CJC-1295 DAC Reconstitution & Dosing
Quick answer: mix a 2 mg vial of CJC-1295 DAC with 2 ml of bacteriostatic water. That gives 1.00 mg/ml, so a typical 2 mg dose is 200 units on a U-100 insulin syringe — about 1 doses per vial. Reported protocols range 1 mg–2 mg, 1–2x weekly.
CJC-1295 with DAC has a drug-affinity complex that extends its half-life to about a week, producing a sustained GH elevation ('GH bleed') rather than pulses — which is why it is dosed weekly instead of daily. Full overview: what is CJC-1295 DAC? →
