Would like answer to this one as well.
I tried few protein powders and mostly got diarrhea. Read somewhere our gut can't absorb more than 15g of proteins at once and most scoops have around 20g of proteins.
Reading now about Trutein and PES Select Protein and can't really decide which one is better since very similar profile. And then there are Quest bars that also looks good. Just can't keep track of all these products hitting the market.
