Fun truth is that aspartime is not toxic at all in the amount's we consume. When artificial-sweeteners were invented, some bunch of fucking hippies instantly started to attack them, and that caused artificial sweeteners to get such a bad name. I relay my claims on a guy that I trust. Scott Abel is his name and his been into building muscle for a long time. He opposes basically all suplements (except creatine) and has spoken against current pro-bodybuilding drug mentality.
