A stim free pre workout is a supplement that does not contain caffeine or other stimulants. Stimulant free pre workouts are ideal for those who want to avoid stimulants, whether that's due to late night workouts, going through a caffeine cleanse, or simply don't handle stimulants well.
Non stim pre workouts are formulated for increasing power, endurance, and pumps. They support blood flow, muscle growth, and recovery. These can be safely stacked with almost any other product.
