As you said, you need to look at individual resellers/distributors and see what kind of QC/testing is being done on a company by company basis. Raw ingredients are sourced from China regardless of if they're expensive "designer" supplements or cheap generics. My comment was more along the lines of different formulations don't seem to have any difference wise, meaning that you can buy high quality generic creatine monohydrate at fraction of the price of something like Creapure(which is just monohydrate), creatine HCL, ethyl ester etc. Again, you need to audit who you're getting your supplements from - cheap doesnt always = poor quality and expensive doesn't always = high quality
