Which Optimum Nutrition pre-workout do you mean?
Optimum Nutrition pre-workout is not one fixed formula. Gold Standard sold in the United States differs from the UK/EU product, and Pre Advanced is a separate version. Match the country, exact name, flavor and serving weight before comparing labels or buying a replacement tub.
US Gold Standard: 175 mg caffeine, with a label caveat
The US product page advertises 175 mg caffeine, 3 g creatine monohydrate and 1.6 g beta-alanine per serving. However, its linked Blueberry Lemonade Supplement Facts image specifies a 10 g serving, about one scoop, containing 175 mg caffeine, 3 g creatine monohydrate, 1.5 g beta-alanine and 750 mg micronized L-citrulline.
The site’s Fruit Punch front-of-tub image instead shows 3.3 g creatine monohydrate and 1.6 g beta-alanine. These manufacturer materials disagree, so those amounts should not be presented as interchangeable. Check the Supplement Facts on the exact tub you receive; the shared 175 mg caffeine figure does not resolve the other differences.
UK/EU Gold Standard uses an 11 g serving
The UK manufacturer’s Blue Raspberry listing specifies 175 mg caffeine, 3.4 g creatine monohydrate providing 3 g creatine, 1.5 g beta-alanine and 750 mg citrulline per 11 g serving. Creatine and creatine monohydrate are separate entries for the same ingredient, not two doses to add together. Directions are approximately one level scoop in 350 ml cold water, with one serving per day; the 330 g container supplies 30 servings.
Pre Advanced and Platinum need separate comparisons
An ON Australia article describes Gold Standard Pre Advanced with 300 mg caffeine, 6 g L-citrulline and 3.2 g beta-alanine per serving. That article does not establish the serving weight or today’s retail availability, and its figures should not be applied to every product carrying Advanced branding.
The current UK Platinum Pre-Workout is separately listed at 200 mg caffeine, 6 g L-citrulline and 3.2 g beta-alanine per 21 g serving, approximately three level scoops. Do not assume its scoop count or caffeine amount matches Pre Advanced.
How to compare ON with Bucked Up
Compare specific formulas at their labeled serving sizes, then weigh caffeine content, ingredient amounts, price per serving and your preferences. A higher caffeine number alone does not establish a better fit. Follow the package directions, account for other caffeine sources, and avoid increasing scoops simply to match another product’s ingredient totals.
