I had been interested in some of the various smart drugs for quite a while, and piracetam was one of the top ones I wanted to try.
Ordering some from an online vendor, I got 800mg orange 'Nootropil' tablets manufactured by UCB Pharma. The tablets contain 800mg per unit and the tablets themselves weigh ~850mg. I was surprised that 800mg of active compound could fit into a tablet weighing only 850mg, but after weighing a few more commercial tablets (acetaminophen, ibuprofen, etc) it seems as if it is quite likely.
For the first week, my partner and I tried taking 3 per day (2400mg per day at the dosage marked on the packaging). The effects were not detectable and definitely not above possible placebo. We continued taking 3 per day for about a week, a couple days we took 4 per day, spread out with at least 3 hours between each dose. No effects of any kind were reliably noted.
A couple times I wondered if perhaps I was less foggy-minded that I normally am, but this never rose to a level at which I could discern any real effects. I will continue to take them for another few weeks to see if I can detect anything further and will also try pushing the dose up.
I think next week I'll try two tablets per dose.
