phenylpiracetam for improved brain function

In studies, 400 milligrams of phenylpiracetam taken daily for a year significantly improved brain function and cognition in people recovering from a stroke;1 200 milligrams of phenylpiracetam taken for thirty days improved neurological function by 7 percent in people with brain damage2 and by 12 percent in people with epilepsy.3 In studies on rats, aniracitam improved memory and countered depression.4 A single small study of piracetam in healthy adults found that after fourteen days it significantly improved verbal learning.5
