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.
