How much water do I add to a 10 mg Epitalon vial?

The water amount is your choice, it only changes how strong each mL is. With 2 mL you get 5 mg per mL; with more water each unit holds less, which makes small doses easier to measure.

How many units is 1 mg of Epitalon?

It depends on the strength of your mix. At 5 mg/mL, 1 mg is 20 units. Enter your own vial and water in the calculator to get your number.

Epitalon dosage calculator

To see how many units to draw, enter your Epitalon vial size, water amount and dose for a U-100 insulin syringe.

Only for reference. Your dose comes from your prescriber or the product label; this site only converts it into units.

Available vial sizes: 10 mg, 50 mg
status of approval: It is not FDA-approved.
sample mix: 10 mg with 2 mL: 5 mg per mL

Understanding Epitalon math

Divide the amount in the vial by the water to find the strength. Each mL in a 10 mg vial mixed with 2 mL of water contains 5 mg. First divide your dose by that strength for mL, then multiply by 100 to get units on a U-100 syringe.

From that vial, 100 mcg equals 0.02 mL, or 2 units.

It isn't FDA-approved for any use in people; it's sold as a research chemical. Because no FDA label exists, no official dose is set. All we do is convert the dose you already have.
