People can suggest nootropics all day long but you shouldn't fork out any money until you've done far more research.
Make a goal of what you want for yourself. Enhanced/heightened senses? Verbal fluidity? Better memory recall? Better information retention? Balanced mood? Motivation? Energy?
Why do you want to take Nootropics? School studies? Career improvement? Self improvement?
The best thing is to read articles on different nootropics. Observe conversations in this group. (be able to discern the meaningless comments and posts from the actually informative)
I'm being totally serious. My biggest mistake when I was new to this community was getting excited about things people were suggesting I take and buying a ton of stuff that did nothing for me. Or at least nothing I wanted it to do for me. I have quite a few things that I may never use. Of course, I highly researched them before I bought them (I don't put anything in my body unless I know everything about it there is to know) but I look back now and think "I was just really excited to try anything that I didn't think it through and bought everything." if I had to do it all over, there'd be quite a few things I would have never wasted my money on.
Also, keep in mind, just because it works for 1 person, doesn't mean it will work the same or at all for you. Everyone's body chemistry is different.
I'm not saying this to scare you away, just hopefully to help you make educated decisions on what step to take next. That's why I won't personally recommend anything to you. I've regretfully done it before and I wish I hadn't.
Nootropics are fun and you can learn a lot about them, just be smart about it and know yourself and your substances before you buy.
