* This product  is not for those who are not working out or have started working out recently.

ONLY FOR EXPERIENCED ATHLETES.

You take pride in a strong finish. But it's what comes beforehand that reveals your True Strength. This level of effort takes energy, focus and endurance. It takes starting your workout before you even hit the gym with new Optimum Nutrition Gold Standard Pre-Workout, formulated with only premium banned substance tested ingredients by the foremost experts in sports supplement nutrition.

Caution:
After a few days of use of this product (as well as most of pre-workouts), you may notice a "rock" feature. This in no way implies alteration of the product. Instead, it is a natural process, which is due to the existence of many "hygroscopic" ingredients (such as Arginine and Beta Alanine), which means that these ingredients attract water and hold its molecules. So when the package opens and the product comes in contact with the humidity of the environment, the poweder is "thickened".
It is perfectly normal and all that the consumer needs is to smash the larger pieces with a spoon to facilitate its dissolution without altering the product.
The product is recommended to be consumed within 2-4 weeks after opening the package. The longer the package is left, the more the powder lumpier it will get.
