anybody use soy protein isolate?

[Hercules]

been thinking about adding it to a mix after lately hearing a lot about all its added benefits, very economical, and how its supposedly not so low grade anymore due to today's high tech procedures. i know markus ruhl uses it along with egg white for his shakes. supposedly good for pre contest when many people cut out whey products. anyone here use any soy products with good results? thanks

It contains photoestrogens and Id figure that would make it suck for precontest. Thats why its a very popular protein for women. The PER sucks too, you say thats changed, I dont know...
Im sure a whey isolate would be better.

Soy is shit.
And why would you cut whey isolate before a comp? People only do that because the so called pure whey isolates they get are full if fillers and don't meet label claims. But if you have a genuine pure whey isolate, you can use it until you walk on stage - it has no lactose, no carbs, no fat, just highest grade protein - why would you cut that out?

i wouldn't cut isolate, i was just saying cause i've talked to numerous people who cut shakes out all together before a contest, but my guess is because theirs contained lower grade stuff such as concentrate? i wouldn't know cause i've only used isolate and have always used it up till contest.
