The 'racetams have been around since the 1970's. I was generally referring to the 'racetams when I made my statement. They are all just derivatives os Piracetam, so, essentially, they are the same compound. So, generally speaking, there have been hundreds of 'racetam studies done on humans since the 1970's. But that really is just splitting hairs.

It is only a prescription drug in two European countries.

The FDA won't approve any drug that is marketed as a cognitive enhancer, regardless of the research that has been done on it. Don't know why this is, it just is. Also, because of patent issues, no drug company wants to push this through for FDA clearance. But, the FDA is certainly not the end-all-be-all of the prescription drug manufacturing world. Just look up how ritallin was cleared and you'll know what I'm talking about.

It is recommended to take a choline supplement while taking any 'racetam.
It does deplete your brain of choline, which I have experienced first hand. Makes you very tired and groggy, but as soon as you take a choline pill, you're right as rain again.

The research has proven that it can improve any brain injured persons condition. The degree of improvement varies, but some research has stated seeing a 65% improvement in subjects studied. Not saying that it is a cure-all, but most brain injured people would agree that even a 10% improvement can be pretty dramatic.

It is pretty costly to get right now as there aren't any manufactures who make it in bulk anymore, except for Piracetam. A months supply will cost around $40. However, most co-pays on prescription drugs now cost around that as well.

Overall, I would say that it is definitely worth giving a try for a month. If it doesn't work, you're only out $40 bucks and at least you tried it.
