Does Piracet actually work?

So, I’ve been running into some real issues with my concentration when I try to study. Don't get me wrong—the motivation is there—but actually staying locked into a book? That’s where things fall apart. Up until now, I’ve experimented with various "supplements" like lecithin, which turned out to be overpriced junk that didn't do much of anything. After doing a bit of digging online, though, I stumbled upon Piracetam.

I’m curious: does this stuff actually help with focus? Is it worth ordering, or am I just looking at another waste of money?
