Tesamorelin is a daily injection people use specifically to reduce stubborn deep belly fat (visceral adipose tissue). It's an analog of growth hormone-releasing hormone (GHRH) that prompts the pituitary to release more of the body's own GH. In FDA trials for HIV-related lipodystrophy, daily 2 mg injections reduced visceral fat by about 15–18% over 26 weeks. This page covers reconstitution math and daily dose logging.
How the four Tesamorelin calculators connect
This tool turns the three numbers on your Tesamorelin vial into the only number that matters at injection time: how many units to draw on a U-100 insulin syringe. The math is one formula — concentration in mg per mL equals the milligrams of peptide in the vial divided by the milliliters of bacteriostatic water you add — and every other answer falls out of that.
In the worked example below, a 5 mg vial of Tesamorelin reconstituted with 2 mL of BAC water produces a concentration of 2.5 mg/mL. To draw the example dose of 1 mg from that vial you pull 0.40 mL — about 40 units on a standard insulin syringe. Change any input and the rest updates instantly so you can pre-plan a vial before you ever touch a needle.
Vial size, diluent volume, and dose are the three inputs that genuinely change the answer. Doses-per-vial is a derived output — it's the vial mg divided by the dose mg, rounded down. The most common edge case is a tiny dose: at very high concentration, a 0.1 mL draw is only a few units on the syringe, which is hard to read accurately. If your unit count drops below five, consider reconstituting the next vial with more BAC water so each dose covers a larger volume.
What the Tesamorelin calculators cover
This hub gathers the four Tesamorelin calculators in one place — reconstitution, dose, mg ↔ units, and vial duration — pre-filled with a 5 mg / 2 mL example so the math is concrete the moment the page loads. Tesamorelin sits in the GH Secretagogue category, and the numbers each tool surfaces are tuned to how people actually log this peptide: a daily shot at the 1 mg example dose. A full-length GHRH analog with a protective group for a longer half-life and higher dose volume.
At the example concentration of 2.5 mg/mL, a 1 mg Tesamorelin dose draws roughly 40 units on a U-100 insulin syringe — the Dose calculator on the hub shows that working in real time, and the mg ↔ units converter flips it back the other way for people who think in milligrams. The Reconstitution calculator answers the day-one question (how much bacteriostatic water to add and what concentration that gives), and the Vial Duration calculator answers the planning question (how many weeks one vial covers).
For this 5 mg Tesamorelin vial, the example numbers imply about 5 doses per vial and roughly 0.7 weeks of coverage at 7 doses per week — that's the math the Vial Duration tool exposes, and it's the number most people use to decide when to reorder. Every calculator on the hub uses these same five inputs (vial mg, diluent mL, dose, doses-per-week, syringe type), so changing your real numbers in one tool gives consistent answers across the others.
How people log Tesamorelin
Protocols documented in published research on Tesamorelin typically involve a daily administration cadence, scheduled for seven days per week. The studied dose is substantial, frequently specified at 1 mg or 2 mg per day, which requires a much larger injection volume compared to GHRH fragments dosed in micrograms. For a 1 mg dose, drawing from a moderately concentrated vial requires careful measurement, often with a standard 1 mL U-100 insulin syringe to ensure accuracy for volumes that can be 40 units or more.
In a departure from the common evening schedule for many GH secretagogues, clinical trials for Tesamorelin predominantly utilized a morning-dosing schedule. The rationale is linked directly to its extended half-life; since the peptide provides a sustained GHRH signal, it is not necessary to time its administration to coincide with the primary natural growth hormone pulse during sleep. This morning administration pattern is a well-documented characteristic of the protocols established during its clinical development for its approved indication.
The structural stability of tesamorelin directly informs the administration schedules observed in research literature. Its resistance to DPP-IV degradation permits a daily dosing cadence, which allows for sustained engagement of the GHRH receptor. This contrasts sharply with native GHRH, which would require much more frequent administration to achieve a similar exposure profile. When planning documentation for a research project, this daily cadence is a key parameter to schedule and record. For calculation purposes, a 5 mg vial reconstituted with 2 mL of diluent contains 2.5 mg per mL. A 1 mg illustrative dose is therefore calculated as 0.4 mL or 40 units on a standard U-100 insulin syringe, often documented on a daily cadence.
Common Tesamorelin mistakes to avoid
- Assuming the per-dose volume and syringe draw will be as small as sermorelin's and failing to plan for a larger subcutaneous injection.
- Neglecting to systematically document and rotate injection sites, which can lead to localized lipohypertrophy that interrupts a planned daily schedule.
- Mistaking the typical milligram (mg) dose for micrograms (mcg) in the calculator, leading to a thousand-fold dosing error.
- Attempting to reconstitute a 5 mg vial with an excessively small diluent volume, making the large 1 mg dose difficult to measure and draw accurately.
- Administering the daily dose in the evening by default, contrary to the morning administration schedule used in the vast majority of published clinical trials.
- Mistaking the trans-3-hexenoyl modification for a simple carrier or delivery system, rather than the specific chemical shield it is.
- Failing to distinctly log the molecule as tesamorelin, instead using the generic term 'GHRH', which obscures the critical stability difference in protocol review.
- Neglecting to record whether the tracked material is the pharmaceutical product Egrifta or a research-grade compound, a distinction vital for data integrity.
