CJC-1295
How to reconstitute the 5 mg vial and convert any target dose into insulin units. Reconstitution math and unit conversions for the 5 mg and 10 mg vials. CJC-1295 has no validated human dose; the figures shown are community-reported, with the DAC human study cited for reference.

No validated human dose. CJC-1295 is a research-use peptide with no FDA-approved dose. The reconstitution math below is exact measurement — a calculator, not advice. Any usage figures are community-reported and clearly labeled, and none of this is medical advice.
Calculate for your vial
Enter the mg on your CJC-1295 vial, the bacteriostatic water you added, and your target dose — it works out the exact units to draw on a U-100 insulin syringe, for whatever you personally have.

Check the decimal. A misplaced decimal point here is a 10× dosing error. Re-read every number, and confirm your dose with a licensed clinician before you draw.
Educational only — not a dosing recommendation. This tool does the measurement math; it does not tell you what to take. On a U-100 insulin syringe, 100 units = 1 mL.
Personalize by body weight & height
CJC-1295 · tailored to you
Growth-hormone release scales with body size, so bigger people tend to sit toward the higher end. The usual range is about 100–300 mcg; the numbers below estimate that for your weight.

Typical flat community dose: 100 mcg – 300 mcg per injection.
GH response is weight-related in research, but there is no validated per-kg use instruction — this is an anecdotal estimate kept inside the normal ~100–300 mcg range, not a recommendation. Many people just use a flat amount.

1 · Find your dose
Pick what you're using CJC-1295 for and how much bacteriostatic water you added — this pulls out the exact units to draw and how often people report using it.

2 · Reconstitute it cleanly, step by step
How to turn the 5 mg powder into a measured liquid with clean, sterile technique. More water means each insulin unit holds less peptide — easier to measure small amounts accurately.
1Swab the stoppers
Wipe the rubber top of each vial with an alcohol pad and let it air-dry.
2Draw the water
Pull your bacteriostatic water up into the insulin syringe.
3Reconstitute
Inject it slowly down the inside wall of the peptide vial — never straight onto the powder.
4Swirl to dissolve
Gently swirl until the powder fully dissolves into a clear liquid. Never shake.
5Equalize, then draw
To draw a dose: push in an equal amount of air first to equalize the pressure, then pull your dose.

Swab both tops
Wipe the rubber top of the bacteriostatic-water vial and the CJC-1295 vial stopper with a fresh alcohol pad, and let them air-dry. Never touch the needle or the stoppers after wiping.

Draw the water
First pull 2 mL of air into the syringe and inject it into the bacteriostatic-water vial to equalize the pressure, then draw your 2 mL of water back out. Inject it into the CJC-1295 vial down the inside glass wall, not onto the powder.

Swirl, don't shake
Gently swirl the 5 mg vial until the powder fully dissolves into a clear liquid. Never shake — shaking can damage the peptide and foam the solution.

Know your strength
The vial is now 2.5 mg/mL. Each unit on a U-100 syringe holds about 25 mcg.

Re-swab & draw your dose
Wipe the stopper again. With a fresh insulin syringe, pull back 8 units of air and inject it into the vial to equalize the pressure, then draw 8 units (0.08 mL) for a 200 mcg dose.
8 units - 6
Store it right
Keep the mixed vial in the fridge, away from light. Use a new sterile syringe every time, never share, and drop used sharps in a proper container.

4 · Everyday usage
CJC-1295 is a research peptide with no validated human dose, and it comes in two forms (with or without DAC) that are dosed very differently. The pattern below is the community no-DAC convention.
GH support (community, no-DAC)
Community-reported · anecdotalA per-dose pattern people report for the short-acting (no-DAC / modified GRF 1-29) form, often stacked with ipamorelin.
- Reported amount
- 100 mcg–200 mcg≈ 4–8 units @ 2 mL
- Frequency
- 1–2× daily
- Cycle
- ~8–12 weeks (community)
Community-reported and anecdotal. The long-acting DAC form is instead dosed roughly once weekly. A human study of CJC-1295 with DAC used single subcutaneous doses of 30–250 mcg/kg (tolerated particularly at 30–60 mcg/kg; Teichman et al., J Clin Endocrinol Metab 2006;91(3):799–805) — a per-kilogram research dose, not this regimen. Not a recommendation.
Frequently asked questions
How many insulin units is 100 mcg of CJC-1295 from a 5 mg vial?
- Reconstituting a 5 mg vial with 2 mL of bacteriostatic water gives 2.5 mg/mL — about 25 mcg per unit. Drawing 100 mcg is 0.04 mL, or 4 units on a U-100 insulin syringe. This is measurement math, not a dose recommendation.
How many insulin units is 200 mcg of CJC-1295 from a 5 mg vial?
- Reconstituting a 5 mg vial with 2 mL of bacteriostatic water gives 2.5 mg/mL — about 25 mcg per unit. Drawing 200 mcg is 0.08 mL, or 8 units on a U-100 insulin syringe. This is measurement math, not a dose recommendation.
What is the difference between CJC-1295 with and without DAC?
- The DAC (drug affinity complex) version is long-acting and has been studied as a single subcutaneous dose lasting many days (Teichman 2006, JCEM), so it is typically used about once weekly. The no-DAC form (modified GRF 1-29) is short-acting and is community-dosed in smaller amounts one to a few times daily. Neither has a validated human protocol, and CJC-1295 is not FDA-approved.
