Do you have good place to get piractem? I've been looking around and it seems like all the amazon product links have been removed lately.
Amazon is no longer allowed to sell it. There are a bunch of reputable sellers but they come and go. I bought 2 lbs at hard rhino that's lasted me nearly a year. They don't sell it anymore though. r/nootropics has up to date info on current reputable sellers
