For the mathematically challenged, 155 pounds would be less than a pound over the limit for lightweight, and would cause you to have to compete as a middleweight.
I competed in 3 tested NPC shows in 1994 and 1995, as a light-heavyweight each time.
Squad, I said it "could" happen in the next 10-15 years. not that it "would." If I don't need HRT, I won't bother.
