I have used prohormones in the past here are some that seem to work well for most people. Tren Xtreme, TT-40,and Methyl Masterdrol. On the Tren Xtreme at 5'8" tall I went from 235 to 250, then I stacked TT-40 with Methyl Masterdrol and I went from 250 to 265. I wasn't trying to get bigger either I was just trying to get stronger. I was also using Hypershock by Myogenix and L-gutamine. Most of my protein was coming from meat. Steaks, pork roast, whole eggs and cottage cheese. You get the picture. I also hit the biggest lifts of my lifting career and I am 42 years old.
