Most plants have so little methionine. Even if your beens have 50g of protein, half of it can't be made into muscle because the methionine is the limiting factor. No problem with meat, though. Just beaf is low in tryptophan. Fish have the most methionine. It's bull sh*t if you ask me.
Methionine is the most expensive L amino acid powder. I'm not sure how well it is absorbed, though.
