I'm 100% all nachural. I usually do 5 days in a row but I've been trying to move it to 4. I hate lifting on Saturdays so I usually bang it out Mon-Fri or Sun-Thurs although I usually eat like shit on Saturdays so Sundays don't go too well.
I've been eating very, very strict at least 5 days a week since I cut in this summer but I'm definitely starting to feel the 5 days. Really tired in the morning and starting to plateau. Need to eat more carbs but I'm a paranoid pussy now. 
Today:
Squats
SLDL
Leg Press
One leg extensions
Lying Leg curls
Calves
Abs
