CJC-1295 / ipamorelin 5 mg reconstitution calculator
How much bac water for CJC-1295 / ipamorelin 5 mg?
There’s no single right amount: the water sets the strength, not how much CJC-1295 / ipamorelin is in the vial, so use the volume on your pharmacy’s instructions. For example, 1 mL makes 5 mg/mL and 2 mL makes 2.5 mg/mL; the table below shows what each volume means on a U-100 syringe.

The volume printed on the vial or its box, not the mg. We’ll tell you if the water won’t fit.
What each volume makes
| Water | Strength | Each unit | 1 mg is |
|---|---|---|---|
| 1 mL | 5 mg/mL | 50 mcg | 20 units |
| 2 mL | 2.5 mg/mL | 25 mcg | 40 units |
| 2.5 mL | 2 mg/mL | 20 mcg | 50 units |
Examples; use the volume on your pharmacy’s instructions. Units are on a U-100 syringe: 100 units = 1 mL.
About the 5 mg vial
5 mg in total, or 5 mg of each?
A blend label may give one total for the vial or a separate mg for each peptide. If yours reads 5 mg in total, this page fits it as it is: with 2 mL, each unit holds 25 mcg of the two peptides together, split between them as your label says. If it lists 5 mg of CJC-1295 and 5 mg of ipamorelin, the vial holds 10 mg, and every figure here is half the real amount. Use the 10 mg vial page for the total, or the blend calculator to see each peptide per unit: with 2 mL, that vial holds 25 mcg of each per unit, 50 mcg in all.
With or without DAC changes the molecule, not the math
“CJC-1295” on a label can mean two different molecules. CJC-1295 with DAC carries a group that binds to albumin in the blood; in healthy adults its estimated half-life was 5.8 to 8.1 days (Teichman et al., 2006). CJC-1295 without DAC, also called Mod GRF 1-29, lacks that group and remains essentially uncharacterized in peer-reviewed human studies (Dominikowski et al., 2026). Mixing either is the same arithmetic: the mg in the vial divided by the mL of water. They aren’t interchangeable, though, so check which one your label names and never swap one for the other on the same instructions.
No approved version, and little evidence for the pair
No FDA-approved product contains CJC-1295 or ipamorelin, alone or blended. The nomination to use CJC-1295 in compounding was withdrawn, and since September 29, 2023 ipamorelin acetate has been in the FDA’s category 2, substances that may present significant safety risks, for outsourcing facilities (FDA, FDA list). A 2026 review found that pairing ipamorelin with CJC-1295 “is largely driven by anecdotal rationale”, with limited controlled evidence for any added effect (Dominikowski et al., 2026). So nothing official fixes this vial’s 5 mg, its split or its water: the calculator works from your label, and a pharmacist should check it before you mix.

About CJC-1295 / ipamorelin
US regulatory status
Not approved for human use in the US
Neither peptide is approved by the FDA for any use, and no FDA-approved product contains either one, alone or blended. The FDA has cited serious adverse events with CJC-1295, including increased heart rate and a systemic vasodilatory reaction; the nomination to allow it in compounding was withdrawn, and it is on no list that permits compounding. Ipamorelin is in category 2 (significant safety risks) for outsourcing facilities (503B), and its 503A nomination was withdrawn. WADA prohibits both at all times.

How this CJC-1295 / ipamorelin calculator works
This CJC-1295 / ipamorelin reconstitution calculator starts from the 5 mg in your vial. Add the water you mix it with and the dose your prescriber gave you; it divides the mg by the mL to get the strength, then turns your dose into mL and units on a 30, 50 or 100-unit syringe.
Peptinote never suggests a dose or a water volume. The example volumes are there to make the math easy to check, not as advice. For the full method, see the peptide calculator.
Questions people ask
How much bacteriostatic water to mix with 5 mg of CJC-1295?
There’s no single right amount: use the volume on your pharmacy’s instructions. The water only sets the strength; the vial still holds 5 mg however much you add. With 1 mL it’s 5 mg/mL (50 mcg per unit), with 2 mL 2.5 mg/mL (25 mcg per unit) and with 2.5 mL 2 mg/mL (20 mcg per unit). Enter your volume and prescribed dose above to get the units. This product isn’t FDA-approved, so no official label sets a water volume and its contents aren’t verified.
How much bac water for CJC-1295 / ipamorelin?
Whatever volume you add, only the strength changes; the vial still holds 5 mg. More water spreads it out, so each unit holds less and the same dose takes more units: easier to measure, but more liquid to inject. Going from 1 mL to 2.5 mL takes each unit from 50 mcg to 20 mcg. Check the volume on your pharmacy’s instructions first. This product isn’t FDA-approved, so no official label sets a water volume and its contents aren’t verified.
How much bacteriostatic water do I put in CJC / ipamorelin?
Use the volume your pharmacy specifies, and never more than the vial itself can hold (its size in mL, not the 5 mg on the label). If you weren’t given a volume, ask a pharmacist before mixing. For reference, the bac water calculator shows the arithmetic: water (mL) = vial mg × units ÷ (dose mg × 100). This product isn’t FDA-approved, so no official label sets a water volume and its contents aren’t verified.
How do I reconstitute CJC-1295 / ipamorelin 5 mg?
Wipe both stoppers with alcohol and let them dry. Draw the volume of bacteriostatic water your pharmacy specifies into a new syringe, add it slowly down the inside of the vial, then swirl gently until clear; don’t shake. Label it with the strength: 5 mg in 1 mL is 5 mg/mL. Full steps: how to reconstitute peptides.
What are the steps to reconstitute ipamorelin 5 mg?
Mixing your CJC-1295 / ipamorelin 5 mg vial takes the bacteriostatic water your pharmacy specifies and a new sterile syringe. Add the water slowly against the glass and swirl, never shake, until the liquid is clear. If it stays cloudy or has particles, don’t use it; call your pharmacy. Then write the strength and date on the vial and store it as the label says (how to store peptides).
Is there a peptide calculator for CJC-1295 and ipamorelin?
This page is the CJC-1295 / ipamorelin 5 mg reconstitution calculator. Enter the water you add (or tap an example volume) and your prescribed dose, and it shows the units to draw on a 30, 50 or 100-unit syringe, the strength, and the doses in the vial, with every step of the math. It never suggests a dose.
Can Peptinote tell me how many units to take?
No. Peptinote never suggests a dose. Enter the dose your prescriber gave you, and the calculator shows how to measure it: the units, the mL and where the line sits on your syringe, with every step of the math. If you aren’t sure what your dose is, ask your prescriber or pharmacist before drawing anything. How our calculator works.
