Optimum Nutrition Gold Standard Pre-Workout
by Optimum Nutrition
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.
