Alpha Brain verdict

Alpha Brain uses proprietary "Focus" and "Flow" blends that legally hide each ingredient's dose. The amounts we can see fall below clinical thresholds, and the hidden ones can't be verified at all. You're paying $1.95/serving for underdosed nootropics — the same ingredients run about $0.48/serving in bulk.

Nootropic Stack verdict

Refreshingly transparent — every dose is disclosed, there are no proprietary blends, and the rhodiola is right on its studied dose. The catch is the two headline aminos run light: 500mg tyrosine and 100mg theanine are each about half their common reference doses, so it reads more like a gentle daily stack than a heavy-hitter. At ~$1.67/serving you're paying a real premium over the ~$0.30 it costs to build the same four actives in bulk.
