Creatine is Bodybuilding’s ultimate supplement and for good reason for one thing. Creatine can significantly increase lean muscle mass in just two weeks. It is also responsible for improving performance in high-intensity exercise, increasing energy levels, and speeding up recovery rates. *It’s no wonder athletes who used it have such an edge over those who do not.
Glutamine is in high demand throughout the body. It is used in the gut and immune system extensively to maintain optimal performance. 60% of free-form amino acids floating in skeletal muscles is L-glutamine.
