CJC-1295 is a synthetic analogue of growth hormone releasing hormone (GHRH) that increases plasma levels of growth hormone and insulin-like growth factor 1 (IGF-1).  DAC is an additive moiety that prolongs the plasma half-life of CJC-1295.
 
As a derivative of GHRH, CJC-1295 promotes the release of GH.S tudies show that a single dose of CJC-1295 increase GH levels in mice by 2-10 times. Peak GH levelsare reached approximately 2 hours after administration and the effects last for about six days. Unlikeother GH secretagogues, CJC-1295 preserves normal physiologic release of GH. That means that thenormal circadian peaks and valleys seen in GH release remain intact and that CJC-1295 is a physiologicgrowth hormone releasing factor.
