Description
Optimum Nutrition Gold Standard Pre-Workout is a powder taken before training, built around a short list of named ingredients rather than an undisclosed blend. Each 10 g scoop carries 175 mg of caffeine from natural sources, 3 g of creatine monohydrate and 1.5 g of beta-alanine, alongside L-citrulline, acetyl-L-carnitine, N-acetyl-L-tyrosine and a group of B vitamins. It comes as the 300 g tub of 30 serves in Blueberry Lemonade, Fruit Punch, Green Apple, Pineapple, Strawberry Lime and Watermelon, plus the larger 550 g tub of 55 serves in Blueberry Lemonade and Watermelon. Made up in the twenty minutes or so before training, it is for the sessions where starting is the hard part, and the caffeine sits low enough that it suits people who find the high strength pre-workouts too much.

Pre Workout
What is pre-workout?
Pre-workouts are blends you take before training to get set for your session, usually built on caffeine plus a few amino acids. Some skip the stimulants entirely, so read the panel to find the blend and caffeine level that suit you.

Is Pre Workout right for you?
Common questions
Why do pre workouts vary so much between brands?
Because there's no standard formula and no single ingredient called pre workout. It's a type of product, so each brand chooses its own blend, and two tubs on the same shelf can contain completely different ingredients at completely different doses. The ingredient panel is the only reliable way to compare them, and the caffeine figure is usually the first number to look for.
Is pre workout regulated in Australia?
The product type isn't, but everything in it is. Pre workout isn't on Australia's permitted ingredients list (Schedule 1), because it's a product category rather than an ingredient. Each ingredient inside, such as caffeine, creatine and beta-alanine, has its own rules and its own warnings. Some products are sold as foods rather than listed medicines, which changes the rules again.
