I really like the layout of the Ultra if you are going more for lean mass gains or recomp and the enhanced if you are more for cutting. But like said you really can't go wrong with either one of those stacks. They are both incredible options
So spent the rest of my day going over the Mega ss and the Ultra ss...and watching Dylan's videos again. I'm going to go with the Ultra. I'm really anxious to see what s4 and s9009 do together!
