The problem, and the reason they’re out, is because of the FDA. While I agree in principal I wish I didn’t have to search websites for piracetam that are all out of stock due to customs not letting them through.
My own interest in nootropics is some years behind me now, but I note that Nootropics Depot does have bulk phenylpiracetam powder in stock, and I don't recall filling my own capsules to have been especially difficult. Slow and exacting work, to be sure, but also the kind of work that a good podcast or TV show helps go faster. With a little practice and a good capsule filling machine, you can make a month's worth of doses in a couple of hours - cheaper than buying prefilled capsules, too.
