It is not a stim like clen or ephedrine, you won't feel edgy or heart racing.
No need for 2 on 2 off (even with clen its not needed if you also take Keto with the clen)
Id rec it ran for 5-8 weeks but nothing is set in stone for time. (go more or less if you want)
about 10mg ed seems to work well.
I would rec taking about 1g tribulus ed along with it, its good to take trib with it, it inhibits cox2 something something lol
Ofcourse diet still plays a BIG role int he fatloss.
good luck man!
