Overview
CJC-1295 DAC is a synthetic peptide analog of growth hormone-releasing hormone (GHRH). It is designed to stimulate the pituitary gland to release growth hormone (GH). The "DAC" component (Drug Affinity Complex) extends the peptide's half-life, allowing for less frequent dosing.
Unlike GHRPs, which also stimulate GH release but through a different mechanism (ghrelin receptor agonism), CJC-1295 DAC acts directly on the pituitary gland. This results in a more sustained, physiological release of GH.
It is primarily researched for its potential to increase muscle mass, reduce body fat, improve sleep, and enhance recovery. It is important to note that research is ongoing, and it is not approved for medical use in many jurisdictions.
Mechanism of Action
CJC-1295 DAC binds to the GHRH receptor on pituitary cells, stimulating the release of growth hormone (GH). The DAC component is a synthetic molecule that binds to albumin in the bloodstream. This binding protects the peptide from degradation and prolongs its half-life.
By extending the half-life of CJC-1295, the DAC allows for a more sustained release of GH over several days. This results in elevated levels of Insulin-like Growth Factor-1 (IGF-1), which mediates many of the effects of growth hormone.
The pulsatile release of GH remains intact, mimicking the natural release patterns of the body. This is different from direct GH administration, which can disrupt the natural GH rhythm.
Key Benefits
- Increased Muscle Mass
- Reduced Body Fat
- Improved Sleep Quality
- Enhanced Recovery
Research & Indications
Research on CJC-1295 DAC has focused on its potential to increase GH and IGF-1 levels in adults. Studies have shown that it can lead to increases in muscle mass, decreases in body fat, and improvements in sleep quality. It has also been investigated for its potential role in treating growth hormone deficiencies.
Several studies have examined the effects of CJC-1295 DAC on GH and IGF-1 levels in healthy adults. These studies generally report significant increases in both hormones following administration. The long-lasting effects of the DAC allow for less frequent dosing compared to shorter-acting GHRH analogs.
It's essential to note that research is ongoing, and more studies are needed to fully understand the long-term effects and potential therapeutic applications of CJC-1295 DAC. It is not currently approved for medical use by regulatory agencies in many regions.
Dosing Protocols
Disclaimer: The following dosing information is for informational purposes only and does not constitute medical advice. Consult with a qualified healthcare professional before using CJC-1295 DAC or any other peptide.
| Goal | Dose | Frequency | Route |
|---|---|---|---|
| Increased GH Levels | 1-2mg | Once weekly | SubQ |
If applicable, include a gradual titration schedule:
| Phase | Daily Dose | Frequency |
|---|---|---|
| Weeks 1-2 | 250mcg | Once daily |
Supplies Needed
For an 8-16 week protocol:
- Peptide Vials: 2-4 vials of 2mg each
- Insulin Syringes (U-100): 3-6 per week, 24-96 total
- Bacteriostatic Water: 1-2 × 10mL bottles
- Alcohol Swabs: One for vial + one for injection site daily
Side Effects & Safety
Common side effects may include injection site reactions (redness, pain, itching), temporary flushing, and headaches. Some individuals may experience water retention or joint pain. It is important to start with a low dose and gradually increase it to assess tolerance.
CJC-1295 DAC is generally considered safe when used at recommended doses, but long-term safety data is limited. Individuals with a history of cancer or other serious medical conditions should avoid using it. It is also not recommended for pregnant or breastfeeding women.
Consult with a healthcare professional before using CJC-1295 DAC to ensure it is appropriate for you and to discuss any potential risks or interactions with other medications.
Storage & Handling
Store lyophilized (freeze-dried) CJC-1295 DAC vials in a refrigerator at 2-8°C (36-46°F). Protect from light and moisture.
Reconstitute with bacteriostatic water. Once reconstituted, store in the refrigerator and use within 14 days.
