Thread: Isolate VS Concentrate Whey

Which one is best for muscle growth, isolate whey or concentrate whey?

Which one is better for muscle growth, Provon whey or Mutant whey?

I also would like to ask what kind of supplement is best for muscle growth (I asked this question because there are a lot of kind of supplement and I am confuse and don't know which one I should buy and use for muscle growth)?

It doesn't really matter, it's just the process used to extract it from the milk - isolate is more expensive but purer. If you a) aren't bothered by lactose and b) have a slightly larger serving size then I would expect the results to be identical for concentrate.

I eat pea/quinoa protein powder. My gym tried to sell me that their protein powder was purer and mine likely was diluted with wheat or rice flour.

I wonder how one could test for the presence of flour.
