Common vial sizes and water amounts
| Vial | Water | What that gives you |
|---|---|---|
| 5 mg | 1 mL | 5 mg/mL; 300 mcg = 6U |
| 10 mg | 2 mL | 5 mg/mL; 300 mcg = 6U |
| 10 mg | 3 mL | 3.33 mg/mL; 300 mcg = 9U |
| 20 mg | 4 mL | 5 mg/mL; 500 mcg = 10U |
Worked examples
Concentration 5 mg/mL → 50 mcg per unit → draw 6 units (0.06 mL) on a 30U syringe. That vial holds about 33.3 such draws.
Concentration 3.33 mg/mL → 33.3 mcg per unit → draw 9 units (0.09 mL) on a 30U syringe. That vial holds about 33.3 such draws.
Concentration 5 mg/mL → 50 mcg per unit → draw 10 units (0.1 mL) on a 30U syringe. That vial holds about 40 such draws.
Notes for this calculator
Blend entries are often small relative to the vial, so a 10 mg vial can hold more than 30 draws. Adding more water (3 mL instead of 2) raises a 300 mcg entry from 6 units to 9, which is easier to read on a 30U syringe.
If your vial lists the two peptides separately (for example 5 mg CJC-1295 and 5 mg Ipamorelin), add them and enter the total; the ratio is fixed inside the vial.

Common questions
How do I calculate a CJC-1295 Ipamorelin blend dose?
Enter the vial's total mg and your water. 10 mg in 2 mL is 5 mg/mL, 50 mcg per unit, so a 300 mcg entry is 6 units. Each unit contains both peptides.
How much water for a 10 mg CJC Ipamorelin vial?
2 mL gives 50 mcg per unit; 3 mL gives about 33 mcg per unit and a larger, easier draw.
How many draws are in a 10 mg blend vial?
10,000 mcg divided by your entry: 300 mcg gives about 33 draws, 500 mcg gives 20.
Does the calculator recommend a dose?
No. You enter the dose your protocol calls for and it converts that into syringe units, mL, and doses per vial. It never suggests what to take.
Why is my draw too big for the syringe?
The concentration is low for that dose. Either use a larger U-100 syringe or mix the next vial with less water. The calculator shows the exact water amount that would fit your syringe.
