I have been on 4ius a day split into 2 in the AM and 2 in the PM for nearly 6 months now and love it, more for the leanness/hardness aspect though.
I do not see a tremendous amount of growth from it as some have, but I swear it has aided in reducing test induced bloat in me, I have stayed lean and hard all the way through on Sus Eod for the last 12 weeks + EQ @ 600 pw and Deca @200 pw (joints!!)
I love the stuff, I do straight 7 days on though also, no 5 on 2 off..
