CJC-1295 is a synthetic 30-amino acid peptide analog of growth hormone-releasing hormone (GHRH), developed by ConjuChem Biotechnologies. It features four amino acid substitutions from native GHRH (1-29) to improve protease resistance, plus a C-terminal lysine with a maleimidopropionic acid group.
Not FDA-approved; classified as a research chemical. Human studies used 30-60 mcg/kg subcutaneously. Commonly discussed research doses: CJC-1295 without DAC (Mod GRF 1-29) at 100-300 mcg 1-3x daily; CJC-1295 with DAC at 1-2 mg once or twice weekly. Often combined with GHRP peptides like Ipamorelin for synergistic GH release.
Mechanisms of Action
3Benefits
4Increased growth hormone secretion
HormonalA single injection can increase plasma GH levels 2-10x for 6+ days, with preserved pulsatile secretion patterns. Confirmed in human clinical studies.
Improved body composition
Body CompositionElevated GH and IGF-1 support increased lean muscle mass and reduced body fat over time.
Enhanced deep sleep
SleepHigher GHRH activity increases slow-wave (deep) sleep, contributing to better overnight recovery, reduced soreness, and improved mental clarity.
Recovery and tissue repair
RecoveryElevated GH and IGF-1 support faster recovery from exercise and injuries, and promote connective tissue repair.

Supplements that stack with CJC-1295
3Magnesium on Examine
Magnesium supports GH release quality during sleep. Deficiency is common and suppresses slow-wave sleep, which is when Ipamorelin works.
Creatine on Examine
Creatine supports the lean mass gains that GH secretagogues facilitate. Best combined with resistance training.
