With the reindeers pulling him and thats a for life job, along with the amount of chimneys hes got to climb down, I'd say from the way it looks hes a Test E/Deca kind of guy. What he really needs to do is use Test C in hopes he doesn't carry as much water weight to boost productivity. Keep the Deca and he can add in some Anavar along with it. Santa needs 1 1/2 grams a week of Test C, 80 miligrams of Anavar a day, and about 400-600 miligrams of Deca a week to help keep his body comfortable with all that exercise hes doing giving presents.
