Legion Plant+ Review
Pea and brown rice at 24 g a serving. Plant protein needs a bigger dose than whey to do the same job, and this page shows the arithmetic.
A clean pea-and-rice blend at 24 g a serving with no proprietary blend. It costs $2.50 a serving, more than most whey, and plant protein needs a larger dose than whey to trigger the same muscle response. Buy it because you do not eat dairy, not because you think it is better.

Why pea and rice are blended and not sold alone
Pea protein is low in methionine; rice protein is low in lysine. Each one covers the other's gap, which is why serious plant powders blend them rather than sell a single source. The ratio here is roughly 73% pea to 27% rice, and the combination gives an amino acid profile close enough to complete that the distinction stops mattering at normal intakes.
The leucine gap, and what it costs you
Leucine is the amino acid that switches on muscle protein synthesis, and the threshold is somewhere around 2.5 to 3 g in a serving. Whey carries roughly 2.5 g of leucine in 25 g of protein. Plant sources carry less per gram, which is why the research that finds plant protein equivalent to whey generally does so at higher doses. In practice: if you are using this to build muscle, treat 30 to 40 g as your serving rather than 24.
What you are paying
At $49.99 for 20 servings this is $2.50 a serving, which is more than Legion's own whey isolate at $2.17 and considerably more than a mass-market whey. Plant protein is more expensive to produce and that is reflected honestly here rather than hidden. If dairy is not a problem for you, whey is the cheaper and slightly more efficient option and we would say so.
Who it is for
- You are vegan or avoid dairy
- Whey has consistently upset your stomach
- You want the sources and doses printed
- You tolerate whey and are choosing on price
- You want the smallest scoop for the protein
- You expect it to outperform whey — it does not
