I haven't read the whole thread, but here is my "quick" opinion!
I believe if you are gaining weight, the less supps you need. its when you start losing you need to tweak here and there. and its very individual!
what should someone be "on" most of the time?
a pre workout (either company or home-made)
a post workout recovery (pro, creatine, etc)
an isolate, and a casien
and a great multi
everything else comes after all of those are in check IMO!
