Omnitrope is a synthetic form of human growth hormone (HGH). HGH is a naturally occurring protein in the body; it stimulates growth of the bone and cartilage. Omnitrope is a recombinant protein, i.e. it is produced under laboratory conditions and is structurally almost identical to the natural HGH. It is an FDA-approved easy-to-use product, and is a cost-effective treatment for children with growth hormone deficiency.
