[Need rec] for unflavored protein supplement

Hi all,

Recently started tracking macros more seriously, and found out (to no surprise) I need to boost my protein intake to reach my goals.

I've just been using up some old protein powder from before, but am starting to run out and thought it might be a good time to find one that I can enjoy a bit more. So the cheaper ones and more readily available options off the shelf seem to always come in flavored packages (usually vanilla/choco/peanut butter)

While cost is still a consideration, I'd like to have one that is not artificially flavoured/sweetened since I mix my own smoothie with fruits and the like. I know that it'll probably have some whey taste or whatever, but that's acceptable (I know it's hard for anything to be completely unflavored, and probably unappealing anyways)

I have no dietary restrictions, so I'm open to any and all suggestions, and don't mind if the suggestion is vegan or whatever either. I'm located in the Canadian PNW, and would appreciate if it's something I can just grab off the shelf from a store, but I don't mind buying online either as long as shipping isn't exorbitant.

Anyhoo, thanks in advance everyone!
