1. Bulk Pure Whey - my first choice Probably the closest straightforward replacement for Gold Standard. It's around 71g protein/100g and is generally cheaper; current comparisons put it at roughly 50p per 25g protein versus around 75p for Gold Standard, although prices fluctuate. proteindeals.co.uk
2. MyProtein Impact Whey - best if you buy during sales Very similar proposition to Gold Standard, with a huge flavour selection. It's particularly good when MyProtein runs a substantial discount; at full price the advantage is much smaller. www.wheywise.co.uk
3. Applied Nutrition Critical Whey - premium alternative Worth considering if you care about batch testing and sports certification. It's a little more expensive than the budget options but is a very credible alternative. proteindeals.co.uk
4. PhD Pharma Whey - best for a more premium shake Current UK comparisons rate it particularly highly against Gold Standard on protein effectiveness/value. www.theliftinglab.co.uk
5. Protein Works Whey 80 - good middle ground Another UK option that sits between cheap basic whey and premium products. Current comparisons put it ahead of Gold Standard on value. www.theliftinglab.co.uk
### My ranking
For most people: Bulk Pure Whey Cheapest: MyProtein Impact Whey when discounted Best premium alternative: PhD Pharma Whey Best if sports testing matters: Applied Nutrition Critical Whey Best overall if you don't mind paying extra: Optimum Nutrition Gold Standard
One important point: you don't need Optimum Nutrition specifically to build muscle. For a normal daily protein shake, the total protein you consume matters much more than the brand, assuming you're buying a legitimate whey product. Which? also found meaningful differences between popular protein powders, so it's worth looking at the actual formulation rather than just the brand name. proteindeals.co.ukwww.which.co.uk
If you tell me your budget (e.g. £30/£50), preferred bag size, and whether you want whey concentrate/isolate, I can find the 5 cheapest current UK options per 25g of protein.
