Outcomes
What synapsa actually does, by outcome
Each row is one outcome with effect size, evidence base, the dose that worked in trials, and time to first effect. Magnitude tiers come from native-unit MCID where available, Cohen's d otherwise.
Shortens the gap between seeing a question and having the answer.
Names, conversations, faces, and details stick instead of dissolving.
Concentrate longer, resist distraction, and stay mentally sharp through demanding tasks.
Broad gains in memory, speed, and mental sharpness at once.
Organize priorities, switch tasks, and catch mistakes more easily.
