【Substance Alert】 Methylhexaneamine in Supplements

Due to the recent positive cases involving Methylhexaneamine found in Hong Kong athletes, HKADC again strongly urge athletes to check any supplements they may be using as to whether these products may contain the Prohibited Substance Methylhexaneamine. Methylhexaneamine is classified as a stimulant on the WADA 2012 Prohibited List and is prohibited in-competition.

Methylhexaneamine is commonly labeled under different names and for example could be found labeled as “1,3-dimethylamylamine” in the supplement “Jack 3d”. Various names of Methylhexaneamine include:

thylhexanamine Geranamine 2-hexanamine,4-methyl-(9CI)
1,3-dimethylamylamine Geranium oil, extract 1,3-dimethylpentylamine
dimethylamylamine (DMAA) dimethylpentylamine Pentylamine
Forthan 4-methyl-2-hexanamine Forthane
4-methylhexan-2-amine 4-methyl-2-hexylamine Floradrene
2-amino-4-methylhexane 1,3-dimethylamylamineforthane dimethyhexaneamine


Under the principle of strict liability, athletes are responsible for any substance found in their body. Therefore, athletes using supplements do so at their own risk and must exercise the utmost caution in checking the contents of supplements.
