The short answer
Mixed with 2 mL of bacteriostatic water, a 2 mg vial of CJC-1295 (no DAC) holds 1 mg/mL. A 100 mcg dose is then 10 units (0.10 mL) on a U-100 insulin syringe, and the vial holds about 20 doses of that size. Taken 1× per day, it lasts about 2.9 weeks.
How much water
The water only sets the strength; the dose and the number of doses in the vial stay the same. Draws are on a U-100 insulin syringe, where 1 unit is 0.01 mL.
| Water added | Strength | Per syringe unit | Draw for 100 mcg |
|---|---|---|---|
| 1 mL | 2 mg/mL | 20 mcg | 5 units (0.05 mL) |
| 2 mL | 1 mg/mL | 10 mcg | 10 units (0.10 mL) |
| 3 mL | 0.6667 mg/mL | 6.7 mcg | 15 units (0.15 mL) |

Draws over 100 units show in mL. Faded values are under 2 units, which is hard to measure. Check that your vial holds the larger volumes.
Where the doses come from
- Community 100 mcg per injection is most cited (range 50–300 mcg), 1–3× daily.
Doses are what labels, trials or community reports reference, not recommendations. CJC-1295 (no DAC)’s page has the cycle, side effects, cautions and sources.
Mixing and storage
- PrepareLet a refrigerated vial come to room temperature, and wipe both stoppers with an alcohol swab.
- Add 2 mLDraw 2 mL of bacteriostatic water and let it run slowly down the inside wall of the vial.
- Swirl, don’t shakeSwirl gently until the powder dissolves and the liquid is clear.
- Label itWrite the date and the strength, 1 mg/mL, on the vial.
Storage: Powder: frozen or refrigerated, dark. Mixed: 2–8 °C, use within about 4 weeks.

Questions
How much water do I add to a 2 mg vial of CJC-1295 (no DAC)?
There’s no single right amount: the water only sets the strength. With 2 mL of bacteriostatic water, a 2 mg vial holds 1 mg/mL. With 1 mL it’s 2 mg/mL; with 3 mL it’s 0.6667 mg/mL. Less liquid makes each dose a smaller draw; more makes small doses easier to measure.
How many units is 100 mcg of CJC-1295 (no DAC)?
With 2 mL in a 2 mg vial, 100 mcg is 10 units (0.10 mL) on a U-100 insulin syringe. With 1 mL, 5 units (0.05 mL); with 3 mL, 15 units (0.15 mL).
How many doses are in a 2 mg vial of CJC-1295 (no DAC)?
About 20 doses of 100 mcg, or 8 of 250 mcg or 6 of 300 mcg. Taken 1× per day at 100 mcg, it lasts about 2.9 weeks.
How long does a mixed vial of CJC-1295 (no DAC) keep?
Powder: frozen or refrigerated, dark. Mixed: 2–8 °C, use within about 4 weeks.
