Quality of buying bulk vs buying big brand names.

This might be a silly question but I'm new. So I'm just wondering is there big difference in quality when buying from a cheap bulk supplyer compared to a big name brand such as ON, muscle tech and so on?. Ino it deppends on what each product contains. But let's just say a standard whey protien from a cheap supplier compared to a top brand one?.

Cheers for the help.

Any help?

Well, there's no such thing as "standard" whey protein. What exactly are you looking at buying?

Whey Protein Concentrate 82% Instantised from bulk powders

Here is the site. http://www.bulkpowders.co.uk/product...__instantised_

sorry if your not allowed to post other sites.

Concentrate has a lot of junk in it. You're gonna want isolates, either micro-filtered or ion-exchange

They have a Whey Protein Isolate 90% so that sounds good. Thanks fir your help nooomoto
