  • Great honest podcast

    Love that I found a podcast that is for biohacking but also not afraid to share faith. Love that he shares his faith in GOD unapologetically and ties in health and family.

    I’ve used numerous methods that Ben talks about for athletic performance. They’ve all been spot on and have helped me progress my career. I think most people who talk bad about this show are simply unhealthy beings and maybe need a foundational step forward first to see that these things actually do work. He’s ahead of the curve in a lot of topics. Things you hear today you’ll hear in 2-3 hears Huberman talking about. He’s ahead of them all in my opinion.

Talking Points

Recent interactions between the hosts and their guests.

BIG Peptide News (Must-Listen!): What Really Happened In Washington DC & A 7 Peptide Breakdown, With Dr. Matt Cook.
Q: How does putting a peptide on the bulk list affect its use?
Being on the bulk list allows compounding pharmacies to prepare it for patients, which enables broader access and off-label prescribing by physicians within approved indications.
BIG Peptide News (Must-Listen!): What Really Happened In Washington DC & A 7 Peptide Breakdown, With Dr. Matt Cook.
Q: What is the process for deciding which peptides can be compounded again?
The FDA committee reviews data and literature for each peptide, votes on whether it should be added back to the bulk list, and then physicians can use it for patients under those guidelines; further regulatory steps may follow.
In Defense Of Sunlight: The *Real Truth* About The Sun, Vitamin D, UVA, UVB, Sunscreen & More, With Rowan Jacobsen.
Q: What practical sun exposure recommendations would you give to listeners today?
Aim for regular, moderate sun exposure to support vitamin D and nitric oxide production while avoiding sunburn. Use protective strategies like hats, clothing, and timing of outdoor activities to minimize peak burn risk, and consider targeted, safer use of sunscreen focusing on high-exposure areas. For those in northern latitudes or with limited sun, consider midday exposure and potential Vitamin D supplementation or UVB-specific devices to maintain adequate levels.
In Defense Of Sunlight: The *Real Truth* About The Sun, Vitamin D, UVA, UVB, Sunscreen & More, With Rowan Jacobsen.
Q: What is the central thesis of your book, and how does it challenge conventional sun safety messaging?
The central thesis is that the current paradigm of avoiding sun exposure and relying on sunscreen year-round is not strongly supported by the full body of scientific evidence. Instead, a balanced approach that considers UVA/UVB differences, intermittent exposure, and the broader health benefits of sunlight—such as nitric oxide production and vitamin D metabolism—offers a healthier framework. This includes recognizing how historical messaging may have amplified fear and how modern research suggests nuanced sun strategies rather than blanket avoidance.
Why Do We Still Use 150-Year-Old Technology To Measure the #1 Killer of Humans Worldwide? The New Approach To Blood Pressure Measurement With Tom Moss.
Q: How accurate is the Ring compared to a traditional cuff, and why did you choose a ring form factor?
The Ring is designed to be cuff-free and accurate without calibration from a cuff, leveraging PPG-based sensors and a physiological model to read pulsatile waveforms. The ring form offers optimal skin contact, minimal motion, and better sleeping compatibility, which are crucial for continuous, real-time measurements.
