Longtime biohacker and nootropics aficionado Abelard Lindsey swoops in for his (record-breaking) third appearance on Smart Drug Smarts.  Jesse picks his brain on how stacks get developed, with a particular focus on Axon Labs’ flagship cognitive mix, Nexus. They examine each ingredient - Aniracetam, CDP Choline, Phosphatidylserine and Pycnogenol® - and the purpose of each one inside the stack…  And also the how's and when's of their own personal use of Nexus.

In the before-and-after segments, the action continues — with hostage rescue simulations and what they can teach us about memory, liberal mentions of the word “poop,” and another way that you can get to know Jesse - the man behind the mic.
