CJC-1295 No DAC (also known as Modified GRF 1-29) is a synthetic analogue of growth hormone-releasing hormone (GHRH), consisting of the first 29 amino acids of endogenous GHRH with four amino acid substitutions that confer increased stability and binding affinity.
CJC-1295 No DAC vs CJC-1295 DAC
- CJC-1295 No DAC: Half-life ~30 minutes. Produces pulsatile GH release mimicking natural GH secretion. Preferred for research studying normal GH pulse dynamics.
- CJC-1295 DAC: Extended half-life of ~6–8 days via albumin binding. Produces sustained GH and IGF-1 elevation. For research examining sustained GH elevation.
VITALITY CARTEL supplies both variants.
CJC-1295 Research Background
Growth hormone secretion: Acts on GHRH receptors in the pituitary, stimulating pulsatile GH synthesis and release. Preclinical studies document dose-dependent GH elevation in rodent models.
IGF-1 research: GH elevation leads to downstream IGF-1 production. Research protocols frequently measure IGF-1 as the primary biomarker for GHRH analogue activity.
CJC-1295 + Ipamorelin Stack: The most documented GH secretagogue research stack. CJC-1295 stimulates GH via GHRH receptors; Ipamorelin provides an additive GH stimulus via GHSR-1a. Co-administration studies report synergistic GH elevation greater than either compound alone. Available pre-blended from VITALITY CARTEL.
