I would suggest reading the DILUTION STICKY and follow it to a T. EXERCISE as much as you can UNTIL about Saturday morning. You may want to start eating red meat a day or two before your test, but refrain from exercising within that same 2 days. Also, in that last 2 days eat low fiber and high fat. There's plenty more hints given in this forum with some time reading. Good luck and please post your results of your test.
