How to reconstitute HGH (Somatropin)

  1. Wipe both vial stoppers with a fresh alcohol swab and let them dry.
  2. Draw 2 ml of bacteriostatic water into a syringe.
  3. Insert the needle at an angle into the HGH (Somatropin) vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
  4. Do not shake. Gently swirl the vial until the peptide fully dissolves.
  5. Store the reconstituted vial refrigerated (2–8 °C / 36–46 °F) and use within roughly 28 days.
  6. Draw each dose to the unit mark shown above for your target 1000 mcg dose.

About HGH (Somatropin)

Human growth hormone (somatropin) is a recombinant version of endogenous GH. It is FDA approved for several deficiency and growth disorders and is widely studied for recovery, body composition, and anti-aging effects.

Half-life: Approximately 2–4 hours (recombinant, subcutaneous)
Typical dose range: 1–4 IU daily (approx 0.33–1.33 mg; 1 mg ≈ 3 IU)
Class: Recombinant human growth hormone (191-aa protein)

HGH (Somatropin) calculator FAQ

Is this a HGH (Somatropin) peptide calculator or a reconstitution calculator?

Both. This HGH (Somatropin) calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.

How much bacteriostatic water for a 6 mg HGH (Somatropin) vial?

This page is pre-filled with 2 ml of bacteriostatic water for a 6 mg HGH (Somatropin) vial because that is a common research ratio. You can adjust the water amount in the full calculator.

How many units is a 1000 mcg HGH (Somatropin) dose?

With the default 6 mg vial and 2 ml BAC-water ratio, the preview above calculates the U-100 syringe units for a 1000 mcg dose. Change the dose if your protocol uses a different amount.

Does this HGH (Somatropin) dosage calculator give medical advice?

No. It only performs unit math. Dosing, titration, and whether HGH (Somatropin) is appropriate are clinical decisions that should be made with a licensed healthcare professional.
