I've done m1t like this: Two weeks on/Two weeks off... because i heard of the crazy shutdown style sides of this "steroid" I only took 5mgs ed while on. While off, i ran 10mgs of Nolvadex. I did this for about three times through. Didn't see ANY sides, but had some nice gaines. (about 5-6lbs of good hard muscle). At the time, this is all i wanted to add, so I was happy with it. HOpe this info helps
