My best to date is the following. A few years back I was pretty amped up on a solid Test/Tren/Halo cycle. I mean I was coming into the gym feeling like I could eat 45 lb plates. I was hammering through a squat routine and really feeling like a beast. In all my excitement, I went to pull a 45 lb plate off one side and it felt so light I smacked myself right in the forehead with it. Left a golf ball sized welt on my forehead for a week.
