Tesamorelin dosage calculator

This tesamorelin calculator converts the Egrifta SV example into mL and syringe units. It uses the SV vial strength. Egrifta WR has its own mixing instructions.

Egrifta SV uses the sterile water supplied in its pack. It is used right after mixing. These presets are for SV, not WR. Changing an input changes the math, not the product instructions.

0.35 mL in the syringe · 1 calculated dose from this amount

35.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.35 milliliters. The nearest syringe line is 36 units.

This falls between two syringe lines. The nearest line on this U-100 syringe is 36 units. Open the syringe details below to see the difference.

2 mg ÷ 0.5 mL = 4.00 mg/mL
→ 40 mcg/unit · 1.4 mg = 0.350 mL = 35.0 units

Show the math and syringe details

Can this syringe show the result clearly?

This draw falls between syringe lines. The exact volume is 35.00 units, but a U-100 syringe has a line every 2 units. Using the nearest line gives 36 units — a 2.9% difference, or 40 mcg.

This setup is in the address bar — every input is part of the link.

How to use the calculator

  1. 1

    Enter the amount in the vial

    Use the total mg printed on your Tesamorelin vial.

  2. 2

    Enter the supplied sterile water

    Use the supplied sterile-water amount for SV. Changing the input does not change the product instructions.

  3. 3

    Enter the dose you want to convert

    Choose mg or mcg, then match the result to your syringe.

Tesamorelin is a prescription copy of the hormone that prompts growth hormone release, sold as Egrifta. It is approved for one thing: reducing excess belly fat in adults with HIV-related lipodystrophy. It is bought off-label for visceral fat and for general anti-aging.

Its label is unusually blunt about the second use. It says the drug is not approved for weight loss, and describes the effect on body weight as neutral.

Examples using 2 mg of Tesamorelin

Each row uses 2 mg and the liquid volume shown. Dividing the amount by that volume gives the calculated concentration. The rows are arithmetic examples, not alternative product preparations.

The amount, liquid volume and dose shown here are the calculator’s starting example for Tesamorelin. Replace them with your own values. Every result in the table is calculated from those inputs.

Tesamorelin calculations depend on the Egrifta formulation

Egrifta SV and Egrifta WR have different vial strengths, doses, mixing liquids and storage instructions. The presets on this page use the SV vial strength. They do not describe WR, and the labels say the two products cannot be swapped.

Open the mixing details3 notes

The SV vial is for a single dose

At the default SV amount, the calculator counts one full dose from the selected vial. The remainder is less than another full dose. This describes the SV inputs on this page, not every product containing tesamorelin.

The SV label says to use it right after mixing and discard any unused solution. Liquid left in the vial does not change that rule. It does not turn a single-dose vial into a stored supply.

The supplied mixing liquid is part of the instructions

SV uses the Sterile Water for Injection supplied in its pack. WR uses its supplied Bacteriostatic Water for Injection. A generic water field does not make those liquids interchangeable.

Changing the volume changes the strength of the mix and the draw. Some example inputs need more liquid than a U-100 barrel holds. That flags the amount entered. It does not mean to change the label’s mixing steps or split an injection.

WR needs its own concentration and storage information

The WR label states the strength of the finished mix and how long it can be used. Those facts belong to WR, not SV. Dividing vial mass by water volume does not replace the final strength stated on the label.

The ingredient name alone cannot select the right instructions. Vial strength, dose, liquid, final concentration and storage limits need to come from the same formulation. Combining values from the two labels can produce a plausible but wrong draw.

Egrifta SV and WR have different mixing instructions

Egrifta SV and Egrifta WR both contain tesamorelin, but use different doses, vial strengths, mixing liquids and storage rules. Their labels say they cannot be swapped. The ingredient name alone does not identify which instructions apply.

Read the supporting evidence3 supporting notes

SV uses its supplied sterile water

SV must be mixed with the Sterile Water for Injection supplied in its pack and used right away. A generic setting for bacteriostatic water does not replace those label instructions, even if the tool returns a plausible volume.

WR has its own preparation and storage limits

WR uses the supplied bacteriostatic water and has a defined period for using the mixed vial. That period belongs to WR. It cannot be borrowed for SV or for another tesamorelin preparation.

A label dose comes with more than arithmetic

The labels also say who can use the medicine, what tests are needed and when to stop. The tool converts the amount entered into a liquid volume. It cannot choose the product or check those health conditions.

Units to dose at 4.00 mg/mL

Mix 2 mg into 0.5 mL and one U-100 unit carries 40.0 mcg. The table shows how much peptide is in each numbered syringe line. These are conversion examples, not suggested doses.

How the math works

  1. Concentration — divide the amount entered by the liquid volume used in the calculation: mg ÷ mL = mg/mL. This tells you how many mg are in each mL.
  2. Volume — the dose divided by that concentration: dose ÷ (mg/mL) = mL.
  3. Units — on a U-100 syringe one unit is 0.01 mL, so mL × 100 = units. A U-40 unit is 0.025 mL, so the wrong barrel is a 2.5× error. That is why the calculator asks which one you have.
  4. Rounding gap — the exact draw against the nearest syringe line: |exact − nearest line| ÷ exact × 100 = % difference.

Questions readers ask

How to reconstitute 10 mg of tesamorelin?

10 mg is not a strength either approved form comes in. Egrifta SV holds 2 mg a vial and Egrifta WR holds 11.6 mg, and their own labels state the two are not substitutable.

The arithmetic for 10 mg is ordinary. 1 mL gives 10 mg/mL and 2 mL gives 5, so the labeled 1.4 mg daily quantity reads 14 or 28 units. Note that the WR label states 8 mg/mL after 1.3 mL of diluent, which plain division does not produce.

How do I reconstitute 5mg of tesamorelin?

Not a strength on this page either, which carries the 2 mg Egrifta SV vial alone. A 5 mg vial would read 10 mg/mL at 0.5 mL, 5 mg/mL at 1 mL, and 2.5 mg/mL at 2 mL.

The 1.4 mg daily quantity draws 14, 28 or 56 units across those. A 5 mg vial would also hold three of those doses where the 2 mg vial holds one. That difference is why the SV label treats its vial as a single dose and the rest as waste.

How much BAC water for 10mg tesamorelin calculator?

For the vial the label actually describes, the answer is 0.5 mL, far below the volumes most compounds here use. 2 mg in 0.5 mL is 4 mg/mL, and the 1.4 mg dose is 0.35 mL — the 35 units that volume implies.

Reach past it out of habit and the arithmetic bites. The same 2 mg vial in 2 mL puts one daily dose at 140 units, which will not fit a U-100 barrel. On a 10 mg vial the pressure runs the other way, since more powder tolerates more water.

Is 1 mg of tesamorelin enough?

Enough for what is the half nobody can answer, but the labeled quantities are on record and 1 mg is not among them. Egrifta SV sets 1.4 mg once daily, and Egrifta WR sets 1.28 mg.

Both labels cover one use: reducing excess abdominal fat in HIV-infected adults with lipodystrophy. Both also state the drug is not for weight loss management, and that its effect on body weight is neutral. No trial tested 1 mg, so no result exists at that quantity to compare.
