Black market is primary source of all doping products

David Howman, the CEO of the WADA, considers that China is the chief source of raw materials used by underground labs for manufacture of anabolic steroids, HGH and other related drugs. Raw powders are shipped from this country. Then underground labs produce illegal products which are offered for sale by dealers at gyms and on the streets.
The black market of steroids controls sales of illegal medicines on the white market. The black market turns out to be the source of drugs that are available on the white market. It is believed that almost all products which are sold have been initially obtained from underground labs which have utilized raw materials from China.
Top athletes are often demonized for application of steroids and other related preparations. Since steroid scandals appear daily, many individuals believe that steroids and other doping products are mainly administered by top sportspersons. But it is important to mention that this a wrong opinion. Some specialists have defined that steroids and other related medicines are more widely used by high school students and aged individuals that try to improve their appearance. While students want to increase muscles with the help of steroids and some other illegal drugs, aged individuals try to add strength and lower fat deposits with the help of these drugs.
Unfortunately, legal supplements often contain steroidal compounds. Companies include such ingredients intentionally. As a result, those that take just nutritional and/or sport supplements turn out to be dopers. According to David Howman, the director general of the WADA, it is important to supervise supplement industry in order to prevent appearing of supplements which contain illegal compounds.
