FYI, several is more than 2. How many do you think several is? More than a few?
You will keep your weight if your pct and diet is right.
So you are 86kgs not 83. You are still 6'3 tall. Too light (189lbs) in my opinion although I guess you are gonna do this regardless. Do us the honour of posting a pic so we can see what we are working with, I'd like to see your idea of 'next to no bodyfat'.
