CJC-1295 (Without DAC) 10mg

Name: CJC-1295 (Without DAC) 10mg
Brand: Quanta Pharmaceuticals

Mod GRF 1-29, a short-acting GHRH analogue studied for natural, pulsatile growth hormone release.

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). Four amino-acid substitutions protect it from rapid enzymatic degradation, extending its half-life to roughly 30 minutes compared to just a few minutes for native GHRH. Independent lab testing confirmed the finished vial at 99% purity with an actual content of 10.74mg against the 10mg label claim.

Research Benefits

Pulsatile GH release — Researched for promoting natural, pulsatile growth hormone release rather than a sustained flatline.
Preserves feedback loops — A short half-life leaves endogenous somatostatin and IGF-1 feedback intact, avoiding receptor desensitisation.
Body composition — Investigated for effects on lean mass and fat metabolism, particularly when paired with a GHRP.
Recovery support — Studied for potential acceleration of tissue repair and regeneration.
Sleep quality — Shows effects on deep sleep phases, when natural nocturnal GH pulses peak.

How It Works

CJC-1295 Without DAC binds 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 from somatostatin and IGF-1.

This is the key distinction from the DAC variant, which binds serum albumin to produce a sustained GH elevation over several days rather than a single physiological pulse. Researchers studying natural pulsatile GH release, or stacking with a GHRP such as Ipamorelin, typically favour the Without DAC version for this reason.
