To turn a CJC-1295 vial into syringe units, first find the concentration — vial mg divided by the mL of bacteriostatic water you add — then read units off a U-100 syringe, where 1 unit = 0.01 mL. Example: 5 mg in 2 mL is 2.5 mg/mL, and 0.05 mL of that solution reads 5 units on the syringe. CJC-1295 has no established dose, so you enter your own volume. This is arithmetic only, not medical advice — verify any use with a licensed clinician.

Reconstitution / draw volume / syringe units / supply-chain
Arithmetic checks out. Confirm clinically, against the label, and against the actual vial before any use.
Independent check - dose mg / concentration mg/mL = volume. U-100 units = mL x 100.
Healthy-adult studies examined 30 and 60 mcg/kg among ascending doses; protocol-controlled
Weight-based conversion supported mathematically, but CJC-1295 with DAC must not be confused with 'no-DAC' products.
Limited data; FDA notes serious adverse events including increased heart rate and vasodilatory reaction.
PubMed - PMID 16352683Supply-chain signal only - not a potency guarantee. Enter the COA's tested mg and purity above so the math reflects the real vial.

Same-syringe co-draw. Reconstitute each peptide in its own vial, then draw them into one syringe.
- Reconstitute each peptide in its own vial — never add water to multiple peptides in one vial.
- Only co-draw peptides with the same diluent (e.g. both bacteriostatic water) and compatible pH.
- Draw and inject fresh — do not pre-mix and store; mixture stability is not established.
- No blended stack is clinically validated. Verify each component and confirm with a clinician.
CJC-1295 concentration and syringe-unit conversion chart
| Vial + water | Concentration | Units per 1 mg | Units per 100 mcg |
|---|---|---|---|
| 5 mg + 1 mL | 5 mg/mL | 20 | 2 |
| 5 mg + 2 mL | 2.5 mg/mL | 40 | 4 |
| 5 mg + 3 mL | 1.67 mg/mL | 60 | 6 |
| 10 mg + 1 mL | 10 mg/mL | 10 | 1 |
| 10 mg + 2 mL | 5 mg/mL | 20 | 2 |
| 10 mg + 3 mL | 3.33 mg/mL | 30 | 3 |
Concentration = vial strength divided by the bacteriostatic water added. On a U-100 syringe 100 units = 1 mL, so units = (dose divided by concentration) x 100. Values are syringe units, not milligrams. Amber values exceed 100 units, which is more than one standard 1 mL U-100 syringe holds, so that combination needs a more concentrated solution. The published figures for CJC-1295 are weight-based (30-60 mcg/kg), so they cannot be shown as a fixed milligram column without assuming a body weight, which this site will not do. This chart shows conversion factors only. Multiply the units-per-1-mg figure by your own dose in milligrams to convert any amount. For vial sizes or doses not shown here, use the general mg to units converter.

Frequently asked questions
Can this calculator tell me how much CJC-1295 to inject?
No. It only performs reconstitution arithmetic, converting a vial’s milligram strength and your bacteriostatic water volume into a concentration and a syringe reading. It is not medical advice and does not set a dose. CJC-1295 is investigational and not FDA-approved, so there is no approved self-use dose; discuss any use with a licensed clinician.
Why does the DAC vs no-DAC choice matter before I calculate anything?
It is the defining, safety-relevant distinction for this peptide. CJC-1295 with DAC (Drug Affinity Complex) has a very long half-life, while the “no-DAC” form, essentially modified GRF 1-29, acts over a much shorter window. The two are dosed and timed very differently, so confirm which product your vial actually contains before entering any numbers.
What form did the published CJC-1295 studies actually use?
The healthy-adult work behind this peptide (PMID 16352683) examined the DAC form at roughly 30 and 60 mcg/kg, meaning doses scaled to body weight rather than a single fixed amount. Those figures come from an investigational study among ascending, protocol-controlled doses, not from an approved label, and the tool does not apply them for you.
Which vial strengths can I enter for CJC-1295?
The calculator accepts the strengths this peptide is commonly supplied in, typically 5 mg and 10 mg lyophilized vials, sold as either a DAC or a no-DAC product. Enter the exact milligram figure printed on your vial; a 5 mg and a 10 mg vial reconstituted with the same water volume yield different concentrations.
I’m trying to decide between CJC-1295 and ipamorelin — does this page help?
This tool only handles the reconstitution math once you’ve chosen a compound; it doesn’t compare peptides. For a side-by-side look at how the two differ, see our comparison at /compare/cjc-1295-vs-ipamorelin, then return here to run the numbers for whichever vial you have.
