To find the units for Tesamorelin, you need two numbers: how many milligrams (mg) are in your vial, and how many milliliters (mL) of liquid you added to mix it. From those, the math gives you the concentration and the syringe units for any dose. Note that Tesamorelin is a prescription medicine (FDA-approved as Egrifta for HIV-associated lipodystrophy); outside that approved use it is compounded or investigational. This page is educational only — it is not medical advice, and it does not recommend a dose. Always follow your prescriber and pharmacist.
Tesamorelin is a peptide that is FDA-approved under the brand name Egrifta for treating HIV-associated lipodystrophy. In that approved use it is a prescription medicine. Outside of that approved indication, Tesamorelin is typically supplied as a compounded or research compound rather than an approved product. Because the legal and approval status depends on how it is supplied and used, you should treat this page as general educational information and rely on your physician and pharmacist for anything specific to you.
The FDA-approved Egrifta product comes packaged with its own supplied diluent, and the product instructions tell you exactly how to mix it. Compounded Tesamorelin vials are commonly reconstituted with bacteriostatic water. Whichever diluent is used, the choice of liquid does not change the units-to-draw math — the calculation only depends on the milligrams in the vial and the number of milliliters you add. The diluent question is about what liquid to use and is one to confirm with your pharmacist; the arithmetic below stays the same either way.
The two-step formula is:
(On a standard U-100 insulin syringe, 100 units = 1 mL. Remember that 1 mg = 1000 mcg.)
Example 1 — example only; your vial may differ, confirm with your pharmacist. Suppose a vial holds 5 mg and you add 2 mL of water. Concentration = 5 × 1000 ÷ 2 = 2500 mcg per mL. If someone were measuring a 1000 mcg amount purely as arithmetic: 1000 ÷ 2500 × 100 = 40 units. This is a neutral illustration of the math, not a recommended dose.
Example 2 — example only; your vial may differ, confirm with your pharmacist. Suppose a vial holds 10 mg and you add 2 mL of water. Concentration = 10 × 1000 ÷ 2 = 5000 mcg per mL. To measure a 1000 mcg amount as arithmetic: 1000 ÷ 5000 × 100 = 20 units. Notice how the same number on the label can mean a different number of units depending only on the water you added — which is why you should always run your own vial's numbers.
You may see various Tesamorelin amounts described online and in product literature. These are mentioned here strictly as educational context — they are not a recommendation, and what is right for you is a decision for your physician. Do not pick a number from a calculator or a forum. Use the prescriber's instructions and your pharmacist's guidance, and use this tool only to check the mixing arithmetic for the vial in front of you.
This is a mixing-math and concentration tool, not a dosing tool, and it cannot tell you whether a compound, an amount, or a product is appropriate or safe for you. A few honest reminders:
Pepathary is a free, offline, educational tracker. It does not sell, source, or recommend any product, compound, or dose.
There is no single answer — it depends on the concentration of your mixed vial. For example only: if a 5 mg vial is mixed with 2 mL of water (2500 mcg per mL), 1000 mcg would be 40 units; if a 10 mg vial is mixed with 2 mL (5000 mcg per mL), the same 1000 mcg would be 20 units. Run your own vial's mg and water through the formula, and confirm any amount with your physician — this is mixing math, not a dose recommendation.
That is a question for your pharmacist, and for the approved Egrifta product you should follow the supplied mixing instructions. The amount of water you add is your choice within those instructions — more water makes a more dilute mix (more units per dose), less water makes a more concentrated mix (fewer units). Once you know your water amount, this page shows how to turn it into units. It does not tell you how much water to use.
Yes, for one specific use: Tesamorelin is FDA-approved under the brand name Egrifta for HIV-associated lipodystrophy, where it is a prescription medicine. Outside that approved use, it is typically supplied as a compounded or research compound. Because the status depends on how it is supplied and used, confirm specifics with your physician and pharmacist.
No. The units-to-draw calculation depends only on the milligrams in the vial and the milliliters of liquid you add. Whether the liquid is the supplied diluent for the approved product or bacteriostatic water for a compounded vial, the math is identical. The diluent choice itself is a pharmacist question, not a math question.
No. This is a reconstitution (mixing-math) tool that converts your vial mg and water mL into a concentration and syringe units. It does not recommend, select, or endorse a dose, and the example numbers shown are neutral illustrations of arithmetic only. Always follow your physician's and pharmacist's instructions.
