Protein Recipes

Apparently there is a website that shows you how to create your own protein powders(by this I mean the correct ratios of whey, creatine, dextrose etc., etc.) Has anyone come across this site? I’m going to buy my powders in bulk from bulkpowders.co.uk, so I’d like to have the breakdown of the recipes in front of me so I know what, and how much, to buy.

Thanks,

Tone
