Beta-X contains a naturally occurring amino acid that is the precursor to a critically important di-peptide called carnosine. Carnosine is a substance formed from beta-alanine that is naturally occurring in muscle tissue - primarily in fast twitch muscle fibers. Carnosine's primary function in muscle is to buffer hydrogen ions (H+).

What does buffering H+ have to do with anything? H+ is a byproduct of muscle contraction from the breakdown of ATP (adenosine triphosphate) - the cellular fuel that powers muscles. This training induced increase in H+ is called metabolic acidosis. The more H+ that is generated the more the pH level in your muscles fall (becomes acid). When this happens muscles start to burn and rapid exhaustion occurs stopping muscle contraction ability dead in its tracks. It's this generation of H+ that forces you to stop a set - it causes muscle failure. And this H+ is generated from the muscle contractions that are required to do the reps in the set.

Weight training and literally any other physical activity generates the H+ that leads to muscle fatigue, drop in force production and ultimately muscle failure. You have always heard, "Go to failure", well this is what is happening and what causes it.

Now, imagine being able to get 3 more reps than you normally do on a set. Imagine jumping up in weight on each set. Imagine training heavier and harder than you ever have before. What's going to happen? You're going to start packing on muscle like nobody's business that's what. And that's what Beta-X is designed to do.

Beta-X allows you to train heavier, train harder, and train longer. And on top of this, Beta-X helps you recover faster - both between sets and between workouts. Wrap this all together and you're building more muscle and getting stronger much faster.*
