What are the risks and benefits of phenylpiracetam?

I’ve never been much interested in nootropics. I did try piracetam years ago and didn’t see any effect. But I was doing some research on AMPA agonists and it seems that there are precious few available outside of a lab and this happens to be one of them.

I can hit google of course and have already done some cursory research and will be trying it for myself - cautiously of course - but I’m interested in any information or experiences that others might have to share.
