Growth hormone-releasing hormone analog

Tesamorelin reconstitution.

Tesamorelin is the only FDA-approved GHRH analog for body composition. Compounded research vials are typically 1-5 mg. With 2 mL bacteriostatic water, the standard 1-2 mg daily dose lands cleanly on the syringe.

Tesamorelin specifics

What to know about this peptide.

Half-life

Half-life ~30 minutes for parent compound but downstream IGF-1 elevation lasts 24+ hours. Daily injection standard.

Stability after mixing

FDA-approved version comes pre-measured. Compounded versions: refrigerate at 2-8°C, use within 28 days.

Typical use

Visceral adipose reduction, IGF-1 elevation. FDA-approved for HIV-associated lipodystrophy; used off-label for body composition.

Not medical advice

The math on this page is correct for the listed vial and BAC-water volume. The decision to reconstitute and inject Tesamorelin belongs to you and a clinician who knows your full history — not to a webpage.

Frequently asked

Tesamorelin questions

What vial size is Tesamorelin usually sold in?

Tesamorelin most commonly ships as 1 mg or 2 mg or 5 mg of lyophilized powder. The standard reconstitution is 2 mL of bacteriostatic water, which yields clean unit-mark math on a U-100 insulin syringe for the doses used in most protocols.

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

The standard volume is 2 mL of bacteriostatic water. You can use more (easier to draw, lower concentration) or less (more concentrated, smaller draw volume) without changing the peptide itself — only the syringe math changes. The dose table on this page is pre-calculated for 2 mL.

What is the half-life of Tesamorelin?

Half-life ~30 minutes for parent compound but downstream IGF-1 elevation lasts 24+ hours. Daily injection standard.

How long does reconstituted Tesamorelin last in the fridge?

FDA-approved version comes pre-measured. Compounded versions: refrigerate at 2-8°C, use within 28 days.

What is Tesamorelin typically used for?

Visceral adipose reduction, IGF-1 elevation. FDA-approved for HIV-associated lipodystrophy; used off-label for body composition.

What syringe should I use for Tesamorelin?

U-100 insulin syringes (29–31 gauge, 8–13 mm needle) are standard for subcutaneous peptide injection. Each unit on a U-100 syringe equals 0.01 mL. The dose table above shows how many units to draw for each common dose, given the vial size and standard bacteriostatic water volume.
