If the failed drug test of  Cristiane “Cyborg” Santos was not a big enough blow to the Strikeforce roster, the latest fighter to test positive for alleged steroid use will surely not help the promotion.

It has been reported by MMA Junkie that Muhammed “King Mo” Lawal has tested positive for a banned substance following his second-round TKO victory over Lorenz Larkin at Strikeforce: Rockhold vs. Jardine.

The Nevada State Athletic Commission stated in an email that Lawal tested positive for Drostanolone. The substance is an injection that was originally designed to fight breast cancer. One of the side effects of the drug is that retention of water, gynecomastia and fat do not come in to play when it is used, which has made it very popular among athletes who wish to lose weight rapidly. The only downside is that is does have side effects, which include oily skin, acne, body/facial hair growth, aggression and accelerated hair loss. In order for the drug to be effective, injections must be taken every three to four days to maintain a constant level of the drug in the user’s blood.

The MMA Corner was able to get in contact with Lawal once the news of the failed drug test was made public. According to Lawal, he has not heard anything from the NSAC at the time of the conversation. Also, according to the Twitter account of  MMA Weekly staff writer Erik Fontanez, Lawal stated that he did not take any banned substances and has no clue what Drostanolone is.
