Medicine is moving fast. Faster than most clinical practice is designed to keep up with. The research on peptides, hormones, metabolic health, and longevity is genuinely exciting but this “frontier of medicine” comes with real risk when information outpaces informed, nuanced interpretation.
That's the gap I'm trying to close. Not by oversimplifying through viral soundbites, and not by waiting for perfect evidence that may be decades away. But by reading the research carefully, working with patients daily, and sharing what I'm actually learning so people can make informed decisions about interventions that could genuinely change their health.
I think everyone deserves access to that.
What that looks like: During the day I'm a Medical Director at a functional medicine practice, working 1:1 with patients. Nights and weekends, I go deeper to stay current on the research and figure out how to make it actually useful to people outside a clinical setting. I'm deeply curious about this space, and I want to bring practitioners and patients along for that.
Meet Quinn Stillson, MD.
From the ER to Longevity Medicine
During my ER residency on the South Side of Chicago, I treated multiple preventable heart attacks and strokes every shift. And almost every patient had the same story: decades of metabolic dysfunction, ignored warning signs, and a reliance on the ER as a bandaid solution on a much bigger problem.
That's when I knew emergency medicine wasn't for me. I didn't want to treat the end result of poor health…I wanted to prevent it in the first place.
So I pivoted into longevity medicine.
I completed a Fellowship in Longevity Medicine through the American Academy of Anti-Aging Medicine (A4M), earned my Peptide Therapy certification, and became board-certified in Anti-Aging & Regenerative Medicine.
I also went back to something I'd done during medical school: coaching. As a Certified Strength and Conditioning Specialist (CSCS), I deeply believe that the human body is capable of way more than just avoiding disease. We can optimize for performance, recovery, and longevity. But it takes a good coach to achieve that.
This time, coaching looked like starting the YouTube channel to share my learnings at scale and challenge myself to create evidence-based protocols that real people can follow. That’s what I want people to get from my channel.
There is a lot of uncertainty and noise when it comes to medicine. However, I truly believe that evidence-based voices help drive the field forward for everyone. When we do that, we don't just save lives (which is important work), we extend the number of healthy years people get to live (which is also important work).
I'm passionate about longevity medicine, and I think we're at the frontier of something important. If you listen to or learn from Quinn Stillson MD, thank you. If you want to learn more or reach out, I'd love to hear from you.

How I Think About This Work
Here's my philosophy: Start with the basics: sleep, nutrition, exercise. If those aren't solid, nothing else matters.
But once you've got the foundation? There are interventions that can genuinely extend healthspan. Peptides. Hormone optimization. Targeted supplementation.
The challenge is that most of these interventions are at the frontier of medicine, which pushes information on them to the extremes. On one end, you have clinicians who won’t touch anything unless there are decades of human trials. Promising tools get dismissed…not because they’re necessarily unsafe, but because they’re new. On the other end, you have people self-experimenting with protocols they found online, with zero understanding of dosing, sourcing, or risk.
Both approaches can be harmful.
My goal is to help bridge this gap by reading the research, explaining what the evidence actually shows, and flagging where it doesn’t exist yet. You are in charge of your health, but it gets easier when the content available online is evidence-based.
