What It Is & How It Works
CJC-1295 DAC (Drug Affinity Complex) is a synthetic peptide analog of growth hormone-releasing hormone (GHRH). It is designed to stimulate the pituitary gland to increase endogenous growth hormone (GH) production, which may support recovery, muscle growth, fat metabolism, and overall wellness.
The DAC modification allows for a longer half-life, providing sustained GH release over approximately one week per injection, compared to standard GHRH peptides.
Dosage & Storage Information
- Typical Dosage: 1–2mg per week (subcutaneous injection), often split into 1–2 doses.
- Administration: Subcutaneous injection, following sterile technique.
- Reconstitution: Reconstitute with bacteriostatic water as per manufacturer instructions.
- Storage: Store lyophilized powder in a refrigerator (2–8°C). Once reconstituted, store in the refrigerator and use within 21–28 days.
COA / Testing Explanation
A Certificate of Analysis (COA) verifies the purity, identity, and potency of CJC-1295 DAC. Reputable suppliers test each batch using techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry. The COA ensures the product meets quality standards, free from contaminants or degradation.
Always request a COA when purchasing peptides. It confirms the product has been independently tested and matches label claims.

Comparison vs Alternatives
CJC-1295 DAC is often compared to other growth hormone-related peptides such as Sermorelin and Ipamorelin:
| Peptide |
Mechanism |
Half-Life |
Primary Use |
| CJC-1295 DAC |
Stimulates GH release via GHRH receptor |
~1 week (DAC extends half-life) |
Systemic recovery, body composition support, anti-aging |
| Sermorelin |
Stimulates GH release via GHRH receptor |
~10–20 min |
GH deficiency support, recovery |
| Ipamorelin |
Ghrelin receptor agonist → stimulates GH release |
~2 hours |
GH support, appetite regulation, recovery |
Key Takeaway: CJC-1295 DAC provides longer, sustained GH stimulation, reducing the need for daily injections compared to other GHRH or GH secretagogues.
CJC-1295 vs CJC-1295 DAC
The main difference is the half-life and dosing frequency. CJC-1295 DAC lasts much longer in the body, meaning fewer injections are needed, while regular CJC-1295 requires daily administration.

FAQ
How does CJC-1295 DAC 5mg work?
CJC-1295 DAC binds to GHRH receptors and, due to the DAC modification, remains in circulation longer — encouraging sustained growth hormone release compared to non-DAC GHRH analogues.
How long before I see results?
Many users report measurable changes (recovery, sleep, body composition) in approximately 4–6 weeks, but results vary with diet, training, and dose. Track progress and adjust under guidance.
Is it safe to combine CJC-1295 DAC with other peptides?
Combining with peptides like Ipamorelin is common and can be effective, but stacking increases overall GH stimulation — so medical supervision is recommended to tailor dosing and minimise side effects.

Peptide Storage Instructions:
CJC-1295 DAC 5mg is supplied as a sterile, lyophilized (freeze-dried) powder in sealed vials. Proper storage is critical to preserve peptide stability and integrity.
Lyophilized powder (unopened vial):
Store in a dry, desiccated environment at temperatures below −18 °C, with −20 °C or −80 °C recommended for long-term storage. Protect from light and moisture at all times. Under these conditions, the lyophilized material remains stable for several years. Short-term storage at room temperature (up to three weeks) is acceptable, provided the vial remains sealed and shielded from humidity and light.
After reconstitution:
Reconstitute the powder using sterile, bacteriostatic water in a controlled laboratory setting, following appropriate biosafety procedures. Once CJC-1295 DAC 5mg is reconstituted, store the solution at 2–8 °C for short-term use (approximately 3–4 weeks), or freeze aliquots at −20 °C or lower for extended storage. Repeated freeze–thaw cycles should be avoided, as they accelerate degradation. For long-term storage, preparing sterile aliquots prior to initial freezing is strongly recommended.
All storage containers should be protected from direct light and kept sealed, preferably in opaque containers with desiccant when applicable. Prevent any moisture exposure to the lyophilized powder during storage.
