If you’re searching for how much BAC water for 2mg Tesamorelin, the most commonly used dilution method is to add 1mL of bacteriostatic water (BAC water) to a 2mg Tesamorelin vial. This creates a concentration that allows straightforward insulin syringe calculations.
This guide explains how to mix 2mg Tesamorelin, provides a 2mg Tesamorelin reconstitution chart, and includes a Tesamorelin insulin syringe calculator to simplify common conversions.

The most common way to reconstitute a 2mg vial of Tesamorelin is with 1mL of bacteriostatic water.
This creates a concentration of 2mg/mL.
Using a 100-unit insulin syringe:
5 units = 100mcg 10 units = 200mcg 25 units = 500mcg 50 units = 1,000mcg
Many people prefer this dilution because it provides simple syringe calculations and practical injection volumes.
What Is Tesamorelin?
Tesamorelin is a synthetic growth hormone-releasing factor (GHRF) analogue. It is approved for reducing excess abdominal fat in adults with HIV-associated lipodystrophy (source)
It is supplied as a lyophilised powder, meaning it must be mixed with an appropriate diluent before use.

How to Mix 2mg Tesamorelin
Step 1: Gather Supplies
You will need:
2mg Tesamorelin vial Bacteriostatic water Alcohol swabs Sterile mixing syringe Insulin syringe
Step 2: Clean the Vials
Clean the rubber stoppers on both vials using alcohol swabs.
Allow them to air dry completely.
Step 3: Draw the BAC Water
Using a sterile syringe, slowly withdraw your chosen amount of bacteriostatic water.
For this guide:
1mL BAC water
Step 4: Inject Slowly
Insert the needle into the Tesamorelin vial.
Allow the BAC water to run slowly down the inside wall of the vial.
Avoid spraying directly onto the powder.
Step 5: Allow the Powder to Dissolve
Do not shake the vial.
Instead:
Gently swirl the solution Roll the vial between your fingertips if needed
The powder typically dissolves within several minutes.

Why Use Bacteriostatic Water?
Bacteriostatic water contains 0.9% benzyl alcohol, which helps inhibit bacterial growth after the vial has been punctured.
Compared with sterile water, BAC water may provide extended protection against contamination.
Always follow the instructions supplied with your medication.
How Long Does Reconstituted Tesamorelin Last?
Storage recommendations vary depending on the manufacturer.
General guidance may include:
Refrigeration between 2°C and 8°C Protection from direct sunlight Avoiding repeated temperature fluctuations
Always refer to the package insert or consult your pharmacist regarding storage requirements.
Is 0.5mL or 1mL Better for 2mg Tesamorelin?
0.5mL BAC Water
Advantages:
Smaller injection volumes More concentrated solution
Disadvantages:
Less room for measurement errors More difficult calculations
1mL BAC Water
Advantages:
Easier insulin syringe conversions Greater dosing precision More practical for most users
Disadvantages:
Slightly larger injection volumes
For these reasons, 1mL is often considered the simplest dilution method for a 2mg Tesamorelin vial.
Common Tesamorelin Mixing Mistakes
Avoid these common preparation errors:
Shaking the vial vigorously Injecting BAC water directly onto the powder Using incorrect insulin syringe conversions Using expired bacteriostatic water Failing to follow storage recommendations Reusing syringes or needles
Careful preparation can help minimise dosing errors.
