Are you referring to "halotestin?" If so, I wouldn't go above 30mg/day split between 2 doses. I used it pre-contest with great results. It seemed to harden me up, increase vascularity, and kept my strength up while dieting. This is harsh on the liver, so I'd only stay on 4 weeks maximum...maybe only 5 days on 2 off, as well. Watch out for headaches.....sign of high blood pressure. Visibly, I don't think you'll have great results unless your b/f is extremely low (ie, under 6%). Just my thoughts.
