Overview
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that enhances the production and release of growth hormone from the pituitary gland. As a long-acting GHRH analog, it provides sustained elevation of growth hormone levels, making it highly effective for body composition improvement, anti-aging, and recovery enhancement.
Available in two forms - with and without Drug Affinity Complex (DAC) - CJC-1295 has become one of the most popular peptides for growth hormone optimization. The DAC version provides extended half-life, while the non-DAC version (often called Mod GRF 1-29) offers more natural pulsatile release patterns.
CJC-1295 is frequently combined with Ipamorelin to create a powerful complementary effect, with CJC-1295 amplifying growth hormone pulses and Ipamorelin increasing their frequency.
How It Works
- GHRH receptor activation: Binds to growth hormone-releasing hormone receptors in the pituitary
- GH pulse amplification: Increases the amplitude of natural growth hormone release
- Extended half-life: DAC version provides sustained activity for days
- IGF-1 elevation: Increases insulin-like growth factor 1 levels
- Metabolic enhancement: Improves protein synthesis and fat oxidation
Benefits
- Enhanced muscle growth: Increased lean muscle mass and strength
- Fat loss: Improved body composition and metabolic rate
- Better recovery: Faster healing from workouts and injuries
- Improved sleep: Enhanced deep sleep and recovery
- Anti-aging effects: Better skin, hair, and overall vitality
- Bone health: Increased bone density and strength
- Immune function: Enhanced immune system response
- Cognitive benefits: Improved memory and mental clarity
Potential Risks & Side Effects
Common Side Effects
- Injection site reactions
- Water retention
- Joint stiffness
- Carpal tunnel symptoms
DAC vs Non-DAC Considerations
- DAC version: Longer half-life but less natural pulsing
- Non-DAC: More natural patterns but requires more frequent dosing
Typical Protocol
CJC-1295 with DAC
- Dose: 1-2 mg twice weekly
- Timing: Morning and evening
CJC-1295 without DAC (Mod GRF 1-29)
- Dose: 100-300 mcg 2-3 times daily
- Stack: Often combined with Ipamorelin
