Protein powders

[Scaffo]

Hi, anyone know of any 90% protein powders on the market? Back in the day Balance (under Nutralife) did a 5kg tub of WPI unflavoured at 91 grams per 100 but it looks like most of them are around now are 75% and buffered out with maltodexrin. I’ve been adding skim milk powder to Calcitrim milk to take the 5.8 grams per 100mls up to 8grams per 100mls but caeseinates aren’t as easily metabolised as WPI of WPC. Any suggestions on brands/products would be appreciated.
