Worse than cheque drops or halo on the liver. 100mg/day of anadrol AND dbol and my liver values were still in normal range. 3 weeks on Mdrol at 2 or 3 caps/day, and alt was 190, ast 160. After I stopped it, 3 weeks later they were back to normal. I'll never use those fake-ass crappy prohormones again... real gear always works better for me and is always cheaper!
