the original dosage was 2 caps 3 x's a day. it was changed about a year ago(not sure of exactly when). I take 2 caps 3x's daily. i switch with clen every 2 weeks. works great! Just make sure you use RFA-1, EFX sux(no eph.) and don't take your last 2 caps too late in the day, unless u don't like to sleep, LOL.
