Austin, Texas · August 4, 2026I've seen this movie before.
Five years ago, you helped me tackle the biggest healthcare problem of our generation.
During COVID, America discovered we couldn't manufacture something as basic as a mask. We built Armbrust USA to help fix that. Today, our masks and nitrile gloves are used by families, hospitals, the VA, and retailers across the country, including Target.
A few years later, I found myself on the other side of the exam room.
My doctor recommended I try a GLP-1. I spent months reading the research before saying yes. When I finally started, the standard treatment plan didn't work well for me.
So my doctor and I personalized it. We changed the dose. We changed the timing. We slowed everything down.
It worked.
Then I realized I'd seen this movie before. We were always fighting against foreign masks that didn't meet US quality standards.
A bad peptide can kill you.
But the biggest surprise wasn't about safety. It was personalization.
I hadn't discovered a better drug. I'd discovered a better way to use it.
If personalizing my treatment worked so well, why isn't it the standard?
That's why we started RonanRx.
Over the next five days, I'll share the peptides that have had the biggest impact on my own life, what the research says, and why I believe personalized medicine is the next major shift in healthcare.
I hope you'll follow along.
