Legion Whey+ Review

A true whey isolate at 22 g per serving, Labdoor-tested, with no artificial sweeteners. What you actually get for the price, and when a cheaper concentrate is the smarter buy.

Updated 2026-08-29Independent review
The verdict

A genuine isolate with third-party testing and a clean label. You are paying roughly double the price of a mass-market concentrate for those three things, and nothing else.

What you are actually buying

Whey isolate is whey concentrate that has been filtered further. The filtering strips most of the lactose and fat, which raises the protein percentage and makes it easier on people who do not tolerate dairy well. That is the entire difference, and it is a real one — but it is a difference in purity and digestibility, not in how much muscle you build.

Does isolate build more muscle than concentrate?

No. When total daily protein is matched, the trials do not show an advantage for isolate over concentrate for hypertrophy or strength. If you tolerate dairy and you are hitting your protein target, a concentrate does the same job for less money. Legion sells one of those too, and it is the cheaper honest answer for most lifters.

Where the price actually goes

Three places. The isolate itself costs more to produce. Labdoor testing is paid for by the brand and most companies skip it. And the sweetener is stevia rather than sucralose, which is a preference rather than a health finding — the safety case against sucralose at normal intakes is weak.

Who it is for

Buy it if
  • You are lactose-sensitive and concentrate bothers you
  • You want third-party testing and are willing to pay for it
  • You want a label with no artificial sweeteners, flavours or dyes
Skip it if
  • You are on a tight budget and tolerate dairy fine — buy a concentrate
  • You are not yet hitting your daily protein target from food. A powder does not fix that
  • You expect the powder itself to build muscle. It is food, not a stimulus

Questions

How much protein do I actually need?
Roughly 1.6 to 2.2 g per kg of bodyweight per day for someone training for muscle. Total daily intake matters far more than the timing of any single shake.
Is 22 g per serving enough?
For one serving, yes — the muscle protein synthesis response tends to plateau somewhere around 20 to 40 g of high-quality protein for most people. Two servings do not double it.
Does whey cause kidney damage?
Not in people with healthy kidneys. That claim comes from advice given to patients who already have kidney disease, and it does not transfer to healthy adults.
