Research notes
Research notes

Price is Amazon's current one-time price (sold by Amazon.com; no deal badge or Typical price shown on 2026-10-20). musclemilk.com was behind a bot check, so nutrition comes from the label image on the Amazon listing (copyright 2021, 'packaging may vary'). Its values match ShopRite and Kroger listings. One Amazon bullet says 32g protein, which conflicts with the label and the listing title (40g). Milk protein isolate and caseinates; 6g fiber.
