Reconstitution calculator
Concentration, draw volume, U-100 syringe units, and doses per vial from vial size, water volume, and dose.
Review-gated tool: this calculator is excluded from search and AI citation. It is not dosing, reconstitution, injection, or treatment guidance and has no named clinician review.
CJC-1295 has no label, so unlike an approved injectable there are no official mixing constants: every number here is user-entered arithmetic, not product guidance. The calculator converts a vial strength and diluent volume into concentration, then converts any documented dose into injection volume and U-100 syringe units. It exists because the arithmetic is where dangerous mistakes happen, not because any dose is endorsed: no established human dose exists, and FDA has linked this compound to serious adverse-event reports.
Results
- Concentration

- Volume per dose
- 0.05 mL
- U-100 syringe units per dose
- 5 unitsFits the 1 mL barrel (100 unit scale).
- Full doses per vial
- 20 doses
This number came from the vial label, which no regulator reviewed.
Arithmetic only: concentration = vial mg / water mL; units = mL x 100. It does not check any dose against any reference.
Worked example
Worked example (arithmetic, not a recommendation): a vial labeled 2 mg mixed with 1 mL of water gives 2 mg/mL, so 0.1 mL contains 200 mcg. A documented dose of 100 mcg is 0.05 mL, which reads as 5 units on a U-100 syringe, and the vial holds floor(2000/100) = 20 such doses. For scale: the trials dosed by body weight (30 to 60 mcg/kg, weekly-scale), which for a 70 kg adult is 2.1 to 4.2 mg per dose: a different regime entirely from forum microdosing, and further evidence the two dosing cultures are not describing the same drug.
Step by step
- Enter the vial's stated peptide content in mg (whatever the label on your vial claims; this tool cannot verify it).
- Enter the volume of bacteriostatic or sterile water you add, in mL.
- Read the resulting concentration in mg/mL and mcg per 0.1 mL.
- Enter a dose in mcg to see its volume in mL and its mark on a U-100 insulin syringe.
- Read doses-per-vial as arithmetic floor(vial content / dose); it assumes the label is accurate, which nobody has verified.

Frequently asked questions
How do mg, mcg, mL, and syringe units relate?
Units measure volume, not peptide: a U-100 syringe marks 100 units per mL, so units = mL x 100. At 2 mg/mL, a 100 mcg dose is 0.05 mL, read as 5 units; dilute the same vial to 1 mg/mL and the same dose reads 10 units. Concentration decides the mark, so recompute after every mixing change.
Does this calculator care whether the vial is DAC or no-DAC?
The arithmetic is identical; the meaning is not. With DAC the compound lasts days (half-life 5.8 to 8.1 days), so doses stack week over week; without DAC it clears in minutes-scale time. Same syringe mark, completely different exposure. If the vial does not say which form it is, that is the finding.
Can this tool tell me what is actually in the vial?
No, and neither can the label. Gray-market peptides get no FDA review, reviews document frequent mislabeling, and the one published forensic analysis of seized CJC-1295 found a 29-residue peptide where the DAC form's registry sequence runs 30. The math assumes the label; the label is the weak link.
