Use this calculator for CJC-1295 without DAC — also sold as Mod GRF 1-29 — to translate vial strength and BAC water into a precise draw. The reconstitution math is identical to CJC-1295 with DAC; only the dosing schedule differs.
- Common vial examples
- 2 / 5 / 10 mg
- Example dose
- 100 mcg
- Common syringe
- U-100 insulin
- Last reviewed
Storage before and after reconstitution: Lyophilised 2–8°C; reconstituted vial refrigerated and protected from light.
Quick answers: CJC-1295 (no DAC) doses in units
With a 5 mg vial mixed with 2 mL of bacteriostatic water (2.5 mg/mL), on a U-100 insulin syringe:
- How many units is 100 mcg of CJC-1295 (no DAC)?
- 4 units (0.04 mL)
- How many units is 200 mcg of CJC-1295 (no DAC)?
- 8 units (0.08 mL)
- How many units is 300 mcg of CJC-1295 (no DAC)?
- 12 units (0.12 mL)

Quick math example
A 5 mg vial mixed with 2 mL gives 2,500 mcg/mL. A 100 mcg dose is 0.04 mL, which equals 4 units on a U-100 syringe.
CJC-1295 (no DAC) reconstitution reference
U-100 units to draw for each common CJC-1295 (no DAC) dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 100 mcg | 200 mcg | 300 mcg |
|---|---|---|---|---|
| 2 mg | 1 mg/mL | 10 u(0.1 mL) | 20 u(0.2 mL) | 30 u(0.3 mL) |
| 5 mg | 2.5 mg/mL | 4 u(0.04 mL) | 8 u(0.08 mL) | 12 u(0.12 mL) |
| 10 mg | 5 mg/mL | 2 u(0.02 mL) | 4 u(0.04 mL) | 6 u(0.06 mL) |

Looking for CJC-1295 with DAC?
This page is for CJC-1295 without DAC (Mod GRF 1-29), which lasts about 30 minutes and is dosed daily. CJC-1295 with DAC lasts about a week and is dosed weekly in milligram amounts, so it has its own calculator and dosage chart. Check your vial label before you calculate.

How CJC-1295 (no DAC) differs from the DAC version
CJC-1295 without DAC (Mod GRF 1-29) is short-acting and is usually dosed more frequently, while CJC-1295 with DAC is long-acting and dosed less often. The reconstitution math is exactly the same for both — vial mg divided by water volume gives concentration — so the only thing that changes is how often you draw, not how you calculate the draw.
Confirm which version your vial contains before setting a schedule, because the half-life difference is large even though the syringe math is identical.
- No DAC = short-acting (Mod GRF 1-29); with DAC = long-acting
- Identical reconstitution math; different dosing frequency
- Check the label so the schedule matches the compound
CJC-1295 (no DAC) 5 mg vial with 2 mL example
A 5 mg vial mixed with 2 mL gives 2.5 mg/mL, or 2,500 mcg/mL.
A 100 mcg dose is 0.04 mL — just 4 units on a U-100 syringe. A 200 mcg dose is 0.08 mL, or 8 units. Draws this small make a U-100 insulin syringe the practical choice.
- 5 mg / 2 mL = 2.5 mg/mL
- 100 mcg / 2,500 mcg per mL = 0.04 mL = 4 U-100 units
- 200 mcg / 2,500 mcg per mL = 0.08 mL = 8 U-100 units
Keeping very small draws readable
Because typical doses are around 100 mcg, the draw can be only a few units, where a one-unit slip is a large percentage of the dose. Using more bacteriostatic water raises the volume per dose and spreads it across more unit marks.
The same 5 mg vial in 1 mL gives 5,000 mcg/mL, halving a 100 mcg draw to 2 units; reconstituting in 3 mL instead lowers the concentration so the same dose lands on a larger, easier-to-read number of units.
- Small doses = small draws; precision matters more
- More BAC water spreads a dose across more unit marks
- Pick a concentration that puts your usual dose on a clear line
CJC-1295 + Ipamorelin blend vials
Many CJC-1295 vials are sold pre-mixed with ipamorelin, usually 5 mg of each (10 mg total). A blend vial is calculated from its labelled total, not the CJC-1295 share: 10 mg in 2 mL is 5 mg/mL of blend, so 200 mcg of blend (100 mcg of each) is 4 units.
