Calculators / Dihexa
Dihexa reconstitution calculator
Enter your vial size, bacteriostatic water, and target dose — get the concentration, the exact U-100 syringe draw, and how many doses the vial holds. No account, no vendor ties, numbers never leave your browser.
⚠ A 12 mg dose is more than the 10 mg in the whole vial — check whether the dose was meant to be micrograms.
⚠ A 240-unit draw does not fit a U-100 syringe (max 100 units) — use more bacteriostatic water, or split the dose across draws.
How the math works
Three formulas, checked twice — the same engine that powers the Zyra Track app:
- concentration (mg/mL) = peptide in vial (mg) ÷ BAC water (mL)
- draw volume (mL) = dose ÷ concentration
- U-100 units = draw volume (mL) × 100
Worked example: 10 mg Dihexa + 2 mL water = 5 mg/mL. A 12 mg dose is then 12 mg ÷ 5 mg/mL = 2.4 mL = 240 units on a U-100 insulin syringe.

Frequently asked
How much BAC water should I add to a 10 mg Dihexa vial?
There is no single correct amount — the water volume sets the concentration, not the dose. Adding 2 mL to 10 mg gives 5 mg/mL, which puts a 12 mg draw at 240 units on a U-100 insulin syringe. More water = larger, easier-to-measure draws; less water = smaller draws.
How many units is 12 mg of Dihexa?
It depends entirely on your concentration. At 5 mg/mL (10 mg + 2 mL), 12 mg is 240 units on a U-100 syringe. Use the calculator above with your own vial and water volumes.
What is the half-life of Dihexa?
Dihexa's reported half-life is ≈ 8.8 days (rat). See our cited half-life reference for the decay curve and clearance math.
