HGH Calculator
Convert HGH vial IU and BAC water into your exact syringe draw. HGH is measured in international units (IU), not micrograms.
HGH (somatropin) is measured in international units (IU), not micrograms or milligrams. This is because biological activity — not weight — determines dosing.
The standard conversion is 1 mg ≈ 3 IU for pharmaceutical-grade somatropin. This means a 10 IU vial contains approximately 3.33 mg of HGH.
Lyophilized (powder): Store refrigerated at 36–46°F (2–8°C). Stable for months. Some formulations can be stored at room temperature short-term, but refrigeration extends shelf life significantly.
Reconstituted: Must be refrigerated. Use within 14–21 days when reconstituted with bacteriostatic water. Use within 24 hours if reconstituted with sterile water (no preservative).
Never freeze reconstituted HGH. Freeze-thaw cycles denature the protein and destroy potency. Do not shake the vial — gently swirl until dissolved.
In research literature, HGH protocols typically fall into these ranges:
General research (2–4 IU/day): The most commonly studied range. Typically administered as a single subcutaneous injection, often in the morning or before bed.
Advanced research (4–8 IU/day): Higher doses are sometimes split into two daily administrations (e.g., morning + afternoon) to better mimic natural pulsatile secretion patterns.
Timing considerations: Research protocols often administer HGH fasted, as elevated blood sugar and insulin can blunt the GH response. Some protocols alternate 5 days on / 2 days off.
