what's with 5 pounds now being 4.3

I guess MyProtein isn't going back to $50 anytime this year, maybe not this decade

Seconded. Difficult to find unflavored with a good price and quality.

No Sucralose, finally. It just uses Stevia, which comes from a plant, so it's solid. Price-wise, it's pretty good. Most 4lb-5lb bags are in the $70 to $80 range.

Pick one. Price or quality? Isopure probably has THE best non-flavored whey protein on the market but it's unfortunately pricey. You can get them at Sam's Club though.

Only vanilla is available at my warehouse at that 38.99 price. Not chocolate.

Thanks OP! Gonna order the chocolate to try. I normally buy Sports Research Vanilla when it's on sale, but wouldn't mind a different flavor (chocolate) to change it up. The Sports Research Vanilla uses stevia and is similarly priced when on sale, but the chocolate unfortunately contains sucralose.

Isopure most definitely does NOT have the BEST unflavored whey. Lots of better companies and products. And you can get 10lbs of isolate(best) or concentrate(still good) for $80-100 or better fairly often. I buy 30lbs at a time. Unflavored is the way to go since youre not paying for filler garbage. Just gotta read the label.

I used this before our Costco started carrying Levels. They are both about the same, Ascent maybe a bit better. Great product. I used it for years and will get some in warehouse when I go.

Seems that isopure is permanently gone at Costco. I tried this powder worried about my stomach but so far so good.

I highly recommend True Nutrition.

You can custom make a blend, or order their ready made products. Excellent quality and reasonable price.
