Scoop
Gold Standard 100% Whey tubs (UK & EU) now contain a clear plastic scoop. There is no branding on this.
*This is a recent changeover from prior use of gold scoops. You may still find these gold scoops in your tubs in the short term.
Tub design
Gold Standard 100% Whey Tubs (UK and EU) have a circular indentation on the bottom. There is also a line running through the middle.
Vacuum seal
Optimum Nutrition protein tubs have a cardboard vacuum barrier that helps hold powder in place during shipping. This gloss white protective disk should be stuck to top of the tub. Check that seal has not been tampered with.
