ok, I received my supps the other day, pramiracetam, oxiracetam and centrophenoxine. Today i dont have to work so time to try them. They come in powders and most capsule them themselves. It can be difficult to work the exact dose out but lots of googling has helped me work this out. I started with pramiracetam as its supposedly the strongest and took around 400mg, seems people respond to doses anywhere from 100mg to 1000mg. It took about an hour to kick in and it felt like the clouds/fog in my head have started to roll away, its like my brain has switched on. Now im noticing that im typing much faster then normal and my concentration is really good and alot less spelling mistakes i have to go back and fix, lol. Even reading stuff on the computer i seem to be able to read much quicker and take it all in. But at the same time i dont feel like im jumping out of my skin like some type of stimulant etc Its a calm but intense feeling of focus. I can see why people use this stuff for studying etc. I feel like super man typing hear, my brain and my fingers are co-ordinated for once. Its only been an hour and a half since i took it so we will see how the rest of the day pans out and if it affects sleep or not which i dont think it will as i dont feel hyped up, i feel like im contradicting my self but? Prami is suppose to last longer then the other racetams as well. Tomorrow im going to try the oxiracetam but if today works out great i may stick with the prami??
