Geranium oils do not contain DMAA
Geranium oils do not contain the stimulant DMAA-MHA, according to this big hitting research study that again questioned much cited research claiming it does.
“These studies as well as closer scrutiny of the original publication by Ping et al show that geranium oils do not contain methylhexaneamine and the use of the name Geranamine for this compound appears to have been a marketing ploy which has resulted in a large number of athletes returning adverse findings,” they wrote in the journal Drug Testing and Analysis.
“Other stimulants used in supplements can also cause adverse findings and the status of compounds such as a and b-phenethylamine as doping agents needs to be determined.”
The researchers, led by Angelo Lisi from the National Measurement Institute in Australia, also said the status of another “doping agent” called a and b-phenethylamine needed investigating.
