Quick answer
Bulk Pure Whey is the best direct MyProtein alternative. It competes on the same everyday-whey job with simpler pricing. THE PROTEIN WORKS Whey 80 is our second alternative; Applied Nutrition Critical Whey is the tested-sport upgrade; Gold Standard is the taste-first premium swap. We would stay with MyProtein whenever its delivered cost per 1g protein is within 10% of Bulk because its flavour and pack range is stronger. Switch to Bulk when the saving is larger or when code-driven pricing has become more effort than it is worth.
1. Bulk: best budget alternative
Best suited to anyone whose main priority is paying as little as possible per gram of protein. If you buy Myprotein Impact Whey because it is cheap, Bulk should be your first comparison. Both deliver a strong amino acid profile suitable for post workout recovery, so the switch is straightforward.
- 1
Bulk Pure Whey Protein consistently sits within a few pence of Myprotein Impact Whey on cost per 100g, and sometimes beats it outright.
- 2
Pricing is more transparent, with less reliance on inflated RRPs and permanent "sales."
- 3
Many buyers find Bulk's vanilla and chocolate flavours taste more natural than Myprotein's equivalents.
- 4
A solid range of bag sizes from 500g to 5kg, plus regular bundle deals.

Community perspective
What others are saying
bulk.com maybe? They're a bit more expensive than old myprotein, but a fair bit cheaper now. Also quality is pretty decent. Else I'd check on Amazon for some cheap brands.

Have many sales on? MyProtein seems to send me 3 a week.

Do you use their apps or do you get the notification through emails? Have you bought anything recently from myprotein? If yes, how much did you pay in total for the items?

4. Protein Works: best for flavour variety
Best suited to anyone bored of the usual chocolate, vanilla, and strawberry rotation who wants to experiment. Also a good pick for diet-focused or meal-replacement blends.
- 1
Genuinely creative flavours such as Choc Peanut Cookie, Banoffee, and Millionaire's Shortbread, which tend to taste good rather than just sound interesting.

Best suited to people who want to pick up protein powder during a weekly supermarket shop, without ordering online or waiting for delivery.
- 1
PhD Diet Whey is stocked in Tesco, Asda, Sainsbury's, and most major UK supermarkets, a retail presence no other brand on this list matches.

Formulated as a diet protein, with lower calories and added CLA, L-carnitine, and green tea extract.
- 3
No shipping costs, no minimum orders, no waiting, just take it off the shelf.
- 4
Supermarket loyalty points such as Tesco Clubcard or Nectar apply, a small but real saving.
When Myprotein still wins
Myprotein is not the default for no reason. Here is when it remains the right call.
- 1
Deepest sale prices: during major events like Black Friday or payday sales, Impact Whey can drop below every alternative on this list.
- 2
Biggest flavour range: nobody comes close on variety, with 40+ flavours of Impact Whey alone.
- 3
Bundled accessories: shakers, bars, and clothing make Myprotein the widest one-stop-shop catalogue.
- 4
Isolate pricing: Myprotein Impact Whey Isolate remains one of the cheapest isolates in the UK.
How to choose
None of this means Myprotein is bad. It simply is not the only option, and depending on what matters most to you, whether that is convenience, taste, transparency, or in-store availability, one of the alternatives above might suit you better.
Ask yourself one question: what annoys you most about your current protein powder? Or skip the guesswork and compare all of them on price using the live comparison table, which shows what everything actually costs right now. Whichever brand you pick, look for a protein shake that fits your budget, mixes well, and gives you enough protein per serving to support recovery. All five alternatives above meet reasonable quality standards for the UK market, so the real choice is about price, taste, and convenience rather than any meaningful gap in nutrition.

Price? Try Bulk for comparable quality with more honest pricing.
- 2
Hassle? Try Applied Nutrition on Amazon for next-day delivery with no codes needed.
- 3
