Tesamorelin Dosage Calculator
This tesamorelin dosage calculator converts a dose in milligrams into the units to draw. Tesamorelin doses are in milligrams, not micrograms, which sounds simpler and mostly is. The trap is the vials: the prescription version comes in 2 mg vials, while research vials run 5, 10 and 20 mg, so the same dose is a very different draw depending on which label you are reading. Enter the vial, the water and your dose, and get the exact units.
Units measure volume, not dose. The same units on a different mix are a different dose.
The link holds only the numbers you typed. No account, no tracking, nothing else.

Tesamorelin dosage calculator table: dose to units for the common mixes
Three doses, five mixes. Because tesamorelin doses are whole milligrams, the draws are big and easy to read compared with the microgram compounds. The mix still decides the number, by a factor of four between the weakest and strongest rows here.
| Vial | Water | Concentration | 0.5 mg draw | 1 mg draw | 2 mg draw |
|---|---|---|---|---|---|
| 5 mg | 1 mL | 5 mg/mL | 10 units | 20 units | 40 units |
| 5 mg | 2 mL | 2.5 mg/mL | 20 units | 40 units | 80 units |
| 10 mg | 1 mL | 10 mg/mL | 5 units | 10 units | 20 units |
| 10 mg | 2 mL | 5 mg/mL | 10 units | 20 units | 40 units |
| 20 mg | 2 mL | 10 mg/mL | 5 units | 10 units | 20 units |
Look at the 1 mg column. It runs from 10 units to 40 depending on nothing but the vial and the water. A unit number quoted without a mix is meaningless for tesamorelin exactly as it is for every other compound, it is just a bigger, easier-to-read meaninglessness.
Two kinds of tesamorelin vial
Tesamorelin is unusual in this catalogue: it exists as an approved prescription medicine and as research powder at the same time. Egrifta SV, the approved brand, comes in 2 mg vials and is prescribed for one specific condition. Research suppliers sell the same compound name as loose powder in 5, 10 and 20 mg vials. Only one of those two is an approved medicine, and the methodology page records which is which.
For the arithmetic, the label is all that matters. A 2 mg vial and a 20 mg vial are both just a number of milligrams waiting for water, and the calculator above takes either, including amounts that are not in its preset list. Read the amount off the vial in front of you rather than assuming the size, because with this compound the sizes differ by a factor of ten between the two kinds.
Common questions
How many units is 1 mg of tesamorelin?
It depends on the mix. In a 10 mg vial with 2 mL of water (5 mg per mL), 1 mg is 20 units. The same vial with 1 mL of water is twice as strong, so 1 mg is 10 units. In a 5 mg vial with 2 mL (2.5 mg per mL), 1 mg is 40 units. The table above covers the common mixes.
How much BAC water do I add to a 10 mg tesamorelin vial?
Your choice, and the water sets how big the draw is. With 1 mL, a 1 mg dose is a 10 unit draw. With 2 mL it is 20 units, and with 3 mL it is 30 units. The dose is 1 mg every time. Pick the mix that puts your dose on a mark you can read easily, or work backwards from the draw you want with the reconstitution calculator.
Is tesamorelin measured in mg or mcg?
Milligrams, on the vial and in the dose. That makes it the opposite of a compound like BPC-157, where the vial is labelled in mg and the doses are in mcg. The trap still exists, just in the other direction: enter 1 into a field set to mcg and the answer comes out a thousand times too small. This calculator starts in mg for tesamorelin, and shows the dose back in both units so you can check it.
How many doses are in a 10 mg vial?
At 1 mg a dose, 10 doses. At 2 mg a dose, 5 doses. It is just the vial amount divided by the dose, and the water has nothing to do with the count. The calculator shows the count for your own numbers as you type.
What is the difference between Egrifta vials and research vials?
Egrifta SV is the approved prescription brand of tesamorelin, supplied in 2 mg vials for one specific condition. Research vials are loose powder in 5, 10 and 20 mg sizes, and they are not approved medicines. The compound name is the same, so the arithmetic is the same: enter the amount printed on your vial. The methodology page records the regulatory position properly.
Arithmetic only
This calculator does maths on the numbers you enter. It works out concentration, draw volume and syringe units from the vial amount and water volume you give it. Nothing more.
It does not recommend amounts, schedules or products, and it does not know what is in your vial. It uses the amount printed on the label. If the label and the actual contents differ, the result differs too. For medical questions, talk to a clinician.
