What it is

CJC-1295 with DAC is a long-acting GHRH analog studied for longer GH and IGF-1 exposure from one or two injections per week.

Evidence boundary

Investigational / limited human evidence.

Titration rules

  • Titration schedule (1–2× weekly):

  • Weeks 1–2 (titration): 300 mcg per dose.

  • Weeks 3–4: 500 mcg per dose.

  • Weeks 5–6: 750 mcg per dose.

  • Weeks 7–12 (target): 1.0 mg per dose, 1–2× weekly.

  • Timing: Day-of-week is flexible because of the long half-life. A common protocol dose Sunday/Wednesday or Monday/Thursday for the twice-weekly schedule.

  • GH and IGF-1 response

  • Fluid retention

  • Tingling or carpal-tunnel-like symptoms

  • Headache

Practical rules

  • Dose on a consistent day pattern only if a clinician has a reason.
  • Monitor glucose periodically.
  • Keep sleep and training steady.
  • Rotate sites.
