HGH Reconstitution & Dosage Calculator
Calculate your HGH dose in syringe units. Convert prescribed IU doses to the units you draw after reconstituting with bacteriostatic water. Defaults to the standard 3 IU/mg potency - override only if your vial label says otherwise.

How the HGH maths works
HGH is measured in international units (IU), but reconstitution maths runs on concentration. The calculator converts your vial's IU to milligrams using the potency - 3 IU per milligram by international convention - then divides by the bacteriostatic water you added to get the concentration in IU per millilitre. Your dose in IU divided by that concentration gives the millilitres to draw, and multiplying by 100 reads the units on a U-100 insulin syringe.
Adding more bacteriostatic water makes a weaker solution, so each dose is a larger, easier-to-measure volume; less water makes a stronger solution and a smaller draw. Either is fine as long as you enter the actual volume you used.
Choosing a diluent
Bacteriostatic water - sterile water with 0.9% benzyl alcohol - is the usual choice for a multi-dose vial, because the preservative lets you draw from it over about 28 days in the fridge. Sterile water has no preservative, so a vial reconstituted with it is single-use and should not be kept. People who react to benzyl alcohol sometimes use sterile water or a 0.9% sodium chloride (saline) diluent instead. Whatever you use, follow your pharmacy label.
HGH calculator FAQ
How do I reconstitute HGH?
To reconstitute HGH, inject bacteriostatic water slowly down the inside wall of the vial - never directly onto the powder - and let it dissolve without shaking. Most HGH vials use 1 mL of bacteriostatic water, but always follow your pharmacy label. Once reconstituted, store it in the fridge and use within about 28 days.
How do I work out my HGH dosage in syringe units?
Enter your vial strength in IU, the volume of bacteriostatic water you added, and your prescribed dose in IU. The calculator converts the IU dose to the millilitres and syringe units you draw on a U-100 insulin syringe. Always use the dose your prescriber specified - this calculator does the arithmetic, not the prescribing.
What is the 3 IU/mg potency?
It is the international conversion between international units and milligrams for somatropin - 1 mg is about 3 IU. The calculator uses it by default; only change it if your vial label states a different potency.
How much bacteriostatic water should I add?
Whatever your pharmacy label specifies. If it does not, 1 mL is the most common choice for HGH. Enter the actual volume you used so the units are right.
Which syringe do the units assume?
A U-100 insulin syringe, where 1 mL is 100 units. Check the markings on your own syringe before drawing.
Can I use this calculator for other peptides?
Yes, if your peptide is marked in IU and you know its IU-to-mg potency. For IU-marked peptides that are not HGH, use the IU Calculator instead. For milligram-marked peptides, use the Dose Volume Calculator.
