Tesamorelin Dosage Calculator

Tesamorelin's licensed dose is 2 mg daily, but research vials come in several sizes. Enter yours below to get the exact insulin-syringe draw.

This is a unit converter. It converts an amount you already have into volume and syringe units. It does not tell you what to take, and it is educational only — not medical advice. Confirm every amount with your clinician and your product label.

Example mixes to try the converter

Examples only — not recommended amounts. These fill in a vial size and diluent volume only — never an amount to inject. Enter the dose your clinician gave you yourself.

Vial size (mg)

Total compound in the vial.

BAC water added (mL)

Volume of bacteriostatic water you reconstitute with.

Target dose

Enter your target dose as a number.

Syringe type

U-100 = 100 units per mL (standard). U-40 = 40 units per mL.

Tesamorelin concentration reference (mg/mL)

What each vial size becomes at common bacteriostatic water volumes.

Vial	+ 1 mL	+ 2 mL	+ 3 mL	+ 5 mL
2 mg	2.00 mg/mL	1.00 mg/mL	0.67 mg/mL	0.40 mg/mL
5 mg	5.00 mg/mL	2.50 mg/mL	1.67 mg/mL	1.00 mg/mL
10 mg	10.00 mg/mL	5.00 mg/mL	3.33 mg/mL	2.00 mg/mL

Tesamorelin doses reported in research

The figures below are doses reported in published clinical trials or, where no human trials exist, ranges reported anecdotally. They are reference data only. DoseRoutine does not recommend doses — your prescriber decides yours.

Phase	Dose	Frequency	Notes
Licensed dose	2 mg	Once daily	Egrifta, for HIV-associated lipodystrophy.
Timing	—	Before bed, fasted	Aligns with the natural nocturnal GH pulse.
Site	—	Subcutaneous abdomen	Rotate sites; injection-site reactions are the most common complaint.
Assessment	—	At ~6 months	Visceral fat response is evaluated before continuing.

Reference ranges reported in the literature and in common practice — not a prescription, and not personalized advice.

What trips people up

10 mg + 2 mL = 5 mg/mL, so the standard 2 mg dose is 40 units on a U-100 syringe.
Tesamorelin is a GHRH analogue — it amplifies your own pulses rather than replacing GH, so effects build over months.
It can raise IGF-1 and worsen glucose control. Monitoring both is standard practice.
Contraindicated in pregnancy and in active malignancy.

How the math works

Concentration (mg/mL) = vial mg ÷ bacteriostatic water mL.
Volume per dose (mL) = dose mg ÷ concentration.
Syringe units = volume × 100 on a U-100 syringe, or × 40 on a U-40 syringe.
Doses per vial = vial mg ÷ dose mg. Water volume never changes this number.

Tesamorelin calculator FAQ

How many units is 2 mg of tesamorelin?

At 5 mg/mL (10 mg vial + 2 mL BAC water) it is 0.4 mL = 40 units on a U-100 syringe. At 2 mg/mL (10 mg + 5 mL) the same dose is 100 units — a full syringe.

How much BAC water for a 10 mg tesamorelin vial?

2 mL is the most common, giving 5 mg/mL and a clean 40-unit draw for the standard 2 mg daily dose. 1 mL halves the volume to 20 units if you prefer smaller injections.

Is tesamorelin dosed daily or weekly?

Daily. Unlike CJC-1295 with DAC, tesamorelin has a short half-life and the licensed protocol is 2 mg subcutaneously once every day, usually at night.

How long until tesamorelin works?

Visceral fat changes in the pivotal trials were measured at 26 weeks. This is a months-long compound, not a weeks-long one.
