CJC-1295 Products for Research
What is CJC-1295?
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH). Unlike natural GHRH which has a short half-life, CJC-1295 has been modified to extend its duration of action, making it valuable for sustained growth hormone research applications.
The compound exists in two primary forms: CJC-1295 with DAC (Drug Affinity Complex) and CJC-1295 without DAC (also known as modified GRF 1-29). The no-DAC version is more commonly used in research due to its more natural pulsatile stimulation pattern.
Mechanism of Action
GHRH Receptor Activation
CJC-1295 binds to growth hormone-releasing hormone receptors in the pituitary gland, stimulating the release of growth hormone. This mechanism mimics the natural pulsatile release pattern of growth hormone in the body.
Extended Half-Life
The structural modifications in CJC-1295 (without DAC) provide a half-life of approximately 30 minutes, allowing for sustained growth hormone release compared to natural GHRH’s 7-minute half-life.
IGF-1 Stimulation
Through growth hormone release, CJC-1295 indirectly stimulates insulin-like growth factor 1 (IGF-1) production in the liver. This IGF-1 pathway is crucial for cellular growth and repair mechanisms studied in laboratory settings.
Research Applications
Growth Hormone Secretion Studies
The primary research focus for CJC-1295 involves studying growth hormone secretion patterns and mechanisms. Research areas include:
- Pulsatile growth hormone release patterns
- Pituitary gland function and response

Metabolic Research
CJC-1295 has been studied for its potential effects on metabolic processes, including glucose metabolism, lipid profiles, and cellular energy utilization.
Body Composition Studies
Research has investigated CJC-1295’s potential role in studying lean body mass, adipose tissue metabolism, and overall body composition changes in research models.
Laboratory Protocol for Beginners
Reconstitution
CJC-1295 requires proper reconstitution before laboratory use:
- Use sterile bacteriostatic water for reconstitution
- Typical concentrations: 0.1-2 mg/mL for research
- Gently swirl vial—avoid shaking or vigorous agitation
- Allow complete dissolution before use
Storage Guidelines
Proper storage maintains peptide integrity:
- Lyophilized powder: Store at -20°C (stable 2+ years)
- Reconstituted solution: 4°C, use within 14-30 days
- Protect from light exposure
- Avoid freeze-thaw cycles
Key Research Findings
Laboratory studies have demonstrated several significant findings regarding CJC-1295:
- Sustained growth hormone elevation in animal models (Teichman et al., 2006)
- Increased IGF-1 levels following administration (Ionescu & Frohman, 2006)
- Improved protein synthesis markers in research subjects
- Enhanced cellular repair mechanisms in tissue studies
Research Considerations for Beginners
Purity Verification
Always verify CJC-1295 purity through third-party HPLC analysis. Research-grade peptides should be ≥98% pure with Certificates of Analysis available.
Dosage Considerations
Research models have used various concentrations. Typical research doses range from 0.5-2 mg per administration in animal studies. Always consult current literature for specific protocols.
Regulatory Status
CJC-1295 is not approved for human use by the FDA or any international regulatory body. It is strictly for laboratory research and analytical study by qualified professionals.
Frequently Asked Questions
What is the difference between CJC-1295 with DAC and without DAC?
CJC-1295 with DAC has a longer half-life (days) due to albumin binding, while CJC-1295 without DAC (modified GRF 1-29) has a shorter half-life (30 minutes) that more closely mimics natural GHRH pulsatile release patterns.
How does CJC-1295 compare to other GHRH analogs?
CJC-1295 (no DAC) provides more natural growth hormone pulsatility compared to longer-acting analogs. This makes it valuable for studying natural growth hormone secretion patterns.
What is the shelf life of CJC-1295?
When stored properly as lyophilized powder at -20°C, CJC-1295 maintains stability for 2+ years. Reconstituted solutions should be used within 14-30 days when stored at 4°C.
