CJC-1295 (no DAC) calculator

CJC-1295 without DAC is modified GRF 1-29, a 29 amino acid GHRH analog with a half-life of about 30 minutes. It gives a short GH pulse that mimics the natural one, which is why it is nearly always paired with a GHRP like ipamorelin.

Easy mix
5 mg + 2.5 mL = 2 mg/mL, so 100 mcg = 0.05 mL = 5 units; 200 mcg = 10 units. A 10 mg vial with 5 mL gives the same 2 mg/mL.

About the CJC-1295 (no DAC) math

CJC-1295 without DAC, also listed as Modified GRF 1-29 or Mod GRF, is a synthetic analog of a 29-amino-acid fragment that lacks the drug affinity complex modification. Suppliers list the lyophilized powder in 5 mg and 10 mg vials. The example below uses a 100 mcg step, which shows how small the marks get at higher concentrations. A 5 mg vial with 2 mL of bacteriostatic water is 2.5 mg/mL, or 2,500 mcg/mL, so 100 mcg is 0.04 mL, or 4 units on a U-100 syringe, and the vial holds 50 such draws. A 10 mg vial with 2 mL is 5 mg/mL, so 100 mcg is only 2 units, with 100 draws in the vial. Two units is a hard mark to read, so a 4 mL fill of the 10 mg vial is another option: back to 2.5 mg/mL and 4 units per 100 mcg. A 1 mL fill of the 5 mg vial gives 5 mg/mL, where 100 mcg is again 2 units.

CJC-1295 (no DAC) questions

How much CJC-1295 no DAC should I take?

There is no established human dose. The commonly reported range is 100 to 200 mcg under the skin, one to three times a day, fasted, almost always alongside ipamorelin at the same dose. On a 5 mg vial in 2.5 mL that is 5 to 10 units.

CJC-1295 with DAC or without DAC, which should I use?

No DAC gives a 30 minute pulse and is dosed daily with a GHRP; DAC lasts about a week and is dosed once weekly, with GH raised continuously. Most users who want the natural pulse pattern pick no DAC. The only human trial data is for the DAC version.

How many units is 100 mcg of CJC-1295 no DAC at 5 mg in 2 mL?

5 mg divided by 2 mL is 2.5 mg/mL, which is 2,500 mcg/mL. 100 mcg divided by 2,500 mcg/mL is 0.04 mL. On a U-100 syringe that is 4 units.

How much bacteriostatic water for a 10 mg vial of CJC-1295 no DAC?

Any volume the vial holds. 1 mL gives 10 mg/mL, 2 mL gives 5 mg/mL and 3 mL gives 3.33 mg/mL (rounded). A 100 mcg draw is 1 unit, 2 units or 3 units at those three concentrations.

How many 100 mcg draws are in a 5 mg vial of CJC-1295 no DAC?

5 mg is 5,000 mcg, and 5,000 divided by 100 is 50 draws. The solvent volume does not change that count; it only changes how many units each draw occupies.
