BCAAs are the essential amino acids leucine, isoleucine and valine, which comprise around 20% of your body’s muscle protein. They’re “essential” because your body doesn’t make them on its own—you have to get them from food and workout supplements. Like other amino acids, they’re the building blocks of protein. But these particular aminos may also help preserve muscle glycogen , which fuel your muscles and may help minimize protein breakdown during exercise.
Caffeine is a natural stimulant that works by stimulating the brain and central nervous system, helping you stay alert and prevent the onset of tiredness. Our caffeine is sourced from green coffee beans to give you a pre-workout boost as well as a sustained release of energy throughout your workout.
