At one time I thought 50 mgs ED(halo) was bold.But as usual I change my mind/views on things like this and the desire to experiment runs arage with-in myself
I still think you don't need to run over 200 mgs ED of drol.Not that it's physically impossible,but isn't any more effective.Reason I say that is,right before my decission to switch to Halo in my current cycle.I was running 250 mg Ed drol.Wasn't all that impressed,so I decided to venture into a real mans drug(halo).
Never ran Halo in back to back cycles to determine whether it will/won't be less effective.So I can't comment on that.But as you know,running drol/dbol/winny or similar in back to back cycles is totally a waste of time,and drugs.
