Numerous synthetic steroids are marketed as dietary supplements

King Mo Lawal acknowledged that he had administrated a dietary supplement which was tainted. As it turned out to be, that supplement contained 2 ingredients that were synthetic steroids. According to this fighter and his manager, consumption of this product led to positive for Masteron.
King Mo Lawal noticed during an interview for MMA Hour that he had purchased “S-Mass Lean Gainer” in a Max Muscle store in April, 2010. This supplement was produced by Steel Body Production.
But this is not the situation, when steroid ingredients are not written. Synonyms of banned preparations are enumerated on the label of S-Mass Lean Gainer. In fact, these steroids were the subjects of some debates between anti-doping organizations and federal regulators since 2005. They are following:  2a-17a-Dimethyl-5aandrost-3-one 17b-ol and 4-Chloro-17a-Methyl-a-andro4-ene3, 17b-diol. These drugs are better known under the names: Superdrol and Promagnon.
As for Superdrol, it goes by methyldrostanolone, methasteron and 2a-17a-Dimethyl-5aandrost-3-one 17b-ol. So, methylated version of Masteron was determined in the urine sample of King Mo Lawal by a proper lab of the anti-doping agency.
Anabolic Resources, a pharmaceutical company, was the first which manufactured Superdrol as a dietary supplement. It was over 5 years ago. This company was accused in introducing of a new unapproved drug. Later Anabolic Resources pleaded guilty and acknowledged that they had sold a synthetic steroid as a dietary supplement.  As a result, this pharmaceutical company had to pay a fine of 500, 000 dollars.
As for Promagnon, it also originally appeared as a dietary supplement in 2005 by Peak Performance’ Labs. The government didn’t take any action against this company for producing and selling this steroid. But Peak Performance decided to stop producing this product in 2006.
However legal status of these two substances is controversial, a lot of companies have manufactured and sold them as dietary supplements during about 6 years. Undoubtedly, those who are involved in this industry know about the status of these steroids but they continue to sell them.
The manager for Lawal says that the full responsibilities must be taken by the companies which market synthetic steroids as dietary supplements. He adds that such companies misguide people intentionally.
