What this does
The stocked blend is 10 mg total: 5 mg CJC-1295 and 5 mg ipamorelin. In 2 mL that is 5 mg/mL of blend, or 2.5 mg/mL of each. A draw delivering 100 mcg of ipamorelin delivers 100 mcg of CJC-1295 with it, because the ratio is fixed.
The vial size above is the one Peptriva ships, read from the live listing. Change it if yours differs. The dose stays whatever you set — this tool does not suggest one.
What is in a CJC-1295 and ipamorelin vial?
The stocked vial is 10 mg co-lyophilized as 5 mg CJC-1295 plus 5 mg ipamorelin, a 1:1 ratio set at manufacture.
One thing to settle before any arithmetic: whether your CJC-1295 is the DAC or no-DAC form. They behave completely differently — the no-DAC form pulses, the DAC form does not — and blends are usually the no-DAC version. The CJC-1295 guide covers the difference.
The 10 mg total at four water volumes:
| Water added | Concentration | Units for a 1 mg draw |
|---|---|---|
| 1 mL | 10 mg/mL | 10.0 units |
| 2 mL | 5 mg/mL | 20.0 units |
| 3 mL | 3.33333 mg/mL | 30.0 units |
| 5 mL | 2 mg/mL | 50.0 units |
Those are TOTAL concentrations. Halve each for the per-compound figure: at 2 mL the vial is 5 mg/mL of blend and 2.5 mg/mL of each compound.
What has been studied
Ipamorelin reached a Phase III trial, in postoperative ileus, and missed its endpoint. Development stopped there. Zero randomized trials cover muscle, fat, aging or recovery — the reasons this blend is actually bought.
CJC-1295 has published pharmacokinetic work in healthy adults showing dose-dependent rises in GH and IGF-1, which is a hormone response rather than an outcome. The combined dosage page sets out what each study administered, and ipamorelin before and after covers the failed trial in detail.
CJC-1295 vs ipamorelin covers why the two are combined at all.
The trap on this one: micrograms against a milligram vial
1 mg = 1,000 mcg. This blend is labeled in milligrams and dosed in micrograms, and the per-compound halving sits on top of that. Two conversions in one calculation is why this vial produces more arithmetic errors than any other.
Work it in one direction. Pick the compound you are targeting, set its dose with the unit selected explicitly, and remember the concentration for that compound is half the blend concentration. Then check what the same draw delivers of the other one.
Both compounds are prohibited in sport under WADA S2, which a calculator cannot tell you and which matters more than the arithmetic for anyone tested. CJC-1295 side effects covers the rest.
Frequently asked questions
How many units is 100 mcg of ipamorelin from a 10 mg blend vial?
At 10 mg in 2 mL the blend is 5 mg/mL, which is 2.5 mg/mL of ipamorelin. 100 mcg is 0.04 mL — 4 units on a U-100 syringe. That same draw delivers 100 mcg of CJC-1295 as well.
How much water for a 10 mg CJC-1295 ipamorelin vial?
Your choice. 2 mL gives 5 mg/mL of blend and 2.5 mg/mL of each compound. More water makes the draw larger and easier to measure, which helps here because the doses are small.
Is the concentration per compound or total?
The tool works from the total in the vial. For a 1:1 blend, halve the result for the per-compound concentration. That halving is the step most often missed.
What dose has been studied?
Nothing for the uses this blend is bought for. Ipamorelin's one Phase III trial was in postoperative ileus and missed its endpoint. CJC-1295 has pharmacokinetic data showing GH and IGF-1 rises, which is a hormone response rather than an outcome.
