Updated London, 14 February 2013 –A significant number of athletes in a wide range of sports across the world have committed Anti-Doping Rule Violations by virtue of positive tests for methylhexaneamine (MHA), which is a prohibited stimulant.
This substance is known under several other names, including 4-methyl-2-hexanamine; 4-methyl-2-hexylamine; 2-amino-4-methylhexane; 1,3-dimethylamylamine; 1,3-dimethylpentylamine; 2-Hexanamine; 4-methyl- (9CI); Forthan; Forthane; Floradrene; Methylhexaneamine; Geranamine; DMAA. Athletes should avoid products that claim to contain any of these substances.
There are a number of products that are known to contain (or have contained) MHA, including Jack3d, Oxyelite Pro, Hemo Rage Black, Dexaprine, M5 Extreme, Muscle Meds Code Red, Lipo 6 Black, 1 M.R., DynaPep, Anarchy Covalex, Muscle Spike, Noxipro, Isatori PWR, Muscletech Neurocore, Muscletech Hydroxystim, Fahrenheit Nutrition Lean EFX, Muscle Warfare Napalm, SNI Nitric Blast, BIORhythm SSIN juice, Gaspari Nutrtion Spirodex, Spirodex, MethylHex42, Grenade Universal Grenade, M.A.P. (iovate) Arson, Geranamine, Tested Burner, Presurge Unleashed, Beta-Cret EXTREME, Hydroxystim, Mass Pump 3D and !Tight Xtreme. This is not necessarily an exhaustive list. Players are advised to avoid all products that contain MHA.
Players are also advised to exercise extreme caution when using any food supplement product, as these are often not subject to strict manufacturing controls, and may contain prohibited substances that are not declared on the label, or in different concentrations than stated on the label.
Not only may the use of such substances expose players to positive anti-doping tests, but also to significant health risks. MHA has been connected to high blood pressure, headaches, stroke, and has been implicated in the death of a marathon runner. The ITF produces a wallet card containing a range of anti-doping information, including the full WADA prohibited list, which players are advised to keep with them at all times in order to check (and/or get physicians to check on their behalf) the contents of all products that they ingest. The wallet card may be downloaded from the ITF Anti-Doping web site at www.itftennis.com/anti-doping.
Players are responsible for everything they ingest, and a positive anti-doping test cannot be excused by a contaminated supplement.
