visitnigPlatinumisopure is straight up protein, no carb/sugar fillers.But its also only 2.5lbs and costs $45. I can get same amount from optimum nutrition for the same price. Tbh I would rather just spent the money saved from buying a cheaper protein on creatine which probably helps just as much when it comes to working out
whey protein isolates are generally much more expensive than general blends like ON's gold standard. it's refined and just simply protein.
