Optimum Nutrition's new Gold Standard Pre-Workout unleashes amplified energy, focus, and supports enhanced endurance to help you reach the pinnacle of your game, crush your next set, get that last rep, and achieve some true gains.

This formula raises the bar by providing you with only what you need to achieve your true strength - made with select banned substance free ingredients, including caffeine from only natural sources (tea and coffee bean) to help dial in intense energy, mental alertness, and sharp focus before you hit the gym.

Gold Standard Pre-Workout is also made with only premium ingredients including CarnoSyn beta-alanine, which supports your intramuscular buffering system to help you train harder, longer and German-engineered Creapure creatine monohydrate - one of the industry's most well-known providers of high purity creatine monohydrate.

Finally, the Gold Standard of pre-workouts includes L-citrulline malate — a precursor to nitric oxide (NO) synthesis and other ingredients such as AstraGIN and acetyl-L-carnitine HCI to round out this powerful formulation.
Mix each scoop with 6-8 oz of water and consume 20-30 minutes before training. Start with 1 scoop or less to assess your tolerance. DO NOT EXCEED 2 SCOOPS PER DAY.
