Solid mid-range option. Prozis runs aggressive promotions — wait for a sale and you'll get excellent value, especially in Spain, Portugal, and Italy.

The most trusted whey in the world. You're paying a premium for the brand and consistency. Great if you want zero risk — but objectively not the best value.

✓ Pros

Good option if you want unflavoured whey or live outside standard European shipping zones. Not the best protein % but clean ingredients.

✓ Pros
- • Popular in Eastern Europe

A popular choice in Eastern European markets. Decent option but lacks the transparency of Bulk or the value of Myprotein.
Check Price →How to Choose Whey Protein
Protein % per serving: Look for 75%+ protein by weight. Anything lower usually has more fillers, sugars, or fat padding out the serving size.
Concentrate vs Isolate: Concentrate (WPC) is cheaper and contains slightly more fat/lactose. Isolate (WPI) is purer (90%+ protein) and better for lactose intolerance — but 30–50% more expensive. For most people, WPC is fine.
Price per serving not price per kg: Always compare cost-per-30g serving, not the headline kilo price. Serving sizes vary wildly (25g to 40g).
Third-party testing: If you compete in tested sports, look for Informed Sport or NSF Certified badges. For recreational lifters, it's less critical.
