Tesamorelin

Growth Hormone & Muscle Weight Loss & Metabolic Energy & Vitality

5mg vial + 1.25mL BAC water = 35 units = 1.4mg — Amounts listed in the Dosify Me data: 1.4mg (current FDA label dose) — Frequency: daily — Best taken: bedtime, ≥90 min before eating (empty stomach)

Amounts and schedules here are listed from the Dosify Me compound data (sources below). They are not recommendations: Dosify Me does not tell you what dose to take, so follow your prescriber.

Reconstitution

Vial sizes up to 10 mg are mixed to 4 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.

5 mg1.25 mL4 mg/mL
10 mg2.50 mL4 mg/mL
20 mg*3.00 mL6.67 mg/mL

* This size is conventionally mixed more concentrated rather than diluted further — fewer units per dose than smaller vials of this peptide.

Dose to syringe units

On a standard 100-unit (1 mL) insulin syringe, for vials mixed to 4 mg/mL (sizes marked * are more concentrated and need fewer units):

Amounts listed in the Dosify Me data: 1400–1400 mcg. Frequency: daily. Timing: bedtime, ≥90 min before eating (empty stomach).

FDA-approved (as Egrifta SV) for HIV-associated lipodystrophy at this exact dose — the current label mixes to 4mg/mL (a 2mg single-dose vial + 0.5mL diluent) and delivers 1.4mg in 35 units. Injection sites are rotated to reduce lipoatrophy risk. The 5mg and 10mg compounded-vial options here also mix to that same 4mg/mL; the 20mg option is capped at 3mL BAC water instead, so it comes out more concentrated (fewer units per dose). The FDA-approved label uses continuous daily dosing with no scheduled break. Separately, off-label wellness-community protocols commonly cycle it — roughly 60-90 days on, then about 30 days off — to reduce pituitary receptor desensitization. This app defaults to daily to match the approved label.

Reading units for Tesamorelin

Check one row of the table above: 1400 mcg is 1.4 mg; 1.4 mg ÷ 4 mg/mL = 0.35 mL; 0.35 mL × 100 = 35 units.

Side effects

Medication caution

The FDA label warns tesamorelin can raise blood sugar and may unmask or worsen diabetes, working against insulin and other diabetes medications. Raising growth hormone can also unmask previously hidden hypothyroidism and shift how the body converts thyroid hormone, so anyone on thyroid medication should have levels monitored (especially in the first 6 months). Talk to your prescribing doctor before combining.

Frequently asked

How many units is 1.4 mg of Tesamorelin?

At 4 mg/mL (the standard mix for vials up to 10 mg), 1.4 mg of Tesamorelin is 35.0 units on a 100-unit insulin syringe (0.350 mL).

How much bacteriostatic water do I add to a 5 mg vial of Tesamorelin?

1.25 mL, which gives 4 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.

How much bacteriostatic water do I add to a 10 mg vial of Tesamorelin?

2.50 mL, which gives 4 mg/mL. Larger vials hold at most 3 mL of water, so they are mixed more concentrated and need fewer units per dose.

How much bacteriostatic water do I add to a 20 mg vial of Tesamorelin?

3.00 mL, which gives 6.67 mg/mL. This size holds at most 3 mL of water, so it is mixed more concentrated and the same dose is fewer units than from a smaller vial.

How often is Tesamorelin taken?

Daily. Bedtime, ≥90 min before eating (empty stomach) Typical cycle: 12–16 weeks on, ~4 weeks off; repeat 1–2×/year.

Published by San Tan Group, LLC, the company that makes the Dosify Me app. About Dosify Me

Figures come from the Dosify Me compound database for Tesamorelin: concentration is the vial amount ÷ the water volume, and syringe units are the volume in mL × 100 on a U-100 syringe.
