this stuff is amazing
I am on this shit right now. Have been for weeks. I usually take it for two-three months, and then take a year - half a year break. This shit makes your mind and thoughts very clear, and gives you very realistic dreams in color. Very nice if you dream about naked women. What I know about its technical side is that it suppresses adrenaline in your body, and increases the blood-flow to the brain.
It works especially nice if you combine it with an injectable like "Aktovegin" (spelling?). After a cycle on this stuff you will be smarter than you ever been in your life. Oh yeah, most importantly, there are no bad side effects.
Hope it helps.
