0.12 mL in the syringe · 25 calculated doses from this amount

12.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.12 milliliters. The draw lands on a syringe line.

Easy to read on this syringe. The calculated volume matches the 12-unit line. No rounding is needed.

5 mg ÷ 3 mL = 1.67 mg/mL
→ 17 mcg/unit · 200 mcg = 0.120 mL = 12.0 units

Can this syringe show the result clearly?

Easy to read on this syringe. 12.0 u is exactly the 12-unit line on a U-100 — no rounding error at all.

Want an easier syringe number?

This setup is already easy to read. Changing the water between 0.5 and 3 mL would not put 200 mcg closer to a line on this U-100 syringe.

Adding more water makes the mixture less concentrated, so the same dose uses more syringe units. It does not change how much peptide is in the vial.

This setup is in the address bar — every input is part of the link.

How to use the calculator

  1. 1

    Enter the amount in the vial

    Use the total mg printed on your CJC-1295 vial.

  2. 2

    Enter the water you added

    Use the amount of water added to that vial, in mL.

  3. 3

    Enter the dose you want to convert

    Choose mg or mcg, then match the result to your syringe.

CJC-1295 is a redesigned copy of the hormone that tells your pituitary to release growth hormone. One version bonds to a protein in your blood, which stretches its life from minutes into days. It is sold for the same wishlist as ipamorelin, and usually stacked with it: muscle, fat loss, recovery and sleep.

The human studies measured one thing, and it was growth hormone in the blood. None of them reported muscle, fat, strength or anything a person would notice. Most material sold under the name is the short-acting molecule, which was never in those studies.

Examples using 5 mg of CJC-1295

Each row uses 5 mg and the liquid volume shown. Dividing the amount by that volume gives the calculated concentration. The rows are arithmetic examples, not alternative product preparations.

The amount, liquid volume and dose shown here are the calculator’s starting example for CJC-1295. Replace them with your own values. Every result in the table is calculated from those inputs.

Drawn from once a week at 200 mcg, a 5 mg vial yields 25 doses — about 25.0 weeks of supply. No storage limit is assigned to this example. Follow the dispensing label for the specific product.

The CJC-1295 version matters before the draw calculation

The calculator converts the vial amount and dose you enter into a liquid volume. It cannot identify whether a product contains CJC-1295 with DAC. The cited human studies used that version; their results do not establish the same schedule for a product without DAC.

Open the mixing details3 notes

Vial strength does not identify the version

DAC is the attached part that binds to albumin, a protein in the blood. A mass printed on a vial does not describe that attachment. The compound name and formulation are separate from the amount used in the calculation.

Matching a listed vial strength to a calculator preset checks the number entered. It does not verify the contents or make different formulations interchangeable.

A trial amount and a weekly total need context

The cited trial amounts were based on body weight. Changing their mass unit does not remove the per-kilogram basis or turn them into one fixed dose for everyone.

The reported-practice row describes a weekly total. The calculator needs the amount in one draw. It does not decide how to split that total or turn the reported schedule into a trial result.

More water changes the draw, not the dose count

This page has one vial-size preset and two water presets. At the default dose, both calculated draws land on a U-100 mark. A different dose can give a different result.

For a fixed vial amount and dose, more water lowers the concentration and increases the liquid in each draw. The calculated dose count stays the same: vial mass divided by dose mass. That count does not tell you how long a mixed vial remains usable.

CJC-1295 evidence depends on which version is meant

The human studies cited here examined long-acting CJC-1295 with DAC, the drug-affinity complex that binds to albumin. They do not establish the same schedule for a product described as CJC-1295 without DAC.

Read the supporting evidence3 supporting notes

Trial schedules included repeated doses

The published work included both single-dose and repeated-dose studies. Researchers measured growth hormone and IGF-I over time. Those hormone measurements do not by themselves establish a muscle-building or weight-loss result.

A weekly total is different from one draw

The reported-practice row gives a total for a week. The tool’s dose field takes the amount in one draw. Dividing a weekly total between injections is a separate schedule decision that the tool does not make.

Body-weight doses retain their original basis

The trial amounts were set per kilogram. A value quoted in that form is not a flat amount for every person. Converting it to another mass unit preserves that weight basis; it does not supply the amount for one draw.

Units to dose at 1.67 mg/mL

Mix 5 mg into 3 mL and one U-100 unit carries 16.7 mcg. The table shows how much peptide is in each numbered syringe line. These are conversion examples, not suggested doses.

How the math works

  1. Concentration — divide the amount entered by the liquid volume used in the calculation: mg ÷ mL = mg/mL. This tells you how many mg are in each mL.
  2. Volume — the dose divided by that concentration: dose ÷ (mg/mL) = mL.
  3. Units — on a U-100 syringe one unit is 0.01 mL, so mL × 100 = units. A U-40 unit is 0.025 mL, so the wrong barrel is a 2.5× error. That is why the calculator asks which one you have.
  4. Rounding gap — the exact draw against the nearest syringe line: |exact − nearest line| ÷ exact × 100 = % difference.

Questions readers ask

How much bacteriostatic water to mix with CJC?

Both offered volumes produce easy-to-read draws. A 5 mg vial becomes 2.5 mg/mL with 2 mL of water or 1.67 mg/mL with 3 mL.

The 200 micrograms the tool opens on draws exactly 8 units at the first and exactly 12 at the second. Whole numbers at every preset is unusual, so the water is not deciding whether you can read the syringe. It decides how much liquid goes under the skin.

How to reconstitute a 5mg vial of CJC-1295?

The strength is 5 divided by the water you added, and nothing later in the process changes it. At 2 mL each U-100 unit carries 25 micrograms. At 3 mL each carries 16.7.

What the vial cannot tell you is which molecule is inside. Two substances ship under this name at the same 5 mg strength. Only the version carrying the drug-affinity arm has a published human study behind it.

How much BAC water to add to CJC-1295 Ipamorelin?

Nothing published tells you, because no trial has ever given CJC-1295 and ipamorelin to a person together. Searches of both registries in August 2026 found no study of the pair. The one record naming both built a drug test for horse blood.

The blend people search for holds 5 mg of each. At 3 mL that is 1.67 mg/mL of each, so one unit carries 16.7 micrograms of both. You set the syringe once and take away whatever ratio the filler chose.

How much bacteriostatic water for 5mg CJC-1295?

The same two volumes, and here the choice only changes how long the mixed vial lasts. At 200 micrograms a draw, a 5 mg vial holds 25 draws either way, because the powder sets that count.

The water changes the liquid per injection: 0.08 mL at 2 mL, 0.12 mL at 3 mL. One thing to know before converting anything here — every quantity in the human papers scales with body weight. A flat microgram figure did not come from them.
