Dr. Scott Sherr is a clinician, hyperbaric medicine specialist, co-founder of Troscriptions, and one of the founding faculty of the Health Optimization Medicine and Practice nonprofit — and in this return episode, he comes with a very different perspective than his first appearance. What changed? He stopped putting everyone in the chamber. In this conversation, Scott and Freddie unpack the two hyperbaric chamber deaths that shook the industry in 2025 — what actually went wrong, what safety standards clinics and home users are missing, and why a sympathetically dominant nervous system may render even the best biohacking tools completely ineffective. From there they go deep on mitochondrial function as the master upstream driver of energy, detox, digestion, healing, and longevity — and why most people need to subtractbefore they can optimize.

The second half of this episode is a complete masterclass on methylene blue — what it actually does at the mitochondrial level, how to find your ideal dose (hint: you'll know within three to five days), why 94% of American adults are metabolically compromised enough to benefit from it, and how one ultramarathoner shaved three hours off his Leadville 100 finish time using it strategically. Scott and Freddie also tackle epigenetic age testing, immunosenescence, the dopamine-draining effects of smartphones on libido and focus, and why screen time may be the most underrated threat to your nervous system recovery. Plus — a full breakdown of the Troscriptions product suite: TruCalm, TruZ, TruImmune, and methylene blue's role in each.
