Unflavoured whey protein isolate isn't hugely popular but you can get it online.

edit - I should add, you can get a bit of an idea of the quality of the protein powder by just looking at the percentage of protein in it. Nutricost is 85% and Bulk Nutrients is 87%. Doesn't leave much room to shove other ingredients in with protein levels that high.

You can also go buy 20kg bags of WPI from NZ (which is where I think most of these retail products get their WPI from) https://www.nzmp.com/global/en/products/ingredients/types/pr...

What’s the price on those bags? I’m not contacting them and hidden pricing is scummy.

I think you have to bid on their auctions. It is more of a wholesale thing for people buying tons of it. https://pure-product.com/products/whey-protein-isolate-20kg-... they are reselling one for $709 USD
