XXL Nutrition vs Myprotein: Which One is Cheaper?

Two giants in the European supplement market: XXL Nutrition (Dutch, own production) and Myprotein (UK, largest online brand worldwide). Both claim competitive prices. But which one is actually cheaper when you look at price per gram of protein?

Spoiler: the answer depends on when you buy and which product you pick.

The Products We Are Comparing

We are looking at the best-selling whey from both brands:

• XXL Nutrition Whey Delicious — their flagship concentrate
• Myprotein Impact Whey — a bestseller for 20+ years

Both are whey concentrate, similar protein content (~75-78%), and available in large bags.

Price Per Kilo (Retail Price)

At retail price, XXL wins by €4 per kilo. But wait — Myprotein constantly runs discount promotions.

The Reality: Myprotein With Discount

Myprotein almost always has 30-50% off. Impact Whey 2.5kg regularly goes for €39-45. Then the picture changes:

With discount, Myprotein is €6.40 per kilo cheaper — that is significant.

When to Choose XXL Nutrition

• Fast delivery — warehouse in NL, often next-day delivery
• No hassle with discount codes — price is price
• Dutch customer service — easier communication
• Physical stores — you can visit if you want

When to Choose Myprotein

• Maximum savings — with discounts often 20-30% cheaper
• Huge flavor variety — 40+ flavors
• Clear Whey and specials — more product innovation
• Bulk buying — 5kg bags even more affordable

Protein Content and Quality

Both score similarly:

• XXL Whey Delicious: ~23g protein per 30g serving (77%)
• Myprotein Impact Whey: ~21g protein per 25g serving (84%)

Note: serving sizes differ. Per 100g powder, Myprotein sits slightly higher in protein percentage. In practice, you barely notice the difference.

The Verdict

At retail price: XXL Nutrition wins by ~€4/kg.

With discount: Myprotein wins, often by €5-8/kg.

My advice: always check current prices. Buying Myprotein without a discount is a waste — wait for a sale or use a code. XXL is reliable if you do not feel like discount hunting.
