Boundless
About
Boundless is a wide-ranging manual covering cognition, exercise, nutrition, sleep, recovery, supplements, and longevity practices. Ben Greenfield’s approach is explicitly self-experimental and technology-friendly, which makes it useful as a map of the biohacking landscape but also increases the need to check claims and conflicts.
Scientific Research
Recommendations span supplements, devices, therapies, and lifestyle; evidence and conflicts vary widely, so check each claim independently.
