"The results themselves were not surprising. The most effective nootropics were caffeine – which pretty much everyone in the world knows works – and modafinil (along with its fellow -afinils) which has been proven to work by countless studies and is a prescription drug much used by the medical establishment. Below these two, the most effective “exotic” nootropics were phenylpiracetam and coluracetam. I suspect that despite the nootropic community’s enthusiasm about phenylpiracetam it mostly just works as a mild stimulant not too different from other stimulants like amphetamines. Coluracetam, a very new and pretty unique substance currently being investigated as an Alzheimer’s treatment, is more exciting." • #схватил_за_мозг - #ноотропы - #занимательная_медицина - × × ×

“Overall I was not too impressed with the results of this survey. No unexpected substances jumped out as promising, there was a very wide distribution from “useless” to “life-changing” in nearly everything except the -afinils, and it was very hard to find much of a dose-response relationship anywhere. There is no “smoking gun” for most these substances being definitely-exciting, aside from the ones like modafinil that we were already aware of.” - × × ×
