Tesamorelin Dosage Chart
Dosing & Reconstitution Guide
20 mg vial calculations and four reconstitution steps
Phase 3 Research Schedule (3.0 mL = ~6.67 mg/mL)
| Research Period | Daily Dose (mg / mcg) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–26 | 2 mg / 2000 mcg | 30 units (0.30 mL) |
Frequency: Once daily by subcutaneous injection. Phase 3 trials evaluated 2 mg daily for 26 weeks, with extension data through 52 weeks.[3] This research schedule is distinct from the current EGRIFTA SV label, which uses a different formulation and dose.
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl until dissolved. Do not shake.
- Label with the compound, concentration, and preparation date; refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
Storage note: Bacteriostatic water does not establish a universal use-by period. Follow the exact product label and formulation-specific stability instructions.

Tesamorelin Vial and Research Context
- Reconstitute: Add 3.0 mL bacteriostatic water per 20 mg vial → ~6.67 mg/mL concentration.
- Phase 3 research amount: 2 mg (2000 mcg) once daily by subcutaneous injection for 26 weeks.[3]
- Easy measuring: At 6.67 mg/mL, 1 unit = 0.01 mL ≈ 66.7 mcg on a U-100 insulin syringe.
- Storage: Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F); reconstituted: refrigerate and follow the exact formulation’s validated use-by period.
Tesamorelin is a synthetic 44-amino-acid peptide analog of Growth Hormone-Releasing Hormone (GHRH)[1]. It stimulates endogenous growth hormone release and raises IGF-1 levels, leading to enhanced lipolysis and metabolic benefits[2]. Tesamorelin is FDA-approved for reducing visceral adipose tissue in HIV-associated lipodystrophy and is studied for metabolic disorders and aging research[3][4].
Tesamorelin 20 mg Calculation Context
A 20 mg vial describes total nominal vial content. It does not replace the amount assigned to one administration. With the page’s unchanged 3.0 mL final volume, the concentration is approximately 6.67 mg/mL. The cited phase 3 amount of 2 mg therefore occupies 0.30 mL, or 30 U-100 syringe units.[3]
This strength-specific peptide dosage calculator is a reconstitution-math aid for the same family schedule, not a separate dosing protocol or a prescribing tool.
Ten-Dose Nominal Vial Yield
Twenty milligrams divided by the 2 mg research amount equals 10 nominal 2 mg calculations. At 6.67 mg/mL, each calculation is 0.30 mL. The result is mathematical vial yield; it does not establish sterility, recovery, potency, or a discard date after reconstitution.
The supplier listing documents the 20 mg product identity and destination, not the clinical schedule.[11]
Measurement and Research Records
Record the prepared concentration as Tesamorelin 6.67 mg/mL, along with the preparation date, vial identifier, diluent lot, 30-unit marking, 0.30 mL volume, 2 mg mass, study day, and documented injection site. Follow the exact product documentation for storage and discard timing.
Tesamorelin 20 mg Dosage Calculation: 3 mL and 30 Units
This calculator-style tesamorelin 20 mg dosage page uses the concentration already established in the primary chart. Dividing 20 mg by 3.0 mL gives approximately 6.67 mg/mL. A U-100 insulin syringe is marked by volume: one unit equals 0.01 mL. At this concentration, each unit represents about 66.7 mcg.
- 1 mg: 15 units (0.15 mL).
- 2 mg: 30 units (0.30 mL).
- Full vial: 20 mg in 3.0 mL.
For this dosage calculator, 3.0 mL of bacteriostatic water is the fixed final-volume input. The calculation moves in both directions: 30 units multiplied by 0.01 mL equals 0.30 mL, and 0.30 mL multiplied by 6.67 mg/mL is approximately a 2 mg tesamorelin dose. U-100 syringe units are volume markings, not peptide international units.
Phase 3 Schedule Stays the Same Across Vial Strengths
The schedule shown in Cards 01–03 remains unchanged: 2 mg by subcutaneous injection once daily for 26 weeks. The pooled phase 3 analysis used that amount and duration and reported extension observations through 52 weeks.[3] The two phase 3 trials and their extensions define the research protocol summarized here. A separate randomized trial and extension likewise evaluated 2 mg each day and found that visceral-fat improvements were maintained in participants who continued daily tesamorelin, while the earlier change was lost after switching to placebo.[12]
A 20 mg vial changes the reconstitution math, draw volume, syringe marking, nominal number of calculations, and supply counts. It does not create a loading phase, escalation, taper, or different frequency.
20 mg Vial Yield and Supply Planning
At the displayed 2 mg research amount, one 20 mg vial has a nominal yield of 10 administrations. The supplies card applies that arithmetic to 8, 12, and 16 weeks and rounds vial quantities upward so a partial vial is never counted as a complete one. Daily administration also means one new syringe and two alcohol swabs per study day.
Bacteriostatic-water totals use 3.0 mL per vial. These planning values are tied to this page’s inputs; changing the final volume or displayed research amount requires recalculating concentration, U-100 units, mL, vial counts, water totals, and nominal yield together.
Nominal yield should not be read as proof that every theoretical administration can be recovered from a vial. Real-world preparation can involve dead space, handling loss, and product-specific stability limits.
The 20 mg Research Vial Is Not EGRIFTA SV
EGRIFTA SV is a specific FDA-approved 2 mg single-dose vial supplied with sterile water. The FDA label describes a 1.4 mg once-daily dose, a 0.5 mL reconstitution volume, and immediate use after preparation.[7] Tesamorelin is a prescription drug in that approved-product context. Those directions are formulation-specific and do not transfer to a separately supplied 20 mg vial.
This page instead translates the 2 mg amount evaluated in phase 3 research into a 20 mg vial calculation based on a 3.0 mL final volume. It does not substitute the vial strength, diluent, labeled dose, injection volume, storage period, or discard instructions of one formulation for another.
Human Evidence for Visceral Abdominal Fat
In a randomized trial of 412 adults with HIV and abdominal fat accumulation, daily subcutaneous tesamorelin for 26 weeks reduced visceral adipose tissue by 15.2%, while the placebo group increased by 5.0%. Triglycerides and the total-cholesterol-to-HDL ratio also improved in the tesamorelin group.[10]
The pooled phase 3 analysis reported a reduction in visceral adipose tissue and maintenance of that reduction during continued treatment through the 52-week extension.[3] A responder analysis associated an 8% or greater visceral-fat reduction with selected changes in triglycerides, adiponectin, and glucose-homeostasis measures.[14]
These outcomes apply to the defined clinical populations and study designs. They do not make a 20 mg vial a general weight-loss product, and the current EGRIFTA SV label states that it is not indicated for weight-loss management.[7]
Liver Fat, Metabolic Findings, and Study Limits
A six-month randomized study in antiretroviral-treated adults with HIV and abdominal fat accumulation used 2 mg daily and reported reductions in visceral and liver fat compared with placebo. An early fasting-glucose difference was not sustained as a significant between-group difference at six months.[13]
A 12-month trial in people with HIV and nonalcoholic fatty liver disease reported a greater reduction in hepatic fat fraction with tesamorelin than placebo.[15] A later analysis among participants using integrase inhibitors reported reductions in visceral and hepatic fat without evidence of worsened glycemic control in that subgroup.[16]
Another randomized study evaluated 1 mg and 2 mg amounts in people with type 2 diabetes for 12 weeks and did not find a significant between-group change in overall glycemic control.[4] Population, duration, comparator, outcome definition, and formulation therefore matter when interpreting tesamorelin research.
Tesamorelin, GHRH, Growth Hormone, and IGF-1
Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH). It acts at receptors on pituitary somatotroph cells, stimulates the pulsatile release of growth hormone, and can increase circulating IGF-1.[1][2] This pathway differs from administering growth hormone directly.
The mechanism helps explain why clinical sources discuss IGF-1, glucose, fluid retention, and injection-site monitoring. Exploratory cognitive findings have also been reported in older adults, but they do not establish a tesamorelin dosage for cognitive enhancement, healthy aging, or use outside the studied populations.[5]
Subcutaneous Measurement, Injection Sites, and Sharps Safety
Clinical and prescribing sources describe subcutaneous injection in the abdomen with rotation of injection sites.[6][7] General subcutaneous technique includes cleaning the vial stopper and selected skin site, allowing the alcohol swab to dry, using a new sterile syringe and needle, and following the governing procedure for needle angle and administration.[9] Product-specific reconstitution instructions and discard timing still control for the exact formulation being handled.
- Verify the 30-unit U-100 marking and its 0.30 mL equivalent before recording the 2 mg calculation.
- Do not confuse U-100 volume markings with peptide IU.
- Rotate and document injection sites rather than repeatedly using one location.
- Place each used needle and syringe directly into an appropriate sharps container.
Tesamorelin Side Effects and Monitoring Context
Clinical and labeling sources identify injection-site reactions, fluid retention, joint or muscle symptoms, carpal-tunnel symptoms, hypersensitivity, elevated IGF-1, and glucose intolerance or diabetes risk as relevant considerations.[1][7][8] The label also lists contraindications that include active malignancy, pregnancy, disruption of the hypothalamic-pituitary axis, and hypersensitivity to the labeled formulation.[7]
Adverse-event frequencies and monitoring procedures belong to their cited population, study design, and product formulation. They are not a safety guarantee for a separately supplied vial or another research setting.
Tesamorelin 20 mg Dosage Frequently Asked Questions
How much bacteriostatic water does this 20 mg chart use?
The chart uses 3.0 mL, producing a concentration of approximately 6.67 mg/mL. This is a page-specific calculation input, not a universal direction for every tesamorelin formulation.
How many U-100 syringe units equal 2 mg?
At 6.67 mg/mL, 2 mg occupies 0.30 mL, which is 30 units on a U-100 insulin syringe.
How many 2 mg calculations are in a 20 mg vial?
Ten nominal calculations. That result is mass arithmetic only and does not determine sterility, recoverable volume, storage life, or permission to retain a prepared vial.
Does a 20 mg vial change the phase 3 dosing schedule?
No. The accepted family schedule remains 2 mg once daily for 26 weeks, with extension evidence through 52 weeks.[3] Vial strength changes the measurement and supply arithmetic, not the study-defined amount or frequency.
Is this 20 mg vial the same as EGRFFTASV?
No. EGRIFTA SV” is a different 2 mg single-dose formulation with its own supplied diluent, labeled 1.4 mg dose, preparation instructions, and immediate-use requirement.[7]
Can the 30-unit calculation be used with a different water volume?
No. The 30-unit result is specific to 20 mg in 3.0 mL. A different final volume changes concentration, mcg per unit, syringe units, and mL together.
Important Research Note
This tesamorelin 20 mg dosage page translates a published research schedule into strength-specific concentration, U-100 syringe units, mL, nominal vial yield, and supply planning for research use. It does not establish an individualized regimen, validate a product-specific storage period, or constitute medical advice.
