Episode notes
Early Injury Shaped Mentzer's Approach
- Mike Mentzer began using anabolics very young and injured his shoulder early in his career.
- That injury influenced his turn toward high-intensity, lower-frequency training and recovery-focused programming.
Anabolics Raise Tendon Rupture Risk
- Multiple studies show anabolic steroid use raises tendon and ligament rupture risk across recreational and TRT dosages.
- The increased risk appears substantial and not limited to high-dose recreational users.
Why Tendons Weaken Despite Growing
- Steroids increase collagen synthesis but suppress collagen breakdown, producing larger yet disorganized tendons.
- Tendon stiffness depends on structural remodeling, so inhibited breakdown leads to weaker, fibrotic tendons despite size gains.
