I review the products I use and recommend based on the science behind them. I can't guarantee that all the products I give you will have the same effect as your doctor may say. You should do your own research, but here are some examples of some of the products I review on this site: - Neurobiologists are not "medical doctors" - they are scientists in the science of neuroscience, and have done their research for decades. Many products on this site claim to increase your "buzz" or your brain power, but don't. Most of the time you will find they just promote the product as a way to make you feel better, or make you feel like you can't do anything wrong, but don't. They are not medical doctors, and you shouldn't buy them or use their products if you don't trust their products. The brain has many different parts that help you do things like plan an airplane flight, analyze your surroundings, and even understand and remember things. The brain is a computer, and computers often need some kind of software. A computer program is just a set of instructions you give to it , and there is no need for a doctor to tell you what kind of program is right for you.
