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

CJC-1295 without DAC, also known as Modified GRF (1-29) or Mod GRF 1-29, is a synthetic 29-amino-acid peptide analog of growth hormone-releasing hormone (GHRH). The key modifications at positions 2, 8, 15, and 27 protect against enzymatic degradation while maintaining the natural pulsatile pattern of GH release — unlike the DAC version which provides sustained elevation. This makes it preferred by researchers studying physiological GH secretion patterns. Supplied in research-grade and pharmaceutical-grade lyophilized form.
