Pre-Workout PRO ST is a high-quality powdered pre-workout supplement with a perfectly balanced composition scientifically proven by the University of Greenwich. It provides all the necessary nutrients to enhance performance in both strength and endurance training and competition.

  • Extra essential amino acids
  • With caffeine and nitric oxide precursors
  • Low in carbohydrates and no added sugars
  • Scientifically proven efficacy through our own study

Essential Amino Acids

Fundamental for optimal muscle function during activity. Pre-workout intake has been shown to delay fatigue and enhance recovery by reducing muscle breakdown. Delivered in an optimal ratio similar to that of muscle mass.

Nitric Oxide Precursors (NO)

The exchange between Citrulline and Arginine in the presence of oxygen releases NO. When it binds to specific receptors, it causes vasodilation, increasing blood and nutrient flow to active muscles and potentially improving performance.

Taurine

Has antioxidant, metabolic, and ergogenic effects. When combined with other ingredients, it improves muscle endurance during exercise and stabilizes cell membranes, facilitating the transport of key minerals.

Tyrosine

Enhances focus and concentration when combined with caffeine—key for maximum performance in training or competition.

Betaine

This glycine derivative enhances performance by boosting creatine resynthesis and increasing NO levels. It also improves total workload to fatigue as well as strength and power output.

Acetyl-L-Carnitine

Crosses the blood-brain barrier and acts on two fronts: improves mitochondrial metabolism by donating acetyl groups (acetyl-CoA) and supports cognitive function by aiding acetylcholine synthesis.

Caffeine and Yerba Mate

Includes pure caffeine and yerba mate extract, the top ingredient for boosting endurance and strength. Stimulates the central nervous system, delays fatigue, optimizes glycogen and fat use, and enhances muscle contraction—especially under fatigue.

Like all Crown Sport Nutrition products, it offers outstanding taste and digestibility.

Scientific study published in Nutrients: The ingredient matrix was tested using 2 servings of Pre-Workout PRO ST (30 g) with approximately 16 g of added carbohydrates. To replicate the study, add 2/3 of a serving of Isodrink & Energy Lemon (about 20 g) to maximize effectiveness.
