Short Intro
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) engineered for enhanced stability and pituitary receptor affinity. It is studied for its ability to stimulate endogenous growth hormone production through the body's natural secretory pathway, producing downstream effects on IGF-1 that are relevant to tissue repair, body composition, and metabolic research.
CJC-1295 At a Glance
| Feature | Description |
|---|---|
| Compound Type | Synthetic GHRH Analog |
| Research Focus | Growth Hormone & IGF-1 Signaling |
| Common Variant | No DAC for shorter pulse activity |
| Longer-Acting Variant | DAC version for extended activity |

What Is CJC-1295?
CJC-1295 is a modified 29-amino acid peptide based on the naturally occurring GHRH sequence. Two primary variants are studied:
- CJC-1295 with DAC (Drug Affinity Complex): The DAC modification allows the peptide to bind to serum albumin, extending its half-life to approximately 6-8 days.
- CJC-1295 No DAC: This version is shorter acting and more closely mimics the body's natural growth hormone pulse pattern.
Both forms are researched for their ability to stimulate growth hormone release and increase IGF-1 signaling through endogenous pathways.
How CJC-1295 Works
GHRH Receptor Activation
CJC-1295 binds to GHRH receptors in the pituitary gland, encouraging the release of growth hormone.
IGF-1 Support
Growth hormone activity can increase downstream IGF-1 signaling, which is frequently studied in relation to recovery, body composition, and tissue repair.
Pulse-Based Activity
CJC-1295 No DAC is commonly paired with Ipamorelin because the combination supports a more natural growth hormone release pattern.
Potential Benefits of CJC-1295
Recovery Support
CJC-1295 is commonly discussed in research protocols focused on recovery, tissue support, and adaptation to physical stress.
Body Composition Research
Because growth hormone and IGF-1 pathways are involved in metabolism and lean tissue support, CJC-1295 is frequently studied in body composition contexts.
Sleep and Repair Pathways
Growth hormone release is naturally connected to deep sleep and overnight recovery, making CJC-1295 relevant to recovery-focused research.
CJC-1295 with DAC vs No DAC
| Variant | Research Profile |
|---|---|
| CJC-1295 with DAC | Longer acting, extended GH/IGF-1 elevation |
| CJC-1295 No DAC | Shorter acting, pulse-like profile |
| Most Common Stack | CJC-1295 No DAC + Ipamorelin |
| Research Preference | No DAC is often preferred when studying natural GH pulsatility |
Common CJC-1295 Stacks
CJC-1295 + Ipamorelin
This is one of the most widely used peptide combinations for growth hormone pulse support.
CJC-1295 + BPC-157
Often discussed in recovery-focused protocols involving soft tissue, connective tissue, and repair research.
CJC-1295 + TB-500
Commonly used in broader recovery stacks where systemic repair and tissue remodeling are being studied.
Dosage Considerations
CJC-1295 protocols vary depending on whether the DAC or No DAC version is being studied.
| Variant | Common Research Range |
|---|---|
| CJC-1295 No DAC | 100-300 mcg per administration |
| CJC-1295 with DAC | Less frequent administration due to longer half-life |
| Common Pairing | 100-300 mcg Ipamorelin |
Storage and Handling
Lyophilized CJC-1295 is generally stored refrigerated and protected from light. After reconstitution, the solution should remain refrigerated and handled using sterile technique.
Conclusion
CJC-1295 remains one of the most recognized peptides in growth hormone research because it acts through endogenous signaling pathways rather than replacing growth hormone directly. Its strongest use case is often in combination with Ipamorelin, especially when studying recovery, sleep, body composition, and IGF-1-related outcomes.
Frequently Asked Questions
What is the difference between CJC-1295 with DAC and No DAC?
The DAC version is longer acting, while the No DAC version has a shorter pulse-like activity pattern.
Can CJC-1295 be stacked with Ipamorelin?
Yes. CJC-1295 No DAC and Ipamorelin are among the most commonly combined growth hormone-supporting peptide stacks.
Is CJC-1295 the same as growth hormone?
No. CJC-1295 stimulates the body's own growth hormone release rather than supplying synthetic growth hormone directly.
What is CJC-1295 most commonly stacked with?
Ipamorelin is the most common pairing, followed by recovery compounds such as BPC-157 and TB-500.
