The Hunter Williams Podcast

Every question that came in over the last month. No filters, no shortcuts. This is the April 2026 edition of the solo Q&A and Hunter covers everything from women's hormone optimization and PCOS to vasectomy impacts on men's health, peptides for neurological conditions, bioregulator cycling protocols, and everything in between.

In today's episode, we're taking a detour from our usual peptide discussions to dive into one of my absolute favorite biohacking devices: the carbon dioxide therapy inhaler from CarboGenetics. I know what you're thinking—why would we want to inhale CO2 when we usually focus on getting more oxygen? It all comes down to a fascinating physiological mechanism called the Bohr effect. I'll break down the science of how inhaling small amounts of carbon dioxide actually forces your hemoglobin to release more oxygen into your tissues, significantly boosting cerebral blood flow, accelerating wound healing, and enhancing exercise performance. 

We'll explore the history of CO2 therapy, from ancient volcanic vents to modern clinical studies showing impressive results in tumor oxygenation and hearing recovery. I'll also share my personal routine for using the device, including the optimal concentrations and timing for morning wakefulness, pre-workout endurance, and afternoon brain energy. Whether you're a hard-charging entrepreneur looking to regulate your nervous system or an athlete wanting an edge in the gym, this affordable biohack might just be the missing piece in your wellness routine. Tune in to learn how to harness the power of the carbonated body!

Today I'm breaking down something that's been blowing up in the peptide world. The FDA just made a major announcement about moving 19 popular peptides from Category 2 to Category 1. And I want to share my honest thoughts on what this actually means for you.
First I walk through how we got here. The Biden administration's original scheduling decision. The rise of the research peptide market. And why roughly four out of five peptides consumed in the US today come from research companies.
Then I get into what the FDA is actually proposing. The July hearing. The February 2027 timeline. And what Category 1 status would mean for compounding pharmacies and telehealth clinics.
But here's where it gets interesting. I share my prediction on where prices are headed and why I think we'll eventually see price parity between prescribed and research peptides. I also dig into what I think is a quiet quid pro quo happening between Big Pharma and the FDA around GLP-1s.
This is speculation on my part. I'm not a doctor or a lawyer. But I wanted to give you my honest read on where this is all going. Let me know your thoughts in the comments.
