WARNING: After a few days of using this product, you may notice a characteristic "hardening" of it. This does not indicate any alteration of the product. It is a natural process that occurs due to the presence of many "hygroscopic" ingredients, meaning these ingredients attract water.

• Arginine and Beta-Alanine attract moisture.
• When the package is opened and the product comes into contact with environmental moisture, the powder "compacts".
• This is normal, and all you need to do is crush the larger pieces with a spoon.
• The product is recommended to be consumed within 2-4 weeks of opening the package.
• The longer the package remains open, the more the powder will clump.
