# Dr. Daniel Craighead & Mayo Clinic Rapid Arterial Compliance & Endothelial NO Protocol - Longevity Protocol Stack Audit

> **Editorial Summary**: Developed by Dr. Daniel Craighead at UC Boulder and validated by Mayo Clinic trials. Combines High-Resistance Inspiratory Muscle Strength Training (30 breaths/day at 75% PImax dropping systolic BP by -9 mmHg and boosting FMD by +45%), Isometric Handgrip holds, cocoa epicatechin, and Aged Garlic Extract to restore youthful arterial elasticity, reduce central pulse wave velocity, and halt coronary soft plaque progression.
