You have put on 20 lb in three months.
That is pretty awesome.
Did you use performance enhancing substances to get up to 200 lb?
I have had this burning question about what is REALLY physiologically possible to do with muscle growth. I finally found an expert who did their PhD on skeletal muscle hypertrophy, and is a pro-nattie bodybuilder.
This is the response I got from him:
well typically the absolute max amount of amino acids that can be deposited in tissue per day is about 5-10g. So let's say you max that at 10g per day. 10X365 = 3,650 grams. 3650g/454grams per lb = 8.04 lbs. Now that is dry tissue weight. Skeletal mucle is only about 30% dry tissue and 70% water. so if 8.04 is divided by .3 you get about 26.8 lbs per year. Now obviously this is not set in stone but I think it's probably safe to say anything over 25-30 lbs of LEAN tissue gain per year would be close to impossible to achieve without anabolics.
There is only so far you can push your genetic and physiology, even with performance enhancing drugs.
Bodybuilding is a marathon, not a sprint.
