Creatine is primarily responsible for increasing the strength needed for training, which directly stimulates muscle mass growth. By taking creatine, we can increase our sports performance by 10 to 15%. This means that in training, we can do more repetitions and lift heavier weights than usual. As a result, we increase the load on our muscles, which directly promotes their additional growth and development. The most significant benefits are seen by professional athletes accustomed to intense training, as it's challenging for them to stimulate further muscle growth.
