Ansomone is a kind of sterile, lyophilized formulation of Recombinant Human Growth Hormone (HGH). It used to be 192 amino acid sequence (somatrem) but has since been changed to 191 amino acid (somatropin). Ansomone is derived from engineered E.coli bacteria, which then produce growth hormone identical to the human body's naturally produced HGH. Ansomone is indicated for growth failure due to endogenous growth hormone deficiency (GHD) and Turner disease or Kidney failure.

Pharmacology
Ansomone exerts the same actions of endogenous human growth hormone. It can stimulate proliferation and differentiation of epiphysis chondrocyte, stimulate growth of cartilage matrix cells, stimulate proliferation and differentiation of osteoblast; thus accelerate the linear growth rate and improve epiphysis width. Ansomone® can promote protein synthesis in whole body; reverse the negative nitrogen equilibrium caused by wound and surgery; correct the hypoproteinemia due to severe infection or hepatocirrhosis; stimulate synthesis of immunoglobulin and proliferation of lymphadenoid, macrophage and lymphocyte, thus enhance the ability of infection resistance; stimulate proliferation of collagen oocyte, fibroblast and macrophage in sites of burn and surgery, thus accelerate wound healing; promote synthesis of cardiomyocytes, thus improve cardiac contractility and reduce cardiac oxygen consumption; regulate lipometabolism, thus depress serum cholesterol and low density lipoproteins level; complement insufficiency or deficiency of growth hormone, regulate adults lipometabolism, osteo metabolism, heart and kidney function.

It is reported that the equal pharmacological effect could be achieved via subcutaneous (sc) or intramuscular (IM) administration. Even though SC may lead to a higher concentration of GH in plasma, IM also yields equal in crease of the IGF-l hormone levels.

Black market and counterfeit Ansomone

Between the years 2005 to 2007 Ansomone used to be abundantly available on the black market. It was technically not a black market, since growth hormone was not categorized as illegal then. Following Chinese government’s crackdown and temporary shutdown of most growth hormone manufacturers Ansomone has disappeared  from the market. In the recent years many counterfeit copies of Ansomone popped up on the internet. It is believed that most of it today is counterfeit.
