CJC-1295 DAC reconstitution calculator.
CJC-1295 DAC carries a drug affinity complex that stretches its half-life from minutes to days, so it is dosed far less often than the no-DAC form. Same vial sizes, very different arithmetic, and the two get confused constantly.

Each unit on a 100u · 1.0 mL syringe ≈ 10 mcg of this solution.

More water → lower concentration → more units for the same amount.
What changes the math for CJC-1295 DAC.
- Vials are 2 mg or 5 mg. 2 mg in 2 mL is 1,000 mcg/mL, so 1 mg is 100 units, a full U-100 syringe.
- Because administration is infrequent, doses per vial is a small number and the vial's reconstituted stability window matters more than for daily compounds.
- Amounts quoted for DAC are typically an order of magnitude above no-DAC figures. Reading a no-DAC table against a DAC vial is the error to avoid.

CJC-1295 DAC: research formats
Choose the format you are researching to see route-specific notes.
The DAC version bonds to albumin and lasts 6–8 days, allowing much less frequent injections than no-DAC.
CJC-1295 DAC is typically sold as a 2 mg vial. Its albumin-binding Drug Affinity Complex (DAC) extends the half-life to approximately 6–8 days, so injections are spaced much further apart than no-DAC. Reconstituting 2 mg in 2.0 mL BAC water gives 1,000 mcg/mL.
Because the compound sustains GH elevation for days, the typical injection schedule in research contexts is once weekly or twice weekly, very different from the daily or multi-daily no-DAC pattern.
FAQ.
What is the difference between CJC-1295 with and without DAC?
The drug affinity complex binds the peptide to serum albumin, extending the half-life from roughly 30 minutes to several days. That changes frequency and the amounts discussed, though the reconstitution math is the same arithmetic.
How many units is 1 mg of CJC-1295 DAC?
On 2 mg in 2 mL (1,000 mcg/mL), 1 mg is 1,000 mcg, which is 100 units, the entire barrel of a U-100 syringe. Less water gives a smaller draw for the same amount.
Can I use a no-DAC concentration table?
Only if the vial size and water volume match exactly. The table describes a concentration, not a compound, so it transfers when the numbers do and misleads when they do not.
