LEAN
Transparent Labs
Overview
Transparent Labs LEAN Pre-Workout is designed to enhance energy, focus, and fat metabolism during workouts. It includes several well-researched ingredients, such as citrulline malate, beta-alanine, and acetyl-l-carnitine, at clinically relevant doses. The combination of caffeine and theanine aims to provide a balanced stimulant effect. However, the supplement also contains a high dose of chromium, which may not be beneficial for everyone, and users may experience paresthesia from beta-alanine.
