I thought HGH cost $20,000 per year for treatment?

If you want large doses of injectable HGH, then it could possibly cost that much. However, that figure is generally quite high even for injectable hgh. A more reasonable estimate is $3,000-$5,000, depending on where you purchase it from. However, if you supplement with hgh in a pill or spray form, a year's supply can be between $300 and $1000.
