2912: SS-31 Peptide Benefits: Why Ben Pakulski Says This Is the Most Exciting Peptide Right Now

Ben Pakulski
Show Notes

IFBB pro bodybuilder and performance coach Ben Pakulski joins the Mind Pump hosts for a deep dive into peptides, performance, and the lessons of a 20-year bodybuilding career. He explains why SS-31 is the most exciting peptide right now for mitochondrial repair, delivers a stark warning about the unregulated peptide market (90%+ from China), and gives an update on myostatin inhibition science. The conversation also covers his unlikely path from a 160-pound teenager to a 240-pound natural athlete, competing sick at the Arnold Classic and still taking second, and why bodybuilding was never his identity—just something he did. The group also explores GLP-1 risks, the fragility epidemic, genetic testing for coaching, and why the hard work of training is the actual prize.
