CJC-1295 (no DAC)

CJC-1295 without DAC (Mod-GRF 1-29)

CJC-1295 (no DAC), also known as Modified GRF 1-29, is a synthetic analogue of growth hormone-releasing hormone (GHRH). It carries four targeted amino-acid substitutions that make it more resistant to enzymatic breakdown than the natural fragment, while keeping the same signalling activity. In research, it is studied as a short-acting way to prompt the body's own pituitary gland to release growth hormone in a natural, pulsed rhythm.
