'Which whey should I choose?' It's THE question when you want to speed up muscle gain. Concentrate or isolate, dosage, price per kilo, taste… the choice can quickly become a headache. Here is our 2026 comparison to pick the right protein, with confidence.
How to choose your whey protein
- Protein content: aim for 20 to 25 g per serving (at least 70% protein in the product)
- Type: concentrate (best value) or isolate (purer, low in lactose)
- Price per kilo: compare the real cost, not the bag price
- Taste and mixability: crucial to drink it every day without forcing it
- Brand and transparency: labels, quality testing, verified reviews

Concentrate or isolate?
For most lifters, whey concentrate is more than enough: same amount of protein, lower price. Isolate only really matters if you're lactose intolerant or in a very strict cut. Don't pay more for a benefit you won't use.
Should you add creatine?
Yes — it's the most studied and most effective supplement for strength and muscle gain. 3 to 5 g of creatine monohydrate per day, every day (timing doesn't matter). Paired with a quality whey and progressive training, it's the winning duo.

The #1 proven supplement: 3-5 g/day for more strength and size.
Mistakes to avoid
- Choosing only on the bag price (look at price per kilo and protein content)
- Rushing to isolate without needing it
- Ignoring taste: an undrinkable whey ends up in the cupboard
- Believing whey replaces real meals: it's a supplement, not a substitute
In short: a good whey concentrate, 20-25 g of protein per serving, a taste you enjoy, plus creatine — that's all you need to support your muscle gain. The rest is training and consistency.
