Meet the Founder
Brennan Decker
I started at 302 pounds. I tried every diet, every app, every approach. Nothing stuck until I found peptide therapy.
Within months, I'd lost over 70 pounds. Not through some magic pill, but through a systematic, data-driven approach to my protocol. I tracked every dose, every measurement, every blood marker. I ran my peptide protocol the same way I run products at work: with data, discipline, and documentation.
The problem? I was doing all of this in spreadsheets and Reddit threads. There was no single place to track my protocol, understand my compounds, and make informed decisions about my health.
So I built one.
pepguide.ai is the tool I wished existed when I started this journey. It is built on research, not bro science. It is designed for real people making real decisions about their health. And it will never sell you a single peptide.
I am a product manager by trade, working at Fortune 500 scale with hundreds of millions of users. I brought that same rigor to building this platform. Every compound profile cites real research. Every feature exists because I needed it myself.
