Nah, you don't really wanna be taking soy protein. Considering guys who train are supposed to consume protein in large quantities, you'd probably end up taking in quite a lot of soy protein in your shakes..And soy ain't really very good for guys
It's fine for girls, though, although soy ain't the best quality of protein anyway..

Not the case. This used to be debated about phytoestrogens and blah blah, and was tossed around 5 years ago, and there is no more debate over soy, and never should have been.
Soy protein contains all the EAA
Soy has 4x the amount of Arginine as whey and 2x of casein.
Roughly 7.6g per 100g serv and not to mention about 10.5g of glutamine per 100g serv.
Studies prove it does just as well as a job as Whey, and the levels of test and estrogen aren't even a worry.
Now should you TOTALLY use it? NO, that's why you use the mixture. There are also antioxidants in Soy as well.
I personally use a blend. I just got done using 1/2 scoop of a 5 blend protein along with 1 scoop of CFM Whey Isolate.
I've used a small percent of soy isolate for years and never had a problem.
So your mis-informed on the quality of it, and what it has to offer. Sure most your kids and people who know nothing about this industry will tell you otherwise or make a fuss, but these are the ones who haven't researched anything, and their lack of knowledge only hurts them.
Ask how many people know about the Glut/Arg I spoke about and I would say a VERY small percent. That's because so and so's friend says take ONLY whey, soy is really bad, so on and so on, and they dont bother to dig deep in the research. I see it all the time.
BTW... Soy digests almost as quickly as whey.

Evansville, IN (AHN) - A new study has debunked a commonly held myth that soy protein isn't as good at helping men build muscle as whey protein is. Researchers at Indiana University's School of Medicine found that soy protein works just as well as whey protein in promoting muscle protein synthesis.
So men who have avoided eating soy protein, while they try to build muscle can start enjoying it - along with enjoying soy's health benefits of helping to lower cholesterol levels and helping avoid developing certain cancers, researchers said in a statement Thursday.
Researchers used rats in their study. They divided the rats into groups that were fed a carbohydrate only meal or a meal that combined either soy protein or whey protein with carbohydrates. They then put the rats on a treadmill for 120 minutes and tested them afterward.
They found that found soy and whey proteins were equally effective at promoting general protein synthesis in the rats' skeletal muscle.
"Taken in total, our study suggests both soy and whey proteins are useful sources of protein for muscle support following aerobic exercise," the researchers wrote.
