Rule 1 Lean is a clean, stimulant-assisted metabolic support formula built to help athletes dial in body composition without losing strength or energy. Designed for performance-focused fat loss, it supports fuel utilization, appetite control, and natural thermogenesis. This formula brings together carnitine, tyrosine, taurine, and B-vitamins for energy metabolism, while Capsimax®, Grains of Paradise, and decaffeinated green tea extract work to elevate thermogenic output without overwhelming stim levels. Coconut water powder helps maintain hydration, and BioPerine® enhances absorption so every ingredient hits with intent. Whether you're cutting for a season, making weight, or simply tightening up your physique, Rule 1 Lean supports fat loss while keeping you training at 100%.
