Go Cubes from Nootrobox. Nootrobox is a San Francisco biohacking start-up that makes supplements with a specific emphasis on science and data that seem to be principally aimed at the coding/tech set, but have garnered a fan base among some of the AGEIST crew looking to stay sharp and on top of things. In particular, the Go Cubes: a perfectly measured 100mg dose of coffee with a few additions to take the edge off. Science-based dose-controlled caffeine from cold brew but without the jitters. Works for us. We are very interested in how the whole biohacking space evolves and are particularly interested in the approach Nootrobox is taking. Fascinating company.
