whats the verdict on this noot? some people have definitely tried it on here

from what i've read, not a lot of info, some good some bad. can anons say if this is accurate? do the memory effects also last after usage, or only when on it?

>only take 10 mg a day, for 2-3 days in a row, never use daily
>by far the best memory enhancer, especially for exam studying/performance
>capsule is best, the powder is caustic and gives people cavities
>some reported side effects from daily use include anxiety
>possible an HDAC inhibitor, but mechanism of action isn't truly known
