What is CJC-1295 DAC?
CJC-1295 DAC is a synthetic growth hormone-releasing hormone (GHRH) analog that has been modified with a Drug Affinity Complex (DAC) to extend its half-life in the bloodstream. It is designed to stimulate the pituitary gland to increase endogenous growth hormone (GH) production over extended periods. This peptide is studied for its potential to enhance muscle growth, recovery, and fat metabolism while supporting research into aging, regenerative medicine, and metabolic health. The DAC modification allows for less frequent dosing while maintaining sustained GH release.
Mechanism of Action:
CJC-1295 DAC binds to GHRH receptors in the anterior pituitary gland, stimulating the release of growth hormone (GH) into the bloodstream. The DAC component prolongs its half-life, allowing sustained GH secretion over 1–2 weeks per injection. Increased GH triggers elevated IGF-1 levels, promoting muscle protein synthesis, tissue repair, and lipolysis. Its mechanism also indirectly supports cellular regeneration, collagen production, and overall anabolic processes, making it a key peptide in research focusing on musculoskeletal enhancement and age-related decline.
Benefits:
- Enhances muscle mass, strength, and recovery in research studies.
- Promotes fat metabolism and improved body composition.
- Supports tissue repair and regenerative processes, including connective tissue.
- Increases IGF-1 levels, contributing to systemic anabolic and anti-aging effects.
Research Applications:
- Studying muscle wasting prevention in sarcopenia models.
- Evaluating metabolic improvements, including fat loss and energy regulation.
- Investigating collagen synthesis and tissue regeneration.
- Exploring age-related hormone deficiency treatments and longevity research.
Dosing Instructions:
- Dosing: Varies by study protocol (commonly 1–2 mg per injection for research purposes)
- Daily Dose: Typically administered 2–3 times per week due to DAC half-life
- Route: Subcutaneous (SC) injection
- Duration: Research studies often run 4–12 weeks depending on objectives
- Frequency: Every 4–7 days is common for DAC formulations
- Recommended Cycles: Determined by study design, generally 4–12 weeks
- PCT: Not applicable for research peptides; follow lab-specific protocols
Stacking With Other Products:
- Ipamorelin to synergistically enhance GH pulsatility.
- BPC 157 for improved tissue healing alongside GH effects.
- TB 500 to accelerate connective tissue recovery.
- AOD 9604 for fat metabolism support and body composition research.
Side Effects:
- Mild injection-site irritation such as redness or tenderness.
- Temporary water retention during initial use.
- Headaches or mild fatigue in early administration.
- Minimal systemic side effects; generally well-tolerated in clinical research.
Contraindications:
- Hypersensitivity to CJC-1295 DAC or any excipients.
- Active cancer or tumors due to GH stimulation risk.
- Severe cardiovascular or kidney conditions without physician oversight.
- Pregnant or breastfeeding individuals, due to lack of human safety data.
Conclusion
CJC-1295 DAC is a potent and long-acting GHRH analog designed to safely enhance endogenous growth hormone release over extended periods. It is widely used in research focused on muscle growth, fat metabolism, tissue repair, and anti-aging studies. Its prolonged half-life and synergy with peptides such as Ipamorelin and BPC 157 make it a valuable tool in experimental medicine and musculoskeletal recovery research. Proper handling, storage, and adherence to research dosing protocols are essential to maximize efficacy and study accuracy.

CJC-1295 DAC FAQ
✔️ What is CJC-1295 DAC and how does it work?
CJC-1295 DAC is a growth hormone–releasing peptide (GHRH analogue) designed to stimulate the body’s natural growth hormone production. The DAC (Drug Affinity Complex) extends the peptide’s half-life, allowing for longer and more stable hormone stimulation.
✔️ What benefits are commonly associated with CJC-1295 DAC?
Many users report improvements in muscle recovery, lean muscle development, fat metabolism, sleep quality, and overall physical performance due to increased growth hormone and IGF-1 levels.
✔️ How is CJC-1295 DAC typically administered?
CJC-1295 DAC is usually administered via subcutaneous injection. Because of its extended half-life, it is often used less frequently compared to other growth hormone peptides.
✔️ What makes CJC-1295 DAC different from regular CJC-1295?
The main difference is the DAC modification, which significantly extends the peptide’s half-life. This allows CJC-1295 DAC to remain active in the body for several days, providing sustained growth hormone release.
✔️ How should CJC-1295 DAC be stored?
Before mixing, store the vial in a cool, dry place away from light. After reconstitution, keep CJC-1295 DAC refrigerated at 2–8°C (36–46°F) to maintain peptide stability and potency.
✔️ Can CJC-1295 DAC be stacked with other peptides?
Yes, CJC-1295 DAC is often combined with peptides such as Ipamorelin or GHRP peptides to create a synergistic growth hormone release protocol.
✔️ How long does CJC-1295 DAC stay active in the body?
Due to the DAC modification, CJC-1295 DAC can remain active for several days, supporting a prolonged release of growth hormone compared to shorter-acting peptides.
✔️ Who typically uses CJC-1295 DAC?
Athletes, bodybuilders, and performance-focused individuals commonly explore CJC-1295 DAC for its potential role in recovery support, muscle development, and overall performance optimization.
