GMP Informed Choice Third-Party Tested

Gold Standard Pre-Workout from Optimum Nutrition is a moderate-stimulant formula containing 175mg naturally sourced caffeine alongside creatine monohydrate, beta-alanine, and AstraGin for enhanced absorption. Designed for those who want reliable energy without overwhelming stimulation, it sits perfectly in the middle ground between stim-free and hardcore options.

AI Review Summary

Optimum Nutrition Gold Standard Pre-Workout is a well-rounded, moderate-stimulant option from one of the most trusted names in sports nutrition. The 175mg naturally sourced caffeine provides clean energy, and the inclusion of creatine is a nice touch. However, the citrulline dose at 750mg is far below clinical levels, and beta-alanine at 1.5g is also underdosed. Best for those who want gentle energy rather than maximum performance enhancement.

Clean Label Analysis

Uses both sucralose and acesulfame potassium for sweetening, which is common but not ideal. The active doses are generally below clinical thresholds, particularly citrulline at just 750mg (clinical dose is 6-8g). Prioritises moderate dosing over maximal performance.
