CJC-1295 No DAC (Modified GRF 1-29) — 5mg | Pulsatile GHRH Research
CJC-1295 without DAC, also known as Modified GRF 1-29 or Mod GRF 1-29, is a stabilized analogue of the first 29 amino acids of GHRH with four amino acid substitutions that resist enzymatic degradation. Without the DAC modification, it retains a half-life of ~30 minutes — closely mimicking natural GHRH signalling and enabling pulsatile GH research protocols.
Available Format: 5mg lyophilized vial
Reconstitution: Reconstitute with Bacteriostatic Water (BAC Water) for multi-use stability, or Sterile Water for single-use protocols. Store lyophilized vials at 2–8°C.
Key Research Areas
⚡ Pulsatile GH Secretion Research
No DAC CJC-1295 is the preferred GHRH analogue for studying natural pulsatile GH secretion patterns. Research combines it with GHRPs (Ipamorelin, GHRP-2, GHRP-6) to study the synergistic GH amplification between GHRH and GHSR pathways.
💪 GH-IGF1 Axis Studies
Pulsatile GH administration research demonstrates superior IGF-1 signalling quality compared to sustained GH elevation, potentially better preserving receptor sensitivity and physiological signalling dynamics.
🔧 Combination Protocol Research
Widely paired with Ipamorelin or GHRP-2 in research protocols — GHRH amplifies pulse amplitude while GHRP drives pulse initiation, producing synergistic GH release exceeding either compound alone.
