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.
