CJC-1295 NO DAC is a peptide supplement that works to stimulate the release of growth hormone (GH) from the pituitary gland. CJC-1295 is considered unique due to the covalent addition of a maleimidopropionic acid group to the C-terminus of the peptide. The covalent attachment allows it to bind to proteins in the plasma such as serum albumin. Additionally, with the covalent conjugation of molecules, the peptide has a much longer half-life than it would without the bond.
