GH Secretion · Reconstitution Calculator

CJC-1295 reconstitution calculator.

GHRH analog that drives pulsatile growth hormone release. Typically stacked with ipamorelin. A 10 mg vial in 2 mL water gives 5 mg/mL — most dose 100–300 mcg, 5×/week.

  4. 4Refrigerate. Use within 4–6 weeks.
★ FAQ

CJC-1295 questions, answered.

CJC-1295 with or without DAC?+

Without DAC (the more common research version) has a half-life of ~30 minutes and produces a sharp GH pulse — good for pre-bed or post-workout dosing. With DAC has a 6–8 day half-life and produces sustained elevated GH baseline. Different goals, different tools.

How often do you inject CJC-1295?+

Without DAC: typically 5 days per week, before bed. With DAC: 1–2× per week is enough to maintain elevated GH baseline.

Why stack CJC-1295 with Ipamorelin?+

They hit different pathways. CJC-1295 is a GHRH analog (pushes more GH per pulse); ipamorelin is a ghrelin mimetic (triggers the pulse). Combined, the pulse is bigger than either alone.
