Ipamorelin vs CJC-1295: Head-to-Head Comparison
Ipamorelin is a selective ghrelin mimetic (GHRP) that triggers GH pulses, while CJC-1295 is a GHRH analog that amplifies GH release duration. They are commonly combined because their mechanisms are synergistic — CJC-1295 raises the baseline and Ipamorelin sharpens the pulse.
Side-by-Side Comparison
| Dimension | Ipamorelin | CJC-1295 |
|---|---|---|
| Evidence Level | Phase II clinical trials completed | Phase II clinical trials, published pharmacokinetics |
| FDA Status | Not approved | Not approved |
| Mechanism | Ghrelin receptor agonist (GHS-R1a) | GHRH receptor agonist with DAC for extended half-life |
| Primary Use | Pulsatile GH release, body composition | Sustained GH elevation, IGF-1 increase |
| Side Effects | Very clean; minimal cortisol/prolactin impact | Injection site reactions, water retention, flushing |
| Ease of Use | Subcutaneous injection 1-3x daily | Subcutaneous injection 1-2x weekly (DAC) or daily (no DAC) |
| GH Pulse Profile | Sharp, physiological pulses | Sustained elevation over hours/days |
Peptide Overviews
Ipamorelin
BHuman StudiesIpamorelin is a selective growth hormone secretagogue that stimulates growth hormone release from the pituitary gland without significantly affecting cortisol or prolactin levels.
CJC-1295
BHuman StudiesCJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH). Available in two forms: with and without Drug Affinity Complex (DAC), which extends its half-life.
