5150 Pre-Workout In More Detail
Created by 5% Nutrition, 5150 has earned a reputation as one of the most intense pre-workout formulas on the market. Developed for experienced gym-goers who demand maximum intensity from their training sessions, it combines performance-supporting amino acids, focus-enhancing ingredients and a unique stimulant matrix to help you attack every workout with purpose.
At the heart of the formula is 4,000mg of L-Citrulline, an amino acid widely used in pre-workout supplements to support nitric oxide production, blood flow and muscle pumps. This is paired with 2,500mg of Beta-Alanine, a staple performance ingredient commonly used to support muscular endurance during high-intensity training.
To help maintain focus when training intensity rises, 5150 includes 750mg of N-Acetyl L-Tyrosine alongside Choline Bitartrate. These ingredients are frequently used in advanced pre-workout formulas to support concentration, mind-muscle connection and workout engagement.
The formula also delivers 2,000mg of Taurine, helping to support hydration, performance and overall exercise capacity during demanding training sessions.
What truly sets 5150 apart is its renowned Stim-Crazy Caffeine Complex. Featuring caffeine anhydrous, dicaffeine malate (Infinergy®), green tea extract, yerba mate, guarana, green coffee extract and cocoa alkaloids, the blend delivers a fast-hitting yet sustained stimulant experience designed for serious training days.
