHS receptor. |
| Primary Benefits | Muscle growth, fat loss, recovery | GH release, muscle growth, recovery without cortisol spike |
| Typical Dose | 1000–1000mcg | 300–300mcg |
| Route | SubQ | SubQ |
| Frequency | 3x/week | 7x/wk |
| Half-Life | 168 hours | 2 hours |
| FDA Status | Approved | Approved |
| Evidence Grade | moderate | moderate |
| Key Studies | 20+ indexed | 20+ indexed |
| Lowest Price | $59.99 / 10mg via Amino Club | $50.00 / 5mg via Ascension Peptides |
Which one should you choose?
Who Should Choose CJC-1295?
Choose CJC-1295 solo if you:
- Want sustained basal GH elevation without a GHRP
- Are sensitive to the appetite-stimulating effects of GHRPs
- Are using the DAC variant and want weekly dosing convenience
- Are stacking with a different GHRP (e.g., GHRP-2 for more potency)
Who Should Choose Ipamorelin?
Choose Ipamorelin solo if you:
- Want the safest possible GH stimulation with zero cortisol/prolactin elevation
- Are new to GH peptides and want a clean, well-tolerated starting point
- Cannot or prefer not to use a GHRH analog at this time
- Are researching GH pulsatility without sustained IGF-1 elevation
Can you stack CJC-1295 + Ipamorelin?
The CJC-1295 (without DAC) + Ipamorelin stack is the most prescribed peptide combination in anti-aging and sports recovery research. CJC-1295 amplifies the GH pulse amplitude; Ipamorelin triggers the pulse via the GHSR-1a receptor. Together, they mimic and amplify the natural pituitary GH release mechanism. Inject simultaneously before bed.

Frequently Asked Questions
Yes — this is the most universally recommended GH peptide stack. They act on completely separate receptor systems (GHRH vs GHSR) producing a synergistic 2-3x amplification of GH output vs either peptide alone. Most vendors sell a premixed blend.
