Bacteriostatic water, 10ml →Understanding units
The calculator tells you how many units to draw. Here is exactly what a unit is, and why it means the same thing on every insulin syringe.
On a U-100 insulin syringe one unit is a hundredth of a millilitre. So 10 units is 0.1 mL, and 100 units is 1 mL. Units simply make very small volumes easier to read off the barrel.
It does not matter which insulin syringe you pick up. Drawing to 20 units pulls the same 0.2 mL on a 0.3 mL, a 0.5 mL or a 1 mL syringe. The tick marks never change size.
What changes between syringes is how many of those marks fit on the barrel. A bigger syringe is not a bigger unit, it is just more room.
Example: a 20-unit draw is 0.2 mL on all three syringes above. The only difference is how much empty barrel is left behind it.

How the tesamorelin calculator works
Tesamorelin is a 44 amino acid analogue of growth hormone releasing hormone, and for research it is supplied as a lyophilized powder. This tesamorelin calculator takes the vial strength and the volume of bacteriostatic water, then returns the concentration, the volume per amount and the syringe reading. It opens on a 10mg vial with 2mL of water. The amount field is empty on purpose, because the amount is set by the protocol a researcher is working to.
Tesamorelin reconstitution: matching the vial to its in-use window
A 10mg vial holds a lot of draws, and a mixed vial does not last forever. That makes tesamorelin a good case for planning before you add water. Bacteriostatic water is generally treated as good for 28 days after the first puncture, so the sums that matter are:
- Doses in vial: the vial mass divided by the amount per draw
- Draws you plan to take inside the in-use window
- Whether the first number is bigger than the second
If a vial holds far more draws than the window allows, the surplus is waste, and a smaller vial or a shorter run is the better fit. Adding more water does not extend the window. It only changes how the same mass reads on the syringe.
Tesamorelin dosage calculator: milligrams to units
Concentration is vial mass over water volume. A 10mg vial in 2mL is 5mg/mL, in 1mL it is 10mg/mL, and in 4mL it is 2.5mg/mL. Divide the amount by that concentration to get mL, then multiply by 100 for units on a U-100 syringe. At 5mg/mL, 1mg is 0.2mL, which is 20 units. Use the mcg toggle if your figures are in micrograms.
Confirm the vial and read around the compound
Every figure starts from the strength printed on the vial, so confirm it against the certificate of analysis for your batch. Healio publishes each one on the research page, and how to read a certificate of analysis explains which figures actually prove something. Once the vial is mixed, write the water volume, the concentration and the date on the label. Our guide to reconstituting peptides covers the handling, and how long bacteriostatic water lasts covers the in-use window.
Tesamorelin for sale from Healio is stocked as a 10mg vial. Tesamorelin peptides covers the approved-use background, and sermorelin vs tesamorelin compares it with a related compound. For another calculator see the GHK-Cu calculator, or use the all-peptide calculator.
Tesamorelin calculator FAQ
How much bacteriostatic water goes in a tesamorelin vial?
There is no fixed volume. For a 10mg vial, 1mL gives 10mg/mL, 2mL gives 5mg/mL and 4mL gives 2.5mg/mL. The volume sets the concentration, which sets where an amount sits on the syringe scale.
How many doses are in a tesamorelin vial?
Divide the vial mass by the amount per draw. For a 10mg vial and a 1mg amount, that is ten draws on paper. The calculator shows it as doses in vial once you enter an amount.
Does more water make a tesamorelin vial last longer?
No. The in-use window starts at the first puncture and does not depend on the volume. More water only changes the concentration and how the amount reads on the syringe.
How do I convert tesamorelin mg to units?
Divide the amount by the concentration to get mL, then multiply by 100. At 5mg/mL, 1mg is 0.2mL, which is 20 units on a U-100 insulin syringe.
Does the tesamorelin calculator recommend an amount?
No. It converts the figures you enter and makes no recommendation. Healio supplies research compounds for laboratory use, so quantities belong to the protocol a researcher is working to.
How long is a reconstituted vial good for?
Reconstituted peptides are normally kept refrigerated, and bacteriostatic water is generally treated as good for 28 days after the first puncture. See how long bacteriostatic water lasts for the rule.
