The supplement that was taken by Lawal contained the synthetic steroids Superdrol and Promagnon

King Mo Lawal admitted that he had used a dietary supplement that was tainted. As it turned out to be, that supplement contained 2 ingredients that were synthetic steroids. According to this person and his manager, consumption of this product led to positive for Masteron.
Lawal noted during an interview for MMA Hour that he had bought “S-Mass Lean Gainer” in a Max Muscle store in April, 2010. This product was manufactured by Steel Body Production.
But this is not the situation, when steroid ingredients are not disclosed. Synonyms of prohibited drugs are listed on the label of S-Mass Lean Gainer. In fact, these steroids were the subjects of some debates between anti-doping agencies 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 medications 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 defined in the urine sample of King Mo Lawal by a proper lab of the anti-doping agency.
The pharmaceutical company Anabolic Resources was the first which sold Superdrol as a dietary supplement. It was over 5 years ago. This company was accused in elaborating of a new unapproved drug. Later Anabolic Resources pleaded guilty and admitted that they had marketed a synthetic steroid as a dietary supplement.  As a result, this 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 the company for manufacturing and selling this steroid. But this pharmaceutical company decided to stop manufacturing this steroid in 2006.
Although legal status of these two products is controversial, numerous companies have manufactured and distributed them as dietary supplements during about 6 years. Undoubtedly, persons who are involved in this industry know about the status of these products but they continue to sell them.
The manager for Lawal notes that the full responsibilities must be taken by the companies which market synthetic steroids as dietary supplements. He believes that such companies misguide users intentionally.
