Description

Unleash your full athletic potential and dominate every gym session with Optimum Nutrition Gold Standard Pre-Workout. Crafted for athletes, bodybuilders, and active fitness enthusiasts, this premium energy formula combines trusted, high-grade ingredients to deliver clean energy, razor-sharp focus, and enhanced muscle endurance without the harsh post-workout crash.

Key Benefits & Features

  • Explosive Energy & Focus: Formulated with 175mg of natural caffeine derived from tea and coffee beans to heighten mental drive and intensity.

  • Enhanced Muscle Endurance: Packed with 1.5g of CarnoSyn® Beta-Alanine to help buffer lactic acid accumulation and delay muscle fatigue.

  • Pump & Blood Flow Support: Includes 750mg of Micronized L-Citrulline to encourage nitric oxide production and enhanced vascularity.

  • Performance & Power Amplification: Fortified with Creapure® Creatine Monohydrate to support ATP regeneration and explosive physical output.

  • Banned Substance Tested: Rigorously screen-tested under the Informed-Choice program for absolute peace of mind and quality assurance.

How It Works

Optimum Nutrition Gold Standard Pre-Workout relies on a synergy of performance-proven active ingredients. Natural caffeine triggers central nervous system alertness, providing sustained energy without jittery side effects. CarnoSyn® Beta-Alanine increases muscle carnosine levels, allowing your muscle fibers to fight off acidity during intense, high-repetition sets.

Simultaneously, Micronized L-Citrulline drives nutrient-rich blood flow straight to working muscles, while Creapure® Creatine Monohydrate fuels cellular energy reserves (ATP). This combination ensures you can push harder, lift heavier, and maintain peak athletic output from your first rep to your last.

Recommended Use

Mix 1 scoop (approx. 10g) with 180–240 ml (6–8 oz) of cold water and consume 20–30 minutes prior to training. To assess tolerance, start with a 1/2 scoop serving. Do not consume within 4–6 hours of sleep or exceed 1 scoop in a 24-hour period.

The pineapple and blue lemonade are both really good flavours, but the pineapple comes out on top. The watermelon is just a bit too sweet

Was a little nervous buying this product, as I’ve heard of bad side effects with caffeine type products. This Completely surprised me ... it tastes great, no side effects and Easy to use.
