Hey as far as the asprin goes I also got white willow bark extract and well some people said go with that instead of just plain Aspirin but I am concerned of finding a way to keep the life of the ephedrine in effect for at least 4 hrs by 3 or 2.5 hrs it starts to fade. So again anyone have any idea to really make this more stronger? Right now its Lipo-6 and Bronkaid and White Willow. Any suggestions are welcomed plz give feedback thnx guys.
