I am no expert, but I have NEVER touched an oral steroid, I've alway been way to scared of the side effects done to the liver. I'm 5'8" and weigh 175 very lean. I weighed 120 five years ago, adding about 10 pounds a year and I've never touched an oral 'roid. I've only used moderate injection cycles throughout the years and trained/ate like hell and I've gotten great results. The side effects of orals just aren't worth it, in my opinion.
