SS-31 continues to be one of my favorite peptides of all time, and the more data that comes out on it, the more I think every person over 25 has a use case for it.
In this masterclass, I'm breaking down everything I know about SS-31. We cover what it actually does at the cellular level, why it's the first FDA-approved mitochondrial peptide, and why it works differently than almost every other peptide out there. No receptor binding. It goes inside your cells, binds to cardiolipin, and stabilizes the structure of your mitochondria.
I walk through the three dosing tiers I use with people, my take on cycling, why I run SS-31 before MOTS-c, how to stack it with GLPs, GH peptides, and the healing peptides, and what to actually track when you're on it. I also cover the troubleshooting stuff people ask me about constantly. Why don't I feel anything? Should I cycle? What about the headaches in the first two weeks?
If you're a clinician or just researching for yourself, this is the complete user's guide.
