If you’ve purchased a 10mg vial of Tesamorelin, one of the most common questions is:
“How much BAC water should I add?”
The simple answer is that there is no universally correct amount of BAC water for 10mg tesamorelin. The amount of bacteriostatic water (BAC water) used simply changes the final concentration of the solution, making it easier to measure the desired amount accurately.
Most individuals use 1mL, 2mL, or 5mL of BAC water, with 2mL being one of the most popular options because it provides straightforward insulin syringe calculations.
Quick Answer
For a 10mg Tesamorelin vial, the following BAC water amounts are commonly used:
BAC Water Added Final Concentration 1mL 10mg/mL 2mL 5mg/mL 3mL 3.33mg/mL 4mL 2.5mg/mL 5mL 2mg/mL
Most Common Choice
2mL of BAC water is frequently chosen because it offers:
Easier insulin syringe calculations Moderate injection volumes Improved measurement accuracy
What Is Tesamorelin?
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to release growth hormone.
This subsequently increases levels of insulin-like growth factor-1 (IGF-1), which plays a role in metabolism, body composition, and tissue growth.
Tesamorelin has been studied and prescribed in specific medical settings, particularly relating to HIV-associated lipodystrophy.
Tesamorelin and Egrifta®
Many people searching for tesamorelin are also interested in Egrifta®.
Is Egrifta the Same as Tesamorelin?
Yes.
Tesamorelin is the active ingredient in Egrifta®.
Egrifta is an FDA-approved medication used to reduce excess abdominal fat in adults with HIV-associated lipodystrophy.
The amount of BAC water used for reconstitution does not change the amount of tesamorelin present within the vial. It only changes the concentration of the final solution.
Is Tesamorelin FDA Approved?
Yes.
Tesamorelin is approved by the FDA under the brand name Egrifta® for reducing excess abdominal fat in adults with HIV-associated lipodystrophy.
Tesamorelin should only be used:
Under the supervision of a qualified healthcare professional For approved medical indications According to the prescribing information provided
What Is BAC Water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which acts as a preservative to help inhibit bacterial growth once a vial has been punctured.
BAC water is commonly used when reconstituting products intended for multiple uses.
The preservative allows repeated withdrawals when appropriate sterile techniques are followed.
Tesamorelin BAC Water Calculator
The concentration of a reconstituted solution can be calculated using the following formula:
Concentration = Total tesamorelin amount ÷ BAC water volume
Examples
Tesamorelin Amount BAC Water Added Final Concentration 10mg 1mL 10mg/mL 10mg 2mL 5mg/mL 10mg 5mL 2mg/mL
How to Reconstitute 10mg Tesamorelin
Step 1: Gather Your Supplies
You will need:
One 10mg tesamorelin vial BAC water Alcohol swabs Sterile mixing syringe Insulin syringes for measurement
Step 2: Clean the Rubber Stoppers
Use alcohol swabs to disinfect:
The tesamorelin vial stopper The BAC water vial stopper
Allow both surfaces to dry completely.
Step 3: Draw Up the BAC Water
Withdraw your preferred amount of BAC water.
Common choices include:
1mL BAC Water
Best for:
Smaller injection volumes Higher concentrations
2mL BAC Water
Best for:
Easier calculations Moderate concentrations
5mL BAC Water
Best for:
Larger syringe measurements Greater dosing precision
Step 4: Inject Slowly
Inject the BAC water slowly down the inside wall of the vial.
Avoid directing the stream directly onto the powder.
Step 5: Allow the Powder to Dissolve
Do not shake the vial aggressively.
Instead:
Gently swirl the solution Roll the vial between your fingertips Allow the contents to dissolve naturally
The final solution should appear clear.
10mg Tesamorelin Mixing Chart
If You Add 2mL of BAC Water
Desired Amount Volume to Draw Insulin Syringe Units 0.5mg 0.10mL 10 Units 1mg 0.20mL 20 Units 2mg 0.40mL 40 Units 2.5mg 0.50mL 50 Units
This is one of the most popular tesamorelin dilutions because it provides straightforward syringe calculations.
If You Add 5mL of BAC Water
Desired Amount Volume to Draw Insulin Syringe Units 0.5mg 0.25mL 25 Units 1mg 0.50mL 50 Units 2mg 1mL 100 Units 2.5mg 1.25mL 125 Units
Which BAC Water Amount Is Best?
BAC Water Best For Main Advantage 1mL Smaller injection volumes Higher concentration 2mL Most individuals Easier calculations 5mL Greater precision Larger measurements
There is no universally superior option.
The ideal dilution depends on:
Ease of measurement Desired concentration Personal preference Manufacturer recommendations
How Should Reconstituted Tesamorelin Be Stored?
Most manufacturers recommend storing reconstituted solutions:
In the refrigerator Between 2°C and 8°C Protected from direct sunlight
Always follow the storage guidance provided with your specific product.
Common Tesamorelin Mixing Mistakes
Using Non-Sterile Water
Only use:
BAC water, or Sterile water if specifically recommended by the manufacturer.
Shaking the Vial
Excessive agitation may damage delicate peptide structures.
Always mix gently.
Incorrect Calculations
Always verify:
The amount within the vial The volume of BAC water added The syringe measurements being used
Small calculation errors can significantly alter the final concentration.
Frequently Asked Questions
How much BAC water should I use for 10mg tesamorelin?
Many people choose 2mL of BAC water, although amounts ranging from 1mL to 5mL are commonly used.
What is the easiest dilution for 10mg tesamorelin?
Most individuals find that 2mL provides the simplest insulin syringe calculations.
How many insulin syringe units is 2mg of tesamorelin?
If 2mL of BAC water has been added to a 10mg vial, 2mg equals 40 insulin syringe units.
Does adding more BAC water change the amount of tesamorelin?
No. Additional BAC water changes the concentration of the solution, but not the total amount of tesamorelin within the vial.
Can tesamorelin be mixed with sterile water?
Some manufacturers permit sterile water, although BAC water is often preferred because it contains a preservative.
Does tesamorelin need refrigeration after mixing?
Most manufacturers recommend refrigeration after reconstitution.
Is Egrifta the same as tesamorelin?
Yes. Egrifta contains tesamorelin as its active ingredient.
How long does mixed tesamorelin last?
Storage recommendations vary depending on the product and manufacturer. Always follow the instructions supplied with your specific medication.
