  • 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.

Recent interactions between the hosts and their guests.

Is This The Most Powerful Adaptogenic Plant Extract Known To Humankind? The SCIENCE of Black Seed Oil with Dr. Michael Murray
Q: Can ThymoQuin influence sleep and stress, and how is it delivered?
There are clinical studies showing anti-stress and sleep-enhancement effects; delivery via soft gel capsules is chosen to protect volatile compounds and ensure consistent dosing, rather than using liquid oil.
Is This The Most Powerful Adaptogenic Plant Extract Known To Humankind? The SCIENCE of Black Seed Oil with Dr. Michael Murray
Q: How does ThymoQuin affect the gut microbiome at typical dosages?
At 250–1000 mg per day, ThymoQuin decreases potentially pathogenic bacteria and increases certain probiotic, health-promoting bacteria, showing a dose-dependent modulation of the microbiome.
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.
