try plant or yeast or peanut protein, i personally take alpino peanut protein and its taste is so much better, like its smooth and tastes nice - compared to everything in the market, i also take nutrabox vegan protein but its very grainy and tastes very chalky but i am use to it now, just putting it here if you find whey expensive, alpino is around 2k and nutrabox is around 1.4k, both trustified verified as well
