CJC-1295 No DAC (10mg)
CJC no DAC
CJC-1295 (no DAC) is a growth hormone-releasing hormone (GHRH) analog that stimulates the pituitary gland to naturally produce more growth hormone. Unlike synthetic HGH, it works with the subject’s own rhythms to support recovery, body composition, and vitality.
The Science
What is CJC-1295 No DAC?
CJC-1295 (no DAC), also known as Modified GRF (1-29) or Mod GRF, is a synthetic analog of growth hormone-releasing hormone (GHRH). It signals the pituitary gland to produce and release more growth hormone naturally, rather than introducing synthetic HGH from outside the body.
The “no DAC” version has a short half-life of approximately 30 minutes, which preserves the body’s natural pulsatile pattern of GH release. This is important because growth hormone is normally released in pulses, not continuously—and maintaining this rhythm may reduce the risk of receptor desensitization.
Clinical studies showed that GHRH analogs like CJC-1295 can increase GH levels by 2-10 fold and IGF-1 levels by 1.5-3 fold. It’s often combined with a growth hormone secretagogue like Ipamorelin for synergistic effects—the GHRH analog amplifies the signal while the secretagogue triggers the release.
Mechanism of Action
The GHRH Pathway
CJC-1295 works by mimicking the subject’s natural growth hormone-releasing hormone, stimulating the pituitary to produce more GH on its own.
GHRH Receptor Activation
Binds to GHRH receptors on pituitary somatotroph cells, signaling them to synthesize and release growth hormone into circulation.
Pulsatile GH Release
The short half-life (~30 min) allows GH to be released in natural pulses rather than sustained elevation, preserving physiologic rhythm.
IGF-1 Production
Elevated GH stimulates the liver to produce IGF-1, which mediates many of growth hormone’s anabolic and regenerative effects throughout the body.
Natural GH Stimulation
Signals the pituitary to produce its own growth hormone rather than introducing synthetic HGH—working with the subject’s natural systems.
Improved Recovery
Enhanced GH and IGF-1 levels support tissue repair, muscle recovery after exercise, and overall healing processes.
Body Composition
Growth hormone optimization may support increased lean muscle mass and reduced body fat when combined with proper nutrition and exercise.
Better Sleep Quality
GH is naturally released during deep sleep.
Synergy with Secretagogues
Often combined with Ipamorelin or other GH secretagogues for enhanced effects—the GHRH analog amplifies what the secretagogue triggers.
Anti-Aging Support
GH and IGF-1 decline with age. Restoring more youthful levels may support skin health, energy, cognitive function, and overall vitality.
FAQ
Frequently Asked Questions
How is CJC-1295 different from synthetic HGH?+
CJC-1295 stimulates the pituitary gland to produce its own growth hormone, while synthetic HGH (somatropin) introduces external growth hormone directly. The GHRH analog approach is considered more physiologic because it works through the body’s natural feedback systems and preserves pulsatile release patterns.
Why is CJC-1295 often combined with Ipamorelin?+
CJC-1295 (a GHRH analog) and Ipamorelin (a growth hormone secretagogue) work through different mechanisms that complement each other. The GHRH analog amplifies the GH-releasing signal, while the secretagogue triggers the actual release. Together, they can produce greater GH elevation than either alone—this is called synergy.
When do results appear in CJC-1295 studies?+
Results vary by individual, but potential benefits include improved recovery from exercise, better sleep quality, positive changes in body composition (more lean mass, less fat), improved skin quality, and enhanced overall vitality. Clinical studies showed 2-10x increases in GH levels and 1.5-3x increases in IGF-1. Results typically develop over weeks to months of consistent use.
