375lbs x 20 huh?
Your not to far off of Ryan Kennelly. He did 405lbs x 20 and he holds the world record along with repping 600lbs for reps raw.
He's also 60+lbs heavier than you. And you did this on only 500mgs of test compared to the grams and grams of aas he uses. Maybe if you get up to 290lbs you can break the world record while being on 500mgs?.........
