It is there: Pseudo-ephedrine occurs naturally as plant alkaloid It was synthesized early part of lost century by several chemists from B-ethoxy amines , like Spath , Gohring etc . It is illegal to use as sports enhancer , abuse is dangerous and lethal , easily converted to meth-amphetamine . Stay away
