HR Labs Defib Advanced Pre Workout Catalyst is a comprehensive, heavily dosed pre-training powder engineered specifically for experienced athletes who demand more from their supplementation. Available in a refreshing Pink Lemonade flavour, each 420g tub delivers 40 servings at one scoop or 20 full-strength servings at two scoops, giving you the flexibility to match your intake to your training demands on any given day.
The formula brings together a broad spectrum of performance-relevant ingredients — including Citrulline Malate 2:1, Beta Alanine, Betaine Anhydrous, Taurine, and Acetyl-L-Carnitine — alongside specialty trademarked ingredients such as PeptiPump™ Lentil Protein Hydrolysate, Sabroxy® (Oroxylum Indicum), SalidroPure™ (Salidroside), Citicoline (CDP-Choline), and AstraGin® (Astragalus Membranaceus Root & Panax Notoginseng Root). Caffeine Anhydrous is included to contribute to the alertness and focus that many athletes seek before training sessions.
Defib is designed with transparency in mind, listing each ingredient clearly on the label. HR Labs recommends assessing your own tolerance before progressing to the two-scoop serving, where the formula’s active ingredients reach their optimal dosage levels. Whether you are heading into an intense resistance session or a demanding endurance workout, Defib Advanced Pre Workout Catalyst is built to support your preparation.
