CJC-1295 is a synthetic peptide developed for its ability to promote the secretion of human growth hormone (HGH). It is part of a class of peptides known as growth hormone-releasing hormone (GHRH) analogs. CJC-1295 is primarily used in clinical and performance-enhancing contexts to stimulate the pituitary gland, leading to increased HGH and insulin-like growth factor 1 (IGF-1) production, both of which are associated with various health and longevity benefits.
