How to Use This Calculator
Check your vial size
HGH vials are typically labeled in IU. Common sizes are 10 IU, 24 IU, or 36 IU. Some brands list mg instead (multiply by 3 to get IU).
Add bacteriostatic water
A common rule is 1ml per 10 IU for easy math. For a 24 IU vial, 1ml works well. Inject water slowly against the vial wall - never shake!
Select your dose
Choose based on your goals. Start low (1-2 IU) and assess tolerance before increasing. Higher doses may require splitting AM/PM.
Read the syringe units

Important Safety Information
Human Growth Hormone is a prescription medication. This calculator is for educational purposes only. Side effects may include joint pain, water retention, carpal tunnel syndrome, and effects on blood sugar. Always use under medical supervision.
Frequently Asked Questions
According to the WHO standard, 1 mg of somatropin (HGH) equals approximately 3 IU. This is the universally accepted conversion. So a 10 IU vial contains about 3.33 mg of HGH, and a 36 IU vial contains about 12 mg.
Most protocols suggest injecting HGH in the morning before eating to mimic the body's natural growth hormone pulse. Some split larger doses (4+ IU) into morning and afternoon injections. Avoid injecting before bed as it may interfere with natural nighttime GH release.
When reconstituted with bacteriostatic water and refrigerated, HGH typically remains stable for 3-4 weeks. With sterile water (no preservative), use within 48-72 hours. Never freeze reconstituted HGH, and keep it away from light.
Pharmaceutical brands (Genotropin, Norditropin, Humatrope, Saizen) are all somatropin - the same 191 amino acid sequence. The differences are in delivery devices, formulations, and pricing. Generic HGH quality varies significantly - pharmaceutical-grade products ensure purity and proper potency.
