Why this certification matters
- NSF Certified for Sport
- NSF Certified for Sport is designed for athletes in tested sports; each lot is tested for substances banned by major sports organisations.
Frequently asked questions
- Is this the same as regular Gold Standard Whey?
- It's the Double Rich Chocolate flavour of Gold Standard 100% Whey, in the NSF Certified for Sport version. The whey blend (isolate-primary, ~24 g protein) is the same; the NSF certification is the distinguishing feature.
- Why do the UK prices range from £25 to £70?
- Different pack sizes and retailers — £25 at Boots, £40 from ON direct, £61 at Amazon UK and £70 at Holland & Barrett. Compare price per kilo rather than the headline figure; larger tubs cost more outright.
- What does NSF Certified for Sport mean here?
- Every batch is screened against 280+ substances on the WADA banned list — the tier used across US professional leagues. It's a stricter, batch-level certification than the Informed Choice on some other ON lines.
- How do I mix it?
- Optimum Nutrition suggests one rounded scoop in 180–240 ml of cold water or milk. It also works stirred into porridge or a smoothie.
- Where's it cheapest in the UK?
- Boots at £25 is the lowest of the listings we track, ahead of ON direct (£40). Check the tub size, as the cheaper listings may be smaller packs.
