Frequently asked questions

What's the protein source in Gold Standard 100% Whey?

Whey protein isolate is the main source. It is blended with whey concentrate and whey peptides. The exact protein per serving depends on the flavour and pack. Check the label of the tub you buy.

Which UK shops stock Gold Standard 100% Whey?

We list it direct from Optimum Nutrition. We also list it at Amazon UK and at Holland & Barrett. Each shop may stock a different pack size. Compare the price per kilo, not the headline figure.

Is it certified for banned substances?

Yes. It carries Informed Choice. It is tested by LGC's anti-doping lab. It is checked against the WADA banned list. Optimum Nutrition lists its certified batches on the Informed Choice database.

How many flavours does it come in?

Gold Standard 100% Whey comes in a wide flavour range. It is far more than most protein powders. Which flavours are in stock varies by retailer and pack size.

What's the difference between Gold Standard Whey and Gold Standard Isolate?

Both are Informed Choice certified ON products. The standard 'Whey' is an isolate-primary blend with concentrate. The separate 'Isolate' line is whey protein isolate only. It comes in a narrower flavour range.
