Enter the milligrams of CJC-1295 in your vial, the bacteriostatic water you added and the CJC-1295 dose in micrograms. You get the mark to draw to, and the same draw carries the ipamorelin in the vial's ratio.
Quick answer: in the common 5 mg + 5 mg blend mixed with 2 ml of bac water, each compound is 2.5 mg/ml, so a draw of 4 units on a U-100 syringe holds 100 mcg of CJC-1295 and 100 mcg of ipamorelin. With 2.5 ml of water the same 100 mcg of each is 5 units. Always calculate from one compound's milligrams, never the blend total.
100 units per ml. Check the barrel — this is what almost every insulin syringe is.

A blend vial holds two peptides dissolved in the same water, so every unit you draw contains both, in the fixed ratio the vial was filled with. You cannot dose them separately from a blend. You pick the mark for one, and the other comes along.
That is why the calculator asks for the CJC-1295 milligrams only. Take a vial labelled “CJC-1295 5 mg / Ipamorelin 5 mg” with 2 ml of water. The CJC-1295 is 5 ÷ 2 = 2.5 mg/ml. A 100 mcg dose of it is 0.1 mg ÷ 2.5 mg/ml = 0.04 ml, which is 4 units. Because the ipamorelin is also 2.5 mg/ml, those 4 units also hold 100 mcg of ipamorelin.
The common mistake is entering 10 mg, the blend total. That halves the units the calculator returns, so the draw holds half of what you intended of each compound. If your label shows a single total figure without the split, find out the split before you mix.
All figures are units on a U-100 insulin syringe. Each dose is the amount of each compound in the draw, for vials that hold equal amounts of both. The doses are a spread chosen to show the arithmetic, not a suggestion of what to use.
| Blend + water | Each conc. | 100 mcg each | 150 mcg each | 200 mcg each | 300 mcg each |
|---|---|---|---|---|---|
| 5 mg + 5 mg, 1 ml | 5 mg/ml | 2u | 3u | 4u | 6u |
| 5 mg + 5 mg, 2 ml | 2.5 mg/ml | 4u | 6u | 8u | 12u |
| 5 mg + 5 mg, 2.5 ml | 2 mg/ml | 5u | 7.5u | 10u | 15u |
| 2 mg + 2 mg, 1 ml | 2 mg/ml | 5u | 7.5u | 10u | 15u |
| 2 mg + 2 mg, 2 ml | 1 mg/ml | 10u | 15u | 20u | 30u |
The 5 mg + 5 mg with 1 ml row shows why so many people add more water: 100 mcg of each is just 2 units, hard to draw accurately on any barrel. The same vial with 2.5 ml puts it on a clean 5. Blends of these two are dosed in micrograms, so the draws are small by nature; the water is your main tool for making them readable.
Not every blend is one-to-one. If a vial holds, say, 2 mg of CJC-1295 and 4 mg of ipamorelin, calculate the units from the CJC-1295 (2 mg) and remember that every draw then carries twice as much ipamorelin. The ratio on the label is fixed; no water volume changes it.
With two separate vials there is no ratio to track. Each vial gets its own water and its own calculation, and each result is the mark for that vial alone. Separate vials take more steps but let the two doses move independently, which a blend never can.
Either way, write both compounds and both concentrations on the vial when you mix it. A blend with a missing label is the hardest vial to recover from, because the ratio is gone along with the concentration.
CJC-1295 is sold in two forms with nearly the same name. The form without DAC is also called Mod GRF 1-29 and is the one usually blended with ipamorelin. The DAC form has an added chemical group that keeps it active for much longer. The calculator works the same for both, because syringe units only care about milligrams and millilitres, but the two are not interchangeable, so check which one your label names.
