I took 2 to 3 tabs per day for about a year. No mass gains, but strength was through the roof! No liver problems either (had blood work every 3 months). Not my favorite oral though. i lied to my physician some time ago, told him I was impotent, it was just prior to Viagra, so at that time they prescribed Halotestin. I took them every day for about 5$ for a months supply....prescription insurance covered them!
