I would think that 6 pumps a day should be pretty ample it really depends on what you are trying to get out of it. SImpla AI and test boosting properties you are in the top end of the money range right now. More conversion into the androgen 4-hydroxytestosterone to see more intense muscle hardening and what not then 8 pumps seems to be where that starts getting good. Keep in mind there is a difference and different schoold of thought regarding taking enough for a decent amount of conversion to 4-hydroxytestosterone since if use in PCT at these levels it could actually inhibit your HPTA however the many say the doses needed for this are pretty high. I would like to think that the SERM properties of Resceratrol should keep that from being any problem at all though, but it is important to mention if your goal is to go that route. We are talking about 200+ mg of formestane a day here before that would even be a consideration.
