Some before/after shots.
First pic(170 lbs) was after loosing about 50 lbs on a low carb diet
Second pic(205 lbs) was after a 1-t/4ad 5 weeker
Third pic(228lbs) was after a 20md/day 3 weeker of SD
Can anyone estimate my bodyfat in the third pic?

I would put you anywhere from 18% - the low 20's.
Hard to tell with that pic.
Yeah, I'm guessing 20, but hard to tell.
18'ish could be lower, seems like your stomach is your problem area
are you bulking?
