CJC-1295 vs GHRP-2: Head-to-Head Comparison
CJC-1295 and GHRP-2 represent the two main arms of GH secretion: GHRH and ghrelin pathways. CJC-1295 is a GHRH analog that provides sustained GH elevation, while GHRP-2 is a ghrelin mimetic that triggers acute GH pulses. They are frequently stacked for synergistic effects.
Side-by-Side Comparison
| Dimension | CJC-1295 | GHRP-2 |
|---|---|---|
| Evidence Level | Phase II trials, PK data published | Extensive clinical research |
| FDA Status | Not approved | Not approved |
| Mechanism | GHRH receptor agonist (amplifies GH release) | Ghrelin receptor agonist (triggers GH pulses) |
| GH Release Pattern | Sustained elevation over hours/days | Acute, potent GH pulse |
| Side Effects | Injection site reactions, water retention | Hunger increase, cortisol/prolactin elevation |
| Dosing Frequency | 1-2x weekly (DAC) or daily (no DAC) | 2-3x daily for optimal pulsing |
| Synergy Potential | Best combined with a GHRP | Best combined with a GHRH analog |
Peptide Overviews
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.
GHRP-2
BHuman StudiesGHRP-2 is a synthetic hexapeptide growth hormone secretagogue. It is one of the most potent GHRPs and has been used in clinical research for GH deficiency diagnosis.
