CJC-1295 Dosage Calculator: Reconstitution and Units

To calculate CJC-1295 dosage, divide your target dose (mg) by the vial concentration. Concentration = vial mg ÷ BAC water mL. For a 2 mg vial with 2 mL BAC water: concentration is 1 mg/mL. A 0.1 mg (100 mcg) dose equals 0.1 mL (10 U-100 units) on a standard insulin syringe.

How to Calculate CJC-1295 Dosage

Three steps convert any vial and BAC water combination into the exact volume to draw on a U-100 insulin syringe.

  1. Step 1 — Calculate concentration (mg/mL)

    Divide the total peptide in the vial (mg) by the volume of BAC water you added (mL). For example: a 5 mg CJC-1295 vial reconstituted with 2 mL BAC water gives 5 ÷ 2 = 2.5 mg/mL.

  2. Step 2 — Calculate draw volume (mL)

    Divide your target dose (mg) by the concentration (mg/mL). For a 0.5 mg dose at 2.5 mg/mL: 0.5 ÷ 2.5 = 0.2 mL. This is the exact volume to draw into the syringe.

  3. Step 3 — Convert to U-100 syringe units

    Multiply the draw volume (mL) by 100. For 0.2 mL: 0.2 × 100 = 20 U-100 units. Read this number on the unit markings of a standard insulin syringe.

Dosage Formula

Concentration formula

Concentration (mg/mL) = Vial mg ÷ BAC water mL

Draw volume formula

Draw volume (mL) = Dose (mg) ÷ Concentration (mg/mL)

U-100 syringe units

U-100 units = Draw volume (mL) × 100

These three formulas apply to any CJC-1295 vial, regardless of size. U-100 is the standard insulin-syringe scale: 100 units = 1 mL.

Example CJC-1295 Calculations

Step-by-step worked examples using common vial sizes. Results are for illustrating the math only.

2 mg vial + 2 mL BAC water, 300 mcg (0.3 mg) dose

  1. Vial: 2 mg  |  BAC water: 2 mL  |  Target dose: 0.3 mg
  2. Concentration: 2 ÷ 2 = 1 mg/mL
  3. Draw volume: 0.3 ÷ 1 = 0.3 mL
  4. U-100 units: 0.3 × 100 = 30 units

5 mg vial + 2 mL BAC water, 300 mcg (0.3 mg) dose

  1. Vial: 5 mg  |  BAC water: 2 mL  |  Target dose: 0.3 mg
  2. Concentration: 5 ÷ 2 = 2.5 mg/mL
  3. Draw volume: 0.3 ÷ 2.5 = 0.12 mL
  4. U-100 units: 0.12 × 100 = 12 units

CJC-1295 Reconstitution Guide

CJC-1295 comes in 2 mg or 5 mg vials. Reconstitute with BAC water:

  1. Swab both stoppers with alcohol.
  2. Inject BAC water slowly along the vial wall.
  3. Gently swirl until dissolved. Do not shake.
  4. Store at 2–8 °C. Use within 4 weeks.

CJC-1295 doses are typically expressed in mcg. Convert: 100 mcg = 0.1 mg, 300 mcg = 0.3 mg. Enter the mg value in the calculator.

Frequently Asked Questions

How do I calculate CJC-1295 draw volume?

Divide your dose (mg) by the concentration. For 2 mg + 2 mL BAC: 1 mg/mL. For 0.3 mg: 0.3 ÷ 1 = 0.3 mL = 30 U-100 units.

What are U-100 syringe units?

U-100 is the standard scale for insulin syringes. 100 units = 1.0 mL. That means 10 units = 0.1 mL, 50 units = 0.5 mL. Multiply any draw volume in mL by 100 to get the U-100 units reading.

How do I convert mcg to mg for the calculator?

Divide mcg by 1000 to get mg. For example: 250 mcg = 0.25 mg, 500 mcg = 0.5 mg, 1000 mcg = 1 mg. Enter the mg value in the calculator.

Do I need to recalculate if I change the amount of BAC water?

Yes. Changing BAC water volume changes the concentration (mg/mL), which changes the draw volume for the same mg dose. Always recalculate using: concentration = vial mg ÷ BAC water mL, then draw volume = dose mg ÷ concentration.

What is the difference between CJC-1295 with and without DAC?

CJC-1295 with DAC (Drug Affinity Complex) has a much longer half-life (days to a week) compared to CJC-1295 without DAC (also called Mod GRF 1-29), which has a shorter half-life of 30–60 minutes. The reconstitution math is identical — only the dosing frequency differs.
