Protecting the Right to Enjoy Doping-Free Sport


Weightlifter banned following anti-doping rule violation

UK Anti-Doping has confirmed that British weightlifter Jonathan Bullough has been suspended from sport for 12 months following an anti-doping rule violation.

Mr Bullough tested positive for methylhexaneamine (MHA) following an in-competition test on 24 November 2012 at the British Weight Lifting Association Northern England Championships and was provisionally suspended from on 18 December 2012.

The athlete is banned from all competition from 24 November 2012 to 23 November 2013. Results obtained on 24 November 2012 from the Northern Open are disqualified. The full written decision can be found on the UK Anti-Doping website at

UK Anti-Doping Director of Legal Graham Arthur said: “Mr Bullough was able to explain how the prohibited substance entered his system, in that he was given a free sample of the supplement ‘Warrior Blaze’ which contains the listed ingredient “1,3-Dimmethylamylamine (Geranium Stem)”. This is a synonym of MHA.

“However he failed to recognise the potential risks to athletes of using supplements and did not conduct the necessary checks before using this product. This is yet another inadvertent doping finding related to the banned substance MHA and serves as a reminder to all athletes that they must take the utmost caution to avoid ingesting a prohibited substance.”

Notes to Editors:

Methylhexaneamine (MHA)
Methylhexaneamine is banned in competition under category S.6b, Specified Stimulants. MHA is frequently found in nutritional supplements which claim it can promote mental and physical performance, and aid weight loss. Methylhexaneamine can be listed in ingredients under a variety of names including 1,3-dimethylamylamine or DMAA, and a variety of geranium derivatives.
In August 2012, the Medicines and Healthcare products Regulatory Agency (MHRA) ruled that products containing methylhexaneamine needed to be removed from the UK market amid concerns of potential risks to public safety. For the full story click here.
