I wanna get some whey isolate, 90% minimum protein content, and i cannot find anywhere, in store that sells it cheaply. I was going to try getting it in holland and barrett, but its like £25 for 908g, which is so expensive. ive seen on amazon and ebay that you can get 20lb of the stuff for about £65, which works out about £6.50 for 908g. any ideas where i can get some cheap!?!? btw i cant get it online. in store only!
