CJC-1295 / Ipamorelin reconstitution calculator
GHRH + secretagogue combo. Stimulates pulsatile growth hormone release. The 0.5 h half-life reflects the no-DAC ('Mod GRF 1-29') CJC-1295 component (Frohman, J Clin Invest 1986); Ipamorelin itself runs ~2 h (Gobburu, Pharm Res 1999). The DAC variant of CJC-1295 has a half-life of ~6–8 days but is not in this combo. Studied for GH output, sleep quality, and recovery.
