you could technically use it for both. i went through one bottle with the 5on/2off protocol and yielded excellent results, increase in strength/indurance, and a little drop in bf% (during my first bottle i stacked this with incranate and anabolic edge as well so i cant say it contributed 100%). i have three bottles left and im going to experiment a little and do 9 ed stacked with incarnate and it's going good so far! keep in mind tho this isnt the "muscle pill" it's marketed to be, you need to bust your ass everyday and have your diet striaght, then you will notice great results! any questions just ask!
