Quanta Pharma CJC-1295 (Without DAC) Specifications

Research Benefits

• ✓Pulsatile GH release : Researched for promoting natural, pulsatile growth hormone release from the pituitary rather than creating a sustained flatline
• ✓Preserves natural feedback loops : Short half-life means endogenous somatostatin and IGF-1 feedback remain intact, avoiding receptor desensitisation
• ✓Body composition : Investigated for effects on lean muscle mass and fat metabolism in research models, particularly when paired with a GHRP
• ✓Recovery enhancement : Demonstrates potential for accelerating tissue repair and regeneration
• ✓Sleep quality : Shows effects on deep sleep phases, which is when natural nocturnal GH pulses peak
• ✓GHRP stack synergy : The classic research pairing is CJC-1295 (No DAC) with Ipamorelin, where the two peptides act on different receptors to amplify GH release

How Quanta Pharma CJC-1295 (Without DAC) Works

CJC-1295 without DAC , properly known as Modified GRF 1-29 , is a synthetic analogue of the first 29 amino acids of growth hormone releasing hormone (GHRH) , the endogenous peptide that stimulates GH secretion from the anterior pituitary. Four specific amino acid substitutions at positions 2, 8, 15, and 27 protect the peptide from rapid enzymatic degradation, particularly by the enzyme dipeptidyl peptidase-4 (DPP-4), extending its half-life to around 30 minutes compared to just a few minutes for native GHRH.

Research indicates Quanta Pharma CJC-1295 (Without DAC) works by binding to GHRH receptors on pituitary somatotroph cells, triggering a clean, short pulse of growth hormone release that mimics the body’s own natural secretion pattern. Because the peptide clears within about half an hour, it does not override the pituitary’s native pulsatile rhythm or the negative feedback regulation from somatostatin and IGF-1, both of which are important for avoiding receptor desensitisation.

This is the key distinction from the DAC version: CJC-1295 with DAC produces a sustained “bleed” of GH over several days, whereas CJC-1295 Without DAC produces a single physiological pulse. Researchers who specifically want to study or replicate natural pulsatile GH release, or who want to stack with a GHRP like Ipamorelin, typically choose the No DAC version.

Quanta Pharma CJC-1295 Without DAC vs With DAC

The two variants of CJC-1295 behave very differently in research. Quanta Pharma CJC-1295 Without DAC (Mod GRF 1-29) has a half-life of approximately 30 minutes and produces short, clean GH pulses that mirror natural physiology, requiring more frequent dosing but preserving the body’s native feedback loops. The DAC version, by contrast, incorporates a Drug Affinity Complex that binds it to serum albumin, extending its half-life to roughly 6 to 8 days and producing a sustained elevation in GH levels. Many researchers prefer the Without DAC version for stacking with GHRPs like Ipamorelin, as the short-acting profile allows for precisely timed, pulsatile GH release rather than a constant bleed.
