Dillian Whyte of EnglandMarch 28 - A two-year ban on British boxer Dillian Whyte, one of the few fighters to Olympic super heavyweight champion Anthony Joshua, has been upheld by UK Anti Doping, it was announced today.

The 24-year-old (pictured top, right) tested positive for methylhexaneamine (MHA) – a substance frequently found in nutritional supplements which can promote mental and physical performance – in an in-competition test in October last year following his victory over Hungary's Sandor Balogh and was provisionally suspended in November 2012.

The stimulant was found in the dietary supplement Jack3d, a controversial workout booster also linked to the death of British London Marathon runner Claire Squires in, which was only removed from shelves in the United Kingdom last August.

Despite accepting Whyte's appeal in which he claimed he did not knowingly take MHA, the independent National Anti-Doping Panel found that the boxer did not do enough to check the product including failing to seek professional and medical advice before using the product which he brought over the counter.

Consequently, they found that Whyte had "failed to discharge the burden of establishing that he was not significantly at fault" and therefore his two-year punishment was imposed and could not be reduced.

UK Anti-Doping hopes the violation will be a warning to all athletes to be more vigilant when buying dietary supplements, it claimed.

"In August 2012, the Medicines and Healthcare products Regulatory Agency ruled that products containing methylhexaneamine needed to be removed from the UK market," said Nicola Newman, UK Anti-Doping director of communications and education.

"The fact that Mr Whyte purchased a product containing this ingredient after that date should remind all athletes that they need to be vigilant when considering supplementing their diet.

"The appeal panel highlights the need for athletes to make appropriate checks before using supplements, including consulting the website"

Whtye, who beat Joshua during his amateur career, tweeted after the verdict: "Don't worry. I will be back stronger and much more educated."

The young star from Brixton nicknamed Dillian "The Villain" Whyte seemed unstoppable as his impressive form saw him win nine bouts in a row since turning professional in 2011 and was a hot prospect.

In his run, Whyte beat the likes of Luthanian Remigijur Ziausys and seasoned veteran Hastings Rasani of Zimbabwe, as well as being the sparring partner of choice by Dereck Chisora, David Haye and Vitali Klitschko.

However, the violation means his victory over Hungary's Sandor Balogh will be disqualified.

Whyte's ban will run from October 2012 until October 12 2014.
