Have you ever think about the purity of bulk powder we purchase?
I have no clue to tell. Also, seems there isn't any well-established drug makers for some nootropics like Pramiracetam. Do you have any idea how to check the substance that we purchase?

I'm surprised nobody replied. Of course, with compounds that are to be consumed in gram quantities, even 5% impurities, which is not uncommon for generic chemicals, can be a hazardous thing. The only really effective way to check allegedly pure bulk powders is to find someone with a GC/MS machine. Testing for a single substance can be inexpensive.

A simple test that's surprisingly effective is to test melting point against reference data, if the substance isn't one that decomposes without melting, and make sure there's a sharp melting temp. For instance Piracetam's is 152 degrees C. All it takes is some capillary tubes, a lab thermometer, and some mineral oil. For herbal preparations, it's pretty hopeless without a complete lab.
