In all honesty, you're better off not using stims of any kind. Any fat you lose from it will come back. I got down to 6% bp without a single fat burner.
I've been working on a non stim fat burner for years. Maybe one day I'll get the combo of ingredients good enough to release it. But it will not be one pill. It would have to be different pills taken at different times and most guys wouldn;t go for that.
