2 YEAR 105lbs - 210lbs NATTY OR NOT?

This online associate of mine is a complete sociopathic liar. Says it has just been 2 years this September since he started lifting. Dude is 6'2 went from 115lbs to 200+lbs within that timeframe. Says it was natural but his lats and shoulders dominate his physique. What do you guys think?
