To calculate tesamorelin dosage, divide your target dose (mg) by the vial concentration. Concentration = vial mg ÷ BAC water mL. For a 5 mg vial with 2 mL BAC water: concentration is 2.5 mg/mL. A 0.5 mg dose equals 0.2 mL (20 U-100 units) on a standard insulin syringe. On this page

How to Calculate Tesamorelin Dosage
Three steps convert any vial and BAC water combination into the exact volume to draw on a U-100 insulin syringe.
Step 1 — Calculate concentration (mg/mL)
Divide the total peptide in the vial (mg) by the volume of BAC water you added (mL). For example: a 5 mg Tesamorelin vial reconstituted with 2 mL BAC water gives 5 ÷ 2 = 2.5 mg/mL.
Step 2 — Calculate draw volume (mL)
Divide your target dose (mg) by the concentration (mg/mL). For a 0.5 mg dose at 2.5 mg/mL: 0.5 ÷ 2.5 = 0.2 mL. This is the exact volume to draw into the syringe.
Step 3 — Convert to U-100 syringe units
Multiply the draw volume (mL) by 100. For 0.2 mL: 0.2 × 100 = 20 U-100 units. Read this number on the unit markings of a standard insulin syringe.
Dosage Formula
Concentration formula
Concentration (mg/mL) = Vial mg ÷ BAC water mL
Draw volume formula
Draw volume (mL) = Dose (mg) ÷ Concentration (mg/mL)
U-100 syringe units
U-100 units = Draw volume (mL) × 100
These three formulas apply to any Tesamorelin vial, regardless of size. U-100 is the standard insulin-syringe scale: 100 units = 1 mL.

Example Tesamorelin Calculations
Step-by-step worked examples using common vial sizes. Results are for illustrating the math only.
5 mg vial + 2 mL BAC water, 0.5 mg dose
Vial: 5 mg | BAC water: 2 mL | Target dose: 0.5 mg Concentration: 5 ÷ 2 = 2.5 mg/mL Draw volume: 0.5 ÷ 2.5 = 0.2 mL U-100 units: 0.2 × 100 = 20 units
10 mg vial + 5 mL BAC water, 1 mg dose
Vial: 10 mg | BAC water: 5 mL | Target dose: 1 mg Concentration: 10 ÷ 5 = 2 mg/mL Draw volume: 1 ÷ 2 = 0.5 mL U-100 units: 0.5 × 100 = 50 units
Tesamorelin Reconstitution Guide
Tesamorelin is commonly supplied as a lyophilised powder in 5 mg or 10 mg vials. Reconstitution math depends on the total peptide in the vial and the amount of BAC water added.
Swab both vial stoppers with alcohol and allow them to dry. Inject BAC water slowly along the glass wall rather than directly onto the powder. Gently swirl until the solution is clear. Do not shake. Store reconstituted tesamorelin refrigerated at 2–8 °C and verify use windows from your source material.
Frequently Asked Questions How do I calculate tesamorelin draw volume?
Divide the target dose (mg) by the concentration (mg/mL). For a 5 mg vial with 2 mL BAC water, the concentration is 2.5 mg/mL. A 0.5 mg dose equals 0.2 mL, which is 20 U-100 units. What are U-100 syringe units?
U-100 is the standard scale for insulin syringes. 100 units = 1.0 mL. That means 10 units = 0.1 mL, 50 units = 0.5 mL. Multiply any draw volume in mL by 100 to get the U-100 units reading. Do I need to recalculate if I change the amount of BAC water?
Yes. Changing BAC water volume changes the concentration (mg/mL), which changes the draw volume for the same mg dose. Always recalculate using: concentration = vial mg ÷ BAC water mL, then draw volume = dose mg ÷ concentration. What is a common tesamorelin reconstitution example?
A common example is 5 mg plus 2 mL BAC water, which yields 2.5 mg/mL. At that concentration, every 0.1 mL equals 0.25 mg and every 0.2 mL equals 0.5 mg. Does this page recommend a tesamorelin dose?
No. This calculator only converts your vial strength, BAC water volume, and target amount into mL and U-100 syringe units. It does not provide personalized dosing advice.
