Our verdicts
EAA Powder
Nutricost EAA is cheap, tasty and better grounded than a pure BCAA drink because it includes all nine essential amino acids. The formula is so BCAA-heavy, with only token amounts of several essentials, that it falls short of the balanced profile research favors. It is fine as a low-cost training drink, but a scoop of protein powder delivers more complete amino acids for similar money.

Amino Complex
Amino Complex gets the science and the certification right: a balanced, leucine-forward essential amino acid profile with NSF Certified for Sport status. It is let down by a small dose, a high price and divisive taste. It makes most sense for tested athletes or people who can't use protein powder; everyone else will get more from a quality protein shake.
