Tesamorelin dosing chart in units
| Your dose | 10 mg vial + 2 mL | 20 mg vial + 2 mL |
|---|---|---|
| 1.4 mg | 28 units | 14 units |
Dose rows are the steps on the FDA label.
How many units for 1.4 mg
Everything here assumes a U-100 insulin syringe, the common kind where 100 units equal 1 mL, so every little mark on it measures 0.01 mL. You have to mix the powder in a vial with water before you can use it, and how much water you put in decides how strong that liquid ends up being.
| Vial | Water you add | Strength of the mix | Units needed |
|---|---|---|---|
| 10 mg | 1 mL | Each mL holds 10 mg | Draw 14 units |
| 10 mg | 2 mL | Each mL holds 5 mg | Draw 28 units |
| 20 mg | 1 mL | Each mL holds 20 mg | Draw 7 units |
| 20 mg | 2 mL | Each mL holds 10 mg | Draw 14 units |
Strength just means how many mg of tesamorelin are in each mL of the mixed liquid. When the mix is stronger, you need fewer units for the same dose.
How to use the chart
Look for the line that matches both your vial size and the amount of water you used. The final column shows how many units to draw for 1.4 mg. For example, if you added 2 mL of water to a 10 mg vial, you would draw up to the 28 unit mark.
Your vial size and the amount of water you added matter equally. The same 1.4 mg dose could be 7 units or 28 units depending on your mix, so it helps to write down how much water you used.
What the Egrifta SV label says
The Egrifta SV prescribing information on DailyMed lists a dose of 1.4 mg taken once daily, given under the skin. That is also the highest amount allowed. The label, for the brand's own 2 mg vial, gives this dose as 0.35 mL of the mixed liquid. Online sellers offer 10 mg and 20 mg sizes, and that is the reason the unit numbers here do not match the label's mL figure. Which dose applies to you is something your prescriber decides.
Approval status of tesamorelin
Tesamorelin has FDA approval for a single use in adults with HIV, sold under the brand names Egrifta SV and Egrifta WR. Vials sold for research purposes have no FDA approval, as the label listing shows.
Working out the numbers
You don't need to do any math. Just find your vial size and water amount in the chart. If your mix isn't listed, ask your prescriber or pharmacist to work out the units with you.
Questions people often ask
What is a chart like this for?
It turns the mg amount into a mark you can actually see on a syringe. That way you do not have to work out the strength of your mix again each time.
