Dennis Siver points to new nutrionist for failed drug test

Esther Lin, MMA Fighting

Dennis Siver has broken his silence regarding his recent failed drug test.

The Nevada Athletic Commission announced on March 15 that the German fighter tested positive for the banned substance human chorionic gonadotropin (hCG) following his unanimous decision win over Manny Gamburyan at UFC 168 on Dec. 28.

Most commonly known as a female fertility drug, hCG is typically used by steroid users in an effort to restart their testosterone production following steroid usage.

While the NAC has yet to hand the 35-year-old Siver (22-9) a formal punishment or fine, Siver recently released a statement in German to groundandpound.de. The translated statement is below:

Today I would like to issue a public statement and give my fans and supporters the opportunity to form their own opinion on how the alleged doping allegations against me came about.

Last fall, my coach Niko Sulenta was diagnosed with severe cancer, which lead to me being on my own during the preparations for a UFC fight for the first time, without me being able to draw on his longstanding care and advice. Niko has always been essential to my weight reduction.

So prior to UFC 168 I had to hire an external personal trainer and nutritionist to support me with making weight. The nutritionist recommended me a new diet method from the US, which had been successfully used by the stars.

Thereupon I asked, if I, as a competitive professional athlete, could safely use this supplement. This was confirmed to me. Then I committed the fatal mistake of not making sure through the UFC if individual substances from the supplement could have effects on the drug tests.

I flew to the US and won my fight. I was all the more shocked when the result of the A sample was deemed ’inconclusive’ and I was hoping for the result of the B sample. They found a small component of hCG in my urine sample – a minor ingredient of the diet preparation and a substance which is banned in the UFC.

I do not want to blame anyone for this result and I take full responsibility for my gullible and careless behavior. It was my mistake and it was grossly negligent. But I distance myself from any kind of doping. In my previous sixteen UFC fights, not even the smallest banned substance has been detected. This makes the current events all the more disappointing and shocking for me and my team.

The UFC is returning to Berlin on May 31. It remains unclear whether Germany's most famous UFC fighter will be able to fight on the card in light of the recent failed drug test.
