CJC-1295 (DAC) calculator
CJC-1295 with DAC is a GHRH analog that binds to albumin and lasts about 6 to 8 days, so one weekly shot raises GH and IGF-1 for the whole week. A 2006 trial in healthy adults used single doses of 30 to 60 mcg/kg, roughly 2 to 4 mg, and saw GH rise 2 to 10 times for 6 days and IGF-1 stay up for 9 to 11 days.

About the CJC-1295 (DAC) math
CJC-1295 with DAC is the version of CJC-1295 that carries the drug affinity complex modification. It is listed as a lyophilized powder in 2 mg and 5 mg vials, smaller than most peptide vials. With a 1 mg example draw, the concentration choice decides whether one draw fills half a syringe or all of it. A 2 mg vial with 1 mL of bacteriostatic water is 2 mg/mL, or 2,000 mcg/mL. A 1 mg draw is then 0.5 mL, or 50 units on a U-100 syringe, and the vial holds exactly two draws. Add 2 mL to the same vial and the concentration drops to 1 mg/mL, so 1 mg is a full 1 mL, or 100 units, the whole barrel of a 1 mL syringe. A 5 mg vial with 2.5 mL is 2 mg/mL again, 50 units per 1 mg and five draws per vial, while 5 mg in 2 mL is 2.5 mg/mL and 1 mg becomes 0.4 mL, or 40 units. Smaller draws scale down the same way: 500 mcg at 2 mg/mL is 25 units.
CJC-1295 (DAC) questions
How much CJC-1295 DAC should I take per week?
The commonly reported dose is 1 to 2 mg once a week. The 2006 trial's best tolerated single doses were 30 to 60 mcg/kg, which is 2 to 4 mg for a 70 kg adult, so 2 mg sits at the low end of what was tested. On a 2 mg vial in 1 mL, 1 mg is 50 units.
How long does CJC-1295 DAC stay in your system?
The trial estimated a half-life of 5.8 to 8.1 days, with GH raised for about 6 days and IGF-1 for 9 to 11 days after one dose. After repeated weekly doses IGF-1 stayed above baseline for up to 28 days. That is why it is a once-a-week peptide.
How many units is 1 mg of CJC-1295 DAC at 2 mg in 1 mL?
2 mg divided by 1 mL is 2 mg/mL. 1 mg divided by 2 mg/mL is 0.5 mL. On a U-100 syringe 0.5 mL is 50 units, and the vial holds two such draws.
How much bacteriostatic water for a 5 mg vial of CJC-1295 DAC?
Any volume the vial holds. 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL and 3 mL gives 1.67 mg/mL (rounded). A 1 mg draw is 20 units, 40 units or 60 units at those concentrations.
How many 500 mcg draws are in a 2 mg vial of CJC-1295 DAC?
2 mg is 2,000 mcg, and 2,000 divided by 500 is 4 draws. With 1 mL of solvent (2 mg/mL) each 500 mcg draw is 0.25 mL, or 25 units.
