No need.Jackie Chan's have a coating around them that can interfere with some of the products absorbtion and allow them to pass through unmetabolized if that coating is not broken open.BTG's are standard tablets that will be absorbed perfectly after being swallowed whole.
For me personally,Ox caused stomach irritability if I took it on an empty stomach.Taking it with food alleviated the problem.Yes,split the dosages up so that your taking an even amount every 5-6 hours or so.
anyone ever split up thier var between vendors...For example, if I have both BTG's and Jakie Chan's (LOL @fin). I'm assuming it is ok to do say 15mg of the american stuff and 10mg of wongs in the same day.
