Dave Asprey is a 41-year-old nootropics enthusiast, and, according to his recent CNN profile, he can "hack his own biology." 

The Silicon Valley entrepreneur spent 15 years and more than $300,000 developing the perfect cocktail of “natural supplements”, and every morning, he wolfs down some homeopathic-sounding goos. Plus a pile of pills to supercharge his cognitive functions, because what he really loves is "stacks."

Asprey "spews" and consumes "names you probably have never heard before: Piracetam, Aniracetam, CILTEP, Methyl, Cobalamin." What's all this, then? Aniracetam, for example, is an ampakine nootropic. Like most of these pills, which are intended to treat known disorders and diseases, this one's for Alzheimer's. Healthy consumers could exhibit some "possible cognition-enhancing effects," speficially, feeling well-rested and clear-minded. Modafinil, used to treat narcolepsy, could help you stay focused long into the evening hours, and so on. Seems like Asprey is mixing various "smart drugs" with possible, ranging brain level ups, which sounds cool, but also, like a worrisome overkill.

As part of his "stacks" lifestyle, Asprey claims to have increased his IQ by 20 points. What he has for certain is a very popular health podcast.
