In August 1996, the FDA approved HGH for use in adult patients. Before this, it was only authorized for use by children who were HGH deficient, i.e. dwarfism, to promote growth.
HGH injections are still only available via a prescription from a doctor. However, HGH releasers like GenF20 Plus® don’t actually contain HGH. They encourage your body to produce more of its own HGH.
So you don’t require a prescription. The FDA permits HGH Releasers under the Dietary Supplement Health and Education Act of 1994.*
