UFC middleweight Marc-Andre Barriault tested positive for a low level of the banned substance Ostarine following his June 20 victory in Las Vegas over Oskar Piechota, but denies knowingly taking any performance enhancing drug and suggested it could be due to a tainted supplement.

In a statement, Barriault said he tested positive for 190 picograms of Ostarine, which is equivalent to 190 parts per trillion. At that level, there is no performance-enhancing benefit for Ostarine, which is a Selective Androgen Receptor Modulator (SARM).

The UFC no longer announces the results of positive tests until there is an adjudication and leaves it up to the athlete. Barriault released the following statement professing his innocence:

Following a communication from the Nevada State Athletic Commission last week, I wanted to clarify the current situation to all my fans, the medias and everybody involved in the sport of mixed martial arts.

I was notified last week that an in-competition sample that I provided to the NSAC the night of my last fight on June 20th, 2020 was positive for an extremely low level (approximately 190 picograms or 190 parts per trillion) of the prohibited substance, Ostarine. First and foremost, I want to make things crystal clear, I did not intentionally use Ostarine, nor have I ever knowingly used any prohibited substance in my career. Since the beginning of my professional career, I have been tested three times by the Quebec athletic commission, and a total of seven times under the UFC/USADA program and have always tested negative.

Since I found out about this last week, I have learned quite a bit about Ostarine, specifically that it is commonly found as a low-level contaminant in certain dietary supplements, often at levels that provide absolutely no performance enhancing benefit. I strongly believe that a supplement contaminant is the reason for my low-level positive, and I am actively working with the UFC on reviewing and testing supplements that I have used prior to my June 20th fight, in the hope of identifying the culprit.

While I am extremely disappointed in this development, I am looking forward to finding a definitive explanation for my low-level positive test, to fully cooperating with the NSAC and to getting back to work in the Octagon soon.

Barriault is 12-4 overall in MMA and 1-3 in the UFC.
