Author: Sal Di Stefano, Adam Schafer, Justin Andrews, Doug Egge April 20, 2026 Duration: 1:18:23

Jay Campbell is BACK... and this time he's talking about all the cutting edge peptides for building muscle. We're talking follistatin derivatives with 19 day half lives, super retatrutide that you might only need to inject once every TWO MONTHS, and why these compounds could be the future of building lean mass without the brutal side effects.

Jay tells stories about the legendary Dan Duchaine. You'll learn the REAL history of cyclical ketogenic dieting, why going zero carb all week then carb loading on weekends was revolutionary for bodybuilders in the 90s.

Here's where it gets controversial... Jay explains why aromatase inhibitors are absolutely DESTROYING modern bodybuilding physiques.
