How do I reconstitute a 2 mg CJC-1295 (no DAC) vial?

Updated 2026-05-05

Add 2 mL of bacteriostatic water to a 2 mg CJC-1295 (no DAC) vial. That gives you 1 mg per mL. On a U-100 insulin syringe, 10 units equals 100 mcg of CJC-1295. A common starter dose is 100 mcg once a day before bed. CJC-1295 without DAC has a short half-life, so it is dosed daily, not weekly. Pour water down the wall, swirl gently, refrigerate.

IfIf your dose is 100 mcg
Thenthen draw 10 units on a U-100 insulin syringe
IfIf you stack CJC-1295 with ipamorelin
Thenthen draw each peptide into its own syringe and inject in the same site - do not mix them in one vial
IfIf you bought CJC-1295 with DAC instead
Thenthen the math is the same but the dose schedule is once or twice a week, not daily
IfIf the powder is still floating
Thenthen swirl gently or let it sit 2 minutes - shaking can damage the peptide
Key facts
  • 2 mg vial + 2.0 mL bac water = 1 mg/mL concentration
  • On a U-100 syringe at 1 mg/mL, 1 unit = 10 mcg
  • CJC-1295 without DAC has a half-life of about 30 minutes; dose daily before bed for the natural growth-hormone pulse
  • Common pairing is 100 mcg CJC-1295 + 100-300 mcg ipamorelin once nightly
  • Mixed vial keeps in the fridge ~28 days
