Noted this sentance in Colm O'Rourke's article yesterday in Sindo
''The substance which O'Sullivan tested positive for was from a tablet taken at half-time in the 2016 league final and is called methylhexaneamine which increases heart rate and blood pressure, is a muscle mass aid and a weight loss aid but is hardly something which is going to improve a forward like O'Sullivan's ability to kick points''.
It must be one fast acting chemical/drug , take it at half time and expect it to take effect ? If he wasn't supposed to have this drug, how come he was able to take it at half time in the dressing room ? Clearly, something acts faster than Anadin
