CJC-1295 with DAC is a synthetic peptide, analog of the growth hormone-releasing hormone. Though CJC-1295 without DAC has the same effect and stimulates the production and secretion of growth hormone, the addition of Drug Affinity Complex (DAC) is what increases its half-life allowing it to act longer and more potently.
Research in animals also suggests that CJC-1295 with DAC stimulates insulin-like growth factor 1 (IGF-1) and plays a part in a number of physiological processes.
