Actually, i have run IP bol at 100mg/day as well as his winny at 100mg/day (not together). His shit IS underdosed, so more is needed, but it does work if you take enough. The only problem ive had when doing this was getting very tired all the time, but i got the same from ref-b.
Just my experience with IP gear......
BTW, had liver values checked not too long after 14 weeks of orals, no elevations.
