Mavy is correct. I use 10mg dbols as well, and for my size I take 30-40mg/day. One in the morning, two with lunch, and the last one 30min before my workout. I also run mine for about 5-6 weeks, but watch the ole liver. I always have mid and post cycle blood work drawn and so far I have had no problems. Even after 5 weeks of Halo.
