The verdict
Solid but dose-conservative.
For lifters chasing training output.

Good energy profile with caffeine at 175mg (close to optimal) and creatine at 3g. But the pump and endurance ingredients are significantly underdosed. L-Citrulline at 750mg is only 12% of the 6g optimal. Beta-Alanine at 1.5g is 47% of the 3.2g optimal. These are the leading ingredients for a pre-workout beyond stimulation, and both fall well short.

Also earned
Clinical dose of Creatine Monohydrate.Effective, moderate dose of Caffeine.Good range of B vitamins.

The read

Optimum Nutrition Optimum Nutrition Gold Standard Pre-Workout: a solid everyday formula. Lead: Vitamin D3 at 12.5 mcg. Good energy profile with caffeine at 175mg (close to optimal) and creatine at 3g. The primary is covered; some supporting doses sit below the studied amounts.

Pre-workout for energy, strength, and some endurance.. The score reflects the strong creatine and caffeine doses, which are crucial for a pre-workout. However, the severe underdosing of L-Citrulline and Beta-Alanine, along with other underdosed ingredients and proprietary blends, significantly detracts from its overall effectiveness and transparency.
