Retatrutide Masterclass | Dosing, Side Effects, and the Framework Most People Get Wrong

I'm working on a book where I cover one peptide at a time, one chapter at a time. Alongside that, I wanted to do a masterclass on each peptide and condense down everything I know into one place. First up is Retatrutide. I cover what it actually does in your body, the two very different users that should be on it, and the dosing strategies that get debated to death online. We go through the weight loss data, the longevity data, and why I think 8 milligrams is the real ceiling for most people. I also break down once weekly versus split dosing, the heart rate question, the skin sensitivity issue, and why testosterone optimization has to come first. If you want a definitive guide on Retatrutide, this is it. My goal is that you walk away with a framework you can actually use, whether it's on yourself, your coaching clients, or your patients. Let me know what you think. I plan on doing many more of these on every peptide that matters. ⚠️ For research and entertainment purposes only. ⚠️

Episode 4 — Why the 49ers Can't Stay Healthy | Peter Cowan on EMF, Substations, and Your Hormones

If you do everything right and still feel off, this episode is for you. I sat down with Peter Cowan, a quantum biology practitioner and environmental health investigator who got chronically sick from EMF exposure, walked away from Silicon Valley, and spent years figuring out why on his own. Peter's Substack series on the San Francisco 49ers, who practice and play right next to a power substation, is some of the most compelling EMF research I've seen anywhere. We covered the EMF checklist anyone can run at home, the mitochondrial mechanism behind oxidative stress from magnetic fields, how EMF disrupts the cortisol and melatonin cycle that drives your testosterone, why pre-sunrise workouts under fluorescent lights are doing more damage than most people realize, and the three-pronged light protocol that took Peter's testosterone from 437 to over 800.

This Peptide Works 10X Faster Than SSRIs (Here's How)

👇 ALL MY LINKS IN ONE PLACE https://hunterwilliamshealth.com/links PE-22-28 is one of those peptides almost nobody is talking about, and I think that's a shame. In this episode I walk you through what it is, how it works, and why I'd put it in the antidepressant category before I'd call it a true nootropic. I get into the background as an optimized analogue of spadin, the TREK-1 channel inhibition that drives the effect, and the downstream impact on BDNF, synaptogenesis, and neuroinflammation. I also cover the part most people care about: the rapid antidepressant onset, usually around four days, versus the three to four weeks you wait on a typical SSRI. From there I share the dosing protocol I've been using on myself, including a four-on, three-off cycle to keep tolerance low, plus what I've noticed in terms of mood, mental energy, and the lack of any real come-down or withdrawal. I'm not saying this is a cure for depression. Depression is multifaceted and deserves a multifaceted approach. But if you need something to help get you out of the hole and back into the habits that actually move the needle, PE-22-28 is worth knowing about.
