i tried the 1 week cycles, since im one that gains most the first week.i did 1 on, 1 off, 3 cycles. 6 weeks total. with me it seemed like my body just took it as a 6 wk. cycle at a very low dose. i didn't make gains while on and stop while off, the gains weren't very much but they continued through the whole cycle, on or off. i gained a few lbs. didn't get noticibly bigger, but my strength went up a lot. i used 20mg. this was just an experiment with me but i considered it a failure.
