Introduction
CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH). It was engineered to extend plasma half-life by binding to serum albumin through a DAC (drug affinity complex) modification.
Mechanism of Action
CJC-1295 increases growth hormone release by:
- •Pituitary stimulation — mimics endogenous GHRH signalling
- •Pulsatile GH release — preserves natural secretory patterns
- •Albumin binding — DAC variant extends half-life to several days
- •IGF-1 elevation — downstream mediator of anabolic effects
With DAC vs Without DAC
| Feature | CJC-1295 With DAC | CJC-1295 No DAC (Mod GRF 1-29) |
|---|---|---|
| Half-life | ~6–8 days | ~30 minutes |
| Dosing frequency | 1–2x per week | 1–3x per day |
| Albumin binding | Yes | No |
| GH pulse quality | Sustained elevation | Sharp, physiological pulses |
Research Applications
Preclinical studies have investigated CJC-1295 for:
- **Body composition research** — lean mass and fat metabolism
- **Recovery models** — tissue repair and collagen synthesis
- **Aging research** — GH axis restoration in somatopause models
- **Sleep and cognition** — potential effects on REM sleep architecture
Research Considerations
The with-DAC variant produces a more sustained GH/IGF-1 elevation, which may be advantageous for some research models but can also increase water retention and insulin sensitivity considerations. Researchers should select the variant based on study design.
Conclusion
CJC-1295 remains a cornerstone GHRH analogue in peptide research. Its versatility across dosing schedules and variants makes it suitable for a wide range of preclinical investigations.
