In earlier days atheletes use to eat raw testicles to enhance their performance in sports activities and now-a-days atheletes are using steroids to enhance their performance in sports activities (doping). So, their current image is negatively builded as abusable drugs. These steroids are organic compounds which are chemically altered to mimic hormone testosterone, these are called as “Synthetic steroids”. “Natural Steroids”, are the organic compounds which are NOT chemically altered, that mimics hormones, and obviously the hormone it mimics is testosterone. Natural Steroids are involved in a wide range of physiologic processes, including stress response, immune response, carbohydrate metabolism, protein catabolism, blood electrolyte levels, and in the regulation of inflammation, and behavior.
