I would point out, the first 4 weeks of osta where good, the next 4 weeks only gave problems, bloat, lower erection quality etc... . If I use it again, I`d stick to 4 weeks. After over a month of using brawn atd (same as old erase) started with 25x4 daily, tapered down to 3, 2,1. I alos addded 250mg x 2 of L dopa(98%) daily... and that definitly took care of prolactin issues in a few days, actually after just taking 1, I felt it...down there ;-) Also, after getting estrogen and prolactin down, I get harder and more vascular than on a cycle, so for me, it seems getting those to hormones in check, does wonders. Training eod, instead of 5-7 days a week, put my total test levels in the top range, and free test at near max levels, so I kinda think I have been overtraining for 10 years! Trying X factor now, finally availbe where I live, doing 3-4 caps a day. Expensive though for high dosages...
