CJC-1295 No DAC & Ipamorelin vs Ipamorelin: Comparison
Mechanism GHRH receptor agonist. Amplifies endogenous GH pulse amplitude Ghrelin receptor (GHS-R1a) agonist. Initiates discrete GH pulses Dual-pathway activation: GHRH amplification + ghrelin-triggered pulse Stacking leverages two independent receptor pathways
This comparison does not assign a generated winner or score.
- Mechanism
- GHRH receptor agonist. Amplifies endogenous GH pulse amplitude
- Ghrelin receptor (GHS-R1a) agonist. Initiates discrete GH pulses
- Dual-pathway activation: GHRH amplification + ghrelin-triggered pulse
- Stacking leverages two independent receptor pathways for synergistic GH elevation
- Half-Life
- ~30 minutes (subcutaneous)
- ~2 hours (plasma)
- Both peptides administered simultaneously
- CJC's short half-life requires timing around natural pulses; Ipamorelin's longer window allows flexibility
- GH Elevation Pattern
- Increases amplitude of existing pulses without creating new events
- Creates new pulse events independent of endogenous rhythm
- Combines pulse amplification with discrete pulse initiation
- Stack produces both higher peak GH and extended duration compared to either alone
- Cortisol/Prolactin Impact
- Minimal to none (GHRH pathway doesn't stimulate ACTH or prolactin)
- None (selective GHS-R1a agonism without cortisol or prolactin cross-reactivity)
- Neither compound elevates cortisol or prolactin at standard doses
- This selectivity is why Ipamorelin replaced earlier GHRPs in most protocols
- Optimal Timing
- 30–60 min before anticipated endogenous pulse (sleep, post-workout)
- Flexible. Creates pulse on-demand regardless of natural rhythm
- Pre-sleep administration captures nocturnal GH peak while adding discrete pulse
- Stacking before sleep maximizes synergy during period of highest natural secretion
- Reconstitution Stability
- 28 days refrigerated (2–8°C) after mixing with bacteriostatic water
- Pre-mixed formulations simplify storage and reduce contamination risk
- Single-vial stacks like CJC1295 Ipamorelin 5MG 5MG eliminate multi-vial management
