Maybe Study Stack

Hello all,
Well it's been a while since I posted. I been busy with life and work. Well I got off my big stack where i was taking about 5 to 6 different nootropics. I been off for about 2 months now. I just recent started taking piracetam once again to see if it did anything for me. Just like before it did nothing for me. I stayed on it for about 1 month here and there missing 1 /2 days during the week.

I'm decided that I need to move on and try aniracetam once again. I have always loved this nootropic plus oxiracetam.
Well i started about a week ago on aniracetam, so far so good but i got inpatient and stack it with noopept. Now my question what do you guys think about this stack.

Now is that a good dosage to start with on noopept or aniracetam?

I'm back on studying for and exam in about 2 months that I need to pass for work. Please let me know what you guys think any feedback would be awesome.

Thanks,
