CJC-1295
Also known as: CJC-1295 DAC, Modified GRF 1-29
Growth hormone-releasing hormone analog
Mechanism of Action
Stimulates growth hormone release from the pituitary. Often combined with a GHRP for synergistic effects.
66.7% of observational mentions of CJC-1295 (n=78) reference concurrent use with Ipamorelin, making it one of the most stack-dependent peptides in available data. A GHRH analog (also known as CJC-1295 DAC or Modified GRF 1-29), it has no FDA approval for human use. Self-reported outcomes most frequently center on body composition (36.4%), sleep quality (21.8%), and growth hormone effects (20.0%).
Reported Outcomes
Clinical grade reflects published research; Community grade reflects user reports (n=78).
Changes in muscle vs fat ratio
Effects on sleep quality
Effects on growth hormone levels
The provided abstracts classify CJC-1295 as a growth hormone-releasing hormone (GHRH) targeted in anti-doping protocols. The texts focus on analytical detection methods (LC-HRMS/MS) and pharmacokinetics (detection windows) in plasma rather than measuring physiological changes in growth hormone levels.
Changes in energy and fatigue levels
Effects on mood and cognitive function
