Optimum Nutrition Gold Standard 100% Whey - Chocolate Peanut Butter 2.27kg

What it is

Optimum Nutrition Gold Standard 100% Whey is the world's best-selling whey protein, made with whey protein isolate as its primary source. Each serving provides 24g of high-quality protein, 5.5g of naturally occurring BCAAs and 4g of glutamine to support muscle growth and recovery, while staying low in sugar and fat. It is banned-substance tested and mixes easily into water or milk in seconds. This 2.27kg tub in Chocolate Peanut Butter flavour provides about 71 servings.

Sweet, thick peanut-and-chocolate flavour that drinks best with cold milk and can feel heavy in plain water.

Who it's for

Regulars already training on Gold Standard who want a two-to-three month tub in a flavour with a bit more going on.

How to use it

Take one scoop after training or any time you need more protein.

Worth knowing

Contains milk. If you have never had a peanut butter protein, buy a 2lb of something first; this is a lot of tub to dislike.

Our take

2.27kg is the same tub size as our ON 5lb listings, just labelled in metric, which is worth knowing so you are not comparing two different things. About 71 servings of the isolate-led 24g formula. Chocolate Peanut Butter is heavier and sweeter than the plain chocolates, so be sure of it at this size.
