I'm not sure about prami, since I haven't had the financial wherewithal to try it yet, or about oxi, since I think it's terrible, but piracetam and especially aniracetam are highly compressible. If I had to guess, SmartPowders measured the
uncompressed powder.
I don't see why we should close this thread, seeing as there are potentially many other sources citing powder densities, and about which I have not had the good fortune to learn.
I'd also be interested to see how large the variance/std. dev. is between batches, to see how consistent the density is across all batches and all companies. There's not too much in the scholarly archives about racetam density, but it doesn't mean someone else can't locate other relevant info. I'd also be interested to see how compressible the powders are, and also how their compressibility varies across companies and batches.
But in my experience, if you find that you benefit from having consistent doses, it's better to invest in a $30 milligram scale than to rely on some scoopers.
