CJC-1295 dosage calculator.
Working out a CJC-1295 draw? Enter the mg in the vial, the bacteriostatic water you add, and your target dose in micrograms. You get the exact concentration, the volume to draw in mL, and the units on a U-100 syringe. No rounding, no account, and the full math is shown every time.

How the math works
Three steps, no hand-waving.
Reconstitution is simple arithmetic. The only thing that matters is that it is exact, and that you can see every step.
Vial mg ÷ BAC water mL = mg/mL. A 5 mg vial in 2 mL of water is 2.5000 mg/mL.
Target dose ÷ concentration = mL to draw. 100 mcg ÷ 2.5000 mg/mL = 0.0400 mL.
Draw mL × 100 = units on a U-100 insulin syringe. 0.0400 mL = 4 units.
Background
What CJC-1295 reconstitution is
CJC-1295 is a synthetic analog of growth-hormone-releasing hormone (GHRH), supplied as a lyophilized powder that is reconstituted with bacteriostatic water before a dose can be drawn. It comes in two forms: with DAC (Drug Affinity Complex), which binds albumin and extends the half-life to roughly 6-8 days, and without DAC (often labeled mod GRF 1-29), which is short-acting. The reconstitution math is identical for both: concentration is the mg in the vial divided by the mL of water you add. Because typical doses are in the low microgram range, the calculator shows every decimal so the draw is exact.

FAQ
CJC-1295 reconstitution questions, answered.
How do you calculate a CJC-1295 dose?
Divide the mg of CJC-1295 in the vial by the mL of bacteriostatic water you add to get the concentration in mg/mL. Convert your target dose to mg (1000 mcg = 1 mg), divide by the concentration for the draw volume in mL, then multiply by 100 for units on a U-100 insulin syringe.
How much BAC water for a 5mg CJC-1295 vial?
There is no single right answer. 2 mL gives 2.5 mg/mL; 1 mL gives 5 mg/mL and a smaller draw. Enter the amount you plan to add and the calculator returns your exact draw volume and units for any target dose.
How many units is 100 mcg of CJC-1295?
It depends on the concentration. At 2.5 mg/mL (a 5 mg vial in 2 mL), 100 mcg is 0.0400 mL, or 4 units on a U-100 syringe. Change any input above to see your own numbers.
What is the difference between CJC-1295 with DAC and without DAC?
With DAC, the molecule includes a Drug Affinity Complex that binds to albumin and extends the half-life to about 6-8 days. Without DAC (often sold as mod GRF 1-29) it is short-acting, cleared in minutes. The reconstitution arithmetic is the same for both; only the dosing frequency differs, which is a clinical decision, not a calculator one.
Why is CJC-1295 dosed in micrograms?
Typical research doses are in the tens-to-hundreds of micrograms, far smaller than a milligram. 1 mg equals 1000 mcg. The calculator converts mcg to mg before solving so you can enter whichever unit your protocol uses.
How is CJC-1295 different from ipamorelin?
CJC-1295 is a GHRH analog; ipamorelin is a ghrelin-receptor agonist (a growth-hormone secretagogue). They act on different receptors and are sometimes combined. For reconstitution, both are handled identically: vial mg, mL of water, target dose.
How should reconstituted CJC-1295 be stored?
Follow the storage guidance for your specific product. Reconstituted peptide vials are generally refrigerated and used within a limited window. Regimio tracks a per-vial expiry countdown so you are not guessing how many days are left.
Is CJC-1295 FDA approved?
No. CJC-1295 is a research peptide and is not approved by the FDA for any use. This tool performs arithmetic only and is not a recommendation to use it.
Is this calculator exact?
Yes. It performs the arithmetic with no hidden rounding and shows the concentration to four decimal places, so the draw volume and units are precise.
Is this medical advice?
No. This calculator performs arithmetic on the values you enter. It does not recommend a dose, schedule, or source. Confirm anything you do with a qualified provider.
