Our verdict
Impact Whey wins on transparency
On protein alone this is a dead heat: 67.6g vs 67g per 100g. Nothing to choose — which is exactly why the deciding factor is what the brands will show you.
MyProtein publishes a verified aminogram (leucine 7.26g/100g) and a verified ingredient list (Clean Score 90). Applied Nutrition publishes neither for Critical Whey — no aminogram, no verified ingredients in our data — so its amino quality is simply unknowable from the label.
Applied Nutrition makes excellent products elsewhere (their clear whey leads our clear-whey testing), but here the incumbent wins by showing its working.

Amino acids: why they matter
Applied Nutrition Critical Whey doesn't publish an aminogram, so amino quality can't be compared — we show verified data only, never estimates.
Who should buy which
Buy Critical Whey if…

Buy Impact Whey if…
You want verifiable quality — a published aminogram and verified ingredients — at the same protein content. Transparency is the tiebreaker.
Frequently asked
Which has more protein?
Effectively the same: 67.6g vs 67g per 100g. This rivalry is decided on transparency, not protein content.
Why does transparency matter?
Without a published aminogram, there's no way to verify leucine and EAA content — the numbers that determine how much of the protein can actually build muscle. We never estimate; we only show verified data.
