Oh, its possible, but the effects and $$$ would be quite large.
I would say if he is in teh 220 lbs range it would take something like the following stack to maintain his lbm (and a near starvation diet)
Test prop 150 mg a day
tren 150 mg a day
winstrol 100 mg a day
letro 1.25 mg ed
t3 150 mcg a day
clen 100-150 mcg a day
hgh 4-6 iu's a day
He would be pretty shut down, and would rebound afterwards, not to mention feel half dead from teh 2000 calorie diet, but it could be done. Its just a stup idea.
