Racetams

     Next to good old caffeine, racetams are the oldest and most widely recognized nootropics substance, and Piracetam is the oldest and most well studied of the bunch.  I first started taking piracetam about eight years ago and at that time I was looking for a cognitive benefit, and while I did find some benefits, for example, the first time I took it I then went to a local bar that used to make really good fish and chips (it has sold and they are now shit), it was very busy almost all the tables were occupied.  I noticed subtleties in the color of the wood door that I had never noticed before.  It was as if someone turned the vibrance knob up on the world television set.  The second thing I noticed was that I could follow half a dozen conversations at half a dozen different tables simultaneously.  The last thing was that I could remember a few more digits in a digit string memory test, enough to remember a ten digit telephone number sometimes heard several days before.  But that was about it as far as cognitive benefit, not a lot of practical benefit.  I continued to take it for several months.  Now when I started I had tinnitus that was at times severe enough to interfere with the ability to hear someone talking to me face to face.  But about three months into it I was out for a walk late at night and I was on a street with a cemetery on one side and back yards of houses on the other, and I was hearing a conversation clearly that sounded close by, yet nobody was visible.  I finally spotted the people talking, they were two blocks away!  I had measured my hearing frequency response once before and it rolled off severely after 8Khz, I measured it again, now I could hear all the way up to 17 KHz, I stopped exploding tweeters on my stereo, and the constant whine was gone.  After about a year I stopped talking it and after about three months the tinnitus returned and frequency response started falling off, so I went back to taking it and hearing mostly returned, more attenuation this time between 13Khz and 17Khz, but before I couldn't hear anything past 8KHz so still worth while.  Piracetam is a good starting place, it's non-toxic, or at least not much more than water, table salt is far more toxic.  My recommendation, start at 800mg and work your way up, if you start to notice a positive effect continue raising the dose until you don't get more effect or you reach around 4800mg/day.  If you keep raising beyond that point it will start to lose effect.  Piracetam and all racetams really, have an inverted U response curve.  The goal is to find the top of that inverted U.
