Anti-Doping and Illicit Drugs

The Rugby Football Union (RFU) condemns drug use in sport. It is harmful to the health of players, totally contrary to the spirit of rugby and the RFU is committed to protecting all players' fundamental right to participate in doping-free rugby.

The RFU identifies integrity, fairness, equity and respect as essential to success in rugby and we aim to protect rugby from being undermined by doping.

The RFU runs distinct policies and programmes for both anti-doping and illicit drugs.

Supplement warning – 1, 3-dimethylbutylamine (DMBA)

This substance may also be labelled as: Pouchung Tea extract; AMP citrate; 1,3-dimethylbutylamine citrate; 4-amino-2-pentanamine; Pentergy; 4-amino-2-methylpentane citrate; 4-AMP; 2-amino-4-methylpentane; and 4-methyl-2-pentanamine.

Players should be aware that DMBA is a prohibited substance and is banned In-Competition (on match day). It could lead to an Anti-Doping Rule Violation (ADRV) following an In-Competition drugs test.

Apart from exposing users to anti-doping violations, the use of supplements containing DMBA may also have significant health risks. DMBA has not been studied in humans, but it is known to have a similar chemical structure to MHA, which has been linked to high blood pressure, headaches, stroke, and has been implicated in the death of a marathon runner.

At the time of writing products that are reported to contain (or have contained) DMBA, include: Red Rum; Frenzy; Oxyfit Xtreme; OxyTHERM Pro; Redline White Heat and MD2 Meltdown. This is unlikely to be an exhaustive list.
