Note: Prescription-only in the US. FDA brand names: Genotropin, Norditropin, Humatrope, Omnitrope, Saizen. Dose expressed in IU (1mg ≈ 3 IU). Monitor glucose - HGH can induce insulin resistance.

Frequently Asked Questions

What is the standard HGH dose?

Standard: 1–2 IU daily to start, titrate based on IGF-1 response. Advanced: 2–4 IU daily split AM/PM. Check IGF-1 at 6 weeks. 1 IU ≈ 333mcg of somatropin.

How do I reconstitute HGH?

Add 1mL of bacteriostatic water to a 3.3mg vial of HGH to get a concentration of 3300 mcg/mL. This gives 667mcg per 20 units on a 100-unit insulin syringe.

What blood markers should I track while running HGH?

Common biomarkers tracked alongside HGH protocols include IGF-1 (primary - target upper quartile for age), IGFBP-3, Fasting glucose, Fasting insulin, HbA1c, ApoB, Thyroid panel. Establishing a baseline panel before starting and re-drawing labs at consistent intervals lets you measure changes against your own reference point, generic lab ranges are less informative than your personal trend over time. MyProtocolStack tracks each of these biomarkers in the context of your active HGH protocol.
