Tesamorelin Dosage Calculator: Reconstitution and Units
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.

| Vial (mg) | BAC water (mL) | Concentration | Dose (mg) | Draw (mL) | U-100 units |
|---|---|---|---|---|---|
| 5 mg | 2 mL | 2.5 mg/mL | 0.25 mg | 0.1 mL | 10 units |
| 5 mg | 2 mL | 2.5 mg/mL | 0.5 mg | 0.2 mL | 20 units |
| 5 mg | 2 mL | 2.5 mg/mL | 1 mg | 0.4 mL | 40 units |
| 10 mg | 5 mL | 2 mg/mL | 1 mg | 0.5 mL | 50 units |
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 mLDraw volume formula
Draw volume (mL) = Dose (mg) ÷ Concentration (mg/mL)U-100 syringe units
U-100 units = Draw volume (mL) × 100These 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.
