How do I calculate a tesamorelin dose in syringe units?

Divide the vial's mg by the bacteriostatic water (or diluent) in mL for the concentration, divide your dose in mg by that concentration for the volume in mL, then multiply by 100 for U-100 syringe units. Example: a 2 mg vial mixed with 0.5 mL is 4 mg/mL; a 1.4 mg amount is 0.35 mL, which is 35 units.

What is the FDA-approved tesamorelin dose?

For its one approved indication — reducing excess visceral fat in HIV-associated lipodystrophy — the EGRIFTA SV label specifies 1.4 mg by subcutaneous injection once daily, reconstituted from a 2 mg vial with 0.5 mL of diluent (4 mg/mL), drawing 0.35 mL, which is 35 units on a U-100 syringe. That is a real, labelled figure for a specific medical condition — it is not a dosing recommendation for athletic or off-label use, which the label does not address.

Does the FDA-approved tesamorelin product require reconstitution?

Yes. EGRIFTA SV is supplied as a lyophilized powder in single-use 2 mg vials that must be reconstituted with the supplied diluent immediately before each injection and any unused solution discarded — it is not a ready-to-inject pen. A vial sold as tesamorelin for research or athletic use is not this approved product, and its identity and purity have not been verified by anyone.

Is tesamorelin approved for athletes, muscle gain, or weight loss?

No. Tesamorelin's only FDA approval is for reducing visceral fat in adults with HIV-associated lipodystrophy, and its label explicitly states it is not indicated for weight-loss management. There are no trials establishing a dose, benefit, or safety profile in healthy athletes, and off-label athletic use is prohibited in tested sport. See our full evidence review for the trial record behind the approval and where the athletic marketing runs out of support.

How many units is a given tesamorelin dose?

It depends entirely on the concentration you mixed. The same 1 mg amount is 25 units at 4 mg/mL, 20 units at 5 mg/mL, or 33.3 units at 3 mg/mL. Units measure a volume, not a mass, so an answer without a stated concentration is not a real answer.

Does this calculator recommend a tesamorelin dose for off-label use?

No. It converts a number you already have — a dose figure and a vial you mixed — into syringe units. Every field starts blank, the vial-strength chips fill a container size rather than an amount, and the one dose actually printed on this page is the FDA label's approved figure for a specific medical condition, not a suggestion for anyone reading it. Any decision to use tesamorelin belongs with a licensed clinician.

Tesamorelin Dosage Calculator

Tesamorelin is unusual on this site because it has a genuine FDA approval — as EGRIFTA SV, for a single narrow indication — and the approved product is itself a powder the patient reconstitutes before every dose. That makes the unit arithmetic below directly checkable against a real label, which is not true for most of the compounds this site covers.

Enter the vial size, the diluent you added, and the dose you are working out to see the volume and U-100 syringe units. It converts what you type and never proposes an amount — including for off-label athletic use, which the approval does not cover.

The math, before you use the tool

Concentration: mg/mL = vial (mg) ÷ diluent (mL)
Volume to draw: mL = dose (mg) ÷ concentration (mg/mL)
Syringe units: units = volume (mL) × 100 [U-100: 100 marks = 1 mL]
Draws per vial: draws = vial (mg) ÷ dose (mg)

The one real reference point: the FDA-approved EGRIFTA SV label reconstitutes a 2 mg vial with 0.5 mL of diluent (4 mg/mL) and draws 0.35 mL — 35 units — for its approved 1.4 mg daily dose in HIV-associated lipodystrophy. That figure is for a specific medical condition, not a general dosing guide.

Read this before you use the calculator

This tool performs unit arithmetic on numbers you enter, and nothing else. It is not medical advice, it does not recommend a dose, and it is not a suggestion that you use any compound. Most of the peptides these calculators get used with are not FDA-approved for the purposes they are marketed for, are sold through a grey market where purity and labelling are not guaranteed, and many are prohibited in tested sport — check yours with the WADA prohibited-status checker. Any decision to use a compound, and any amount, must come from a licensed clinician who knows your history. Tesamorelin's only FDA approval (as EGRIFTA SV) is for reducing visceral fat in adults with HIV-associated lipodystrophy; the label states it is not for weight-loss management, there is no approved athletic or performance indication, and material sold for research or off-label use is not the verified approved product.

Tesamorelin vial strengths commonly sold

These fill the vial-size field only. A vial strength is what the container holds — it is not a dose, and listing it is not a recommendation to use Tesamorelin.

Enter the vial size, the water you added, and the amount you are working out. Every field starts blank on purpose — this tool converts your numbers, it does not supply them.

This is arithmetic, not advice. Every figure above is derived only from the numbers you typed. Nothing here is a recommended dose, a claim that any compound is approved, safe, or effective, or a suggestion that you should use one. Confirm the vial label, the water volume, and the amount with a licensed clinician before you draw anything.

The FDA-approved EGRIFTA SV figure, per the label

1Concentration: 2 mg vial ÷ 0.5 mL diluent = 4 mg/mL
2Volume: 1.4 mg ÷ 4 mg/mL = 0.35 mL
3Units: 0.35 mL × 100 = 35 units

35 units — the labelled dose for HIV-associated lipodystrophy, not a general recommendation

A 5 mg vial mixed with 1 mL, working out 1 mg

1Concentration: 5 mg ÷ 1 mL = 5 mg/mL
2Volume: 1 mg ÷ 5 mg/mL = 0.2 mL
3Units: 0.2 mL × 100 = 20 units
4Draws per vial: 5 mg ÷ 1 mg = 5

20 units · 5 draws from the vial

The same 1 mg amount, at a 10 mg vial mixed with 2 mL

1Concentration: 10 mg ÷ 2 mL = 5 mg/mL — identical strength to the 5 mg/1 mL mix
2Volume and units are unchanged: 0.2 mL, 20 units
3Draws per vial: 10 mg ÷ 1 mg = 10 — double the draws, same reading

The part a calculator cannot answer

A number on a syringe is the easy half. Whether a compound does anything in humans, whether it is legal to buy, and whether it will end a season are the questions worth your time:
