Following Nesta Carter’s adverse test, here is what we know about Methylhexanamine or dimethylamylamine:
Methylhexanamine or methylhexamine, commonly known as 1,3-dimethylamylamine or simply dimethylamylamine was developed in 1948 as a Nasal Decongestant. It is a stimulant that has been added to the list of banned substances by WADA.
According to the Drug Foundation’s (New Zealand) website, the compound also called geranamine or DMAA, is “an organic chemical compound manufactured as a synthetic powder”. It is said to be in the same class as Ephedrine and structurally similar to amphetamine, leading to false positives. Athletes were warned to stay away from the compound to prevent false positive for amphetamine.
One Fobes Magazine (online) article in April 2013, linked DMAA with “seizures, arrhythmias, heart attacks, strokes, panic attacks, and deaths”. It is said to significantly raise blood pressure but had no impact on heart rates and in one study, with cerebral haemorrhaging.
Dimethylamylamine is reportedly used mainly as a fat burner and it is this fat-burning potential that made it attractive to makers of many brand name supplements.
Today, dimethylamylamine, which is sold as a dietary supplement, is also used for attention deficit-hyperactive disorder (ADHD), weight loss, improving athletic performance, and bodybuilding. Some manufacturers claim that dimethylamylamine naturally comes from rose geranium, geranium oil, or geranium stems on the label however the US Food and Drug Administration (FDA) believes this product is manufactured.
Methylhexanamine or dimethylamylamine was added to the World Anti-Doping Agency’s prohibited substances list for 2010.
