CJC-1295 is a synthetic growth hormone-releasing hormone (GHRH) composed of 29 key amino acids. The formula binds permanently to liver cell proteins and has the power to stimulate growth hormone levels in adults. Long-acting, the formula has been proven to increase the peaks and valleys of GH secretion and IGF-I production. One week after taking CJC-1295, growth hormone levels in healthy 20- to 40-year-old men increased, as did overall GH and IGF-I secretion levels.. (5) In this same study, the 50% increase in these levels did not result in adverse effects (excessive levels of GH) due to a protective feedback mechanism.. (5)
