Is 99% or 98% enough or should I look for supplements with purity of 99.8-99.9%? My supplier probably sources them from China. I'm talking specifically about racetams but I am interested in other supplements too in case I will decide to purchase something else as well. They test in house by HPLC, although one of the supplements goes by "assay as dried base" and doesn't specify whether or not it's HPLC, UV or whatever (for noopept).
