I'll try to answer your question based on my recommended way of taking those two products together, which work awesome together for burning fat! OK, I would take 4 caps of EPI-V per day (2 caps first thing in the morning and then another 2 caps as late in the day as long as it is 8hrs before you intend to sleep). With the PRO-XANTHINE, it is a little harder to say, because it depends on your present level of tolerance. If you told me you had no tolerance to stimulants, that you have not taken any stimulants in the form of a fat-burner in 3 or more months, then I would say start with just one PRO-XANTHINE cap in the morning, then as you start to build a tolerance, start taking a 2nd cap approx. 8hrs after the first cap, then as tolerance continues to build, up it to 2 caps first thing in the morning and 1 cap 8hrs later, I would not personally exceed 3 caps of PRO-XANTHINE per day! Hope this answers your question, that was the best I could do considering I wasn't 100% sure which product you were referring to when you said you were taking 3 caps a day.
