Klean Athlete BCAA + Peak ATP Review (2024)

Klean Athlete BCAA + Peak ATP Bottle


Klean BCAA + PEAK ATP® provides a powerful combination of 2:1:1 branched-chain amino acids and 400mg of ATP® that helps enhance strength, power, and muscle gain for peak physical performance. It supports post-exercise recovery and muscle tissue repair, allowing athletes to train longer and harder.

Branched-chain amino acids (BCAAs), comprising leucine, isoleucine, and valine, are a special group of essential amino acids that play a pivotal role in stimulating muscle protein synthesis, impacting both muscle growth and recovery. 

Dietary sources of BCAAs are foods like lean meats, eggs, and nuts, but athletes and gym goers may want to add a BCAA powder to their supplement routine to ensure they are getting an adequate amount. 

Simply put, adenosine triphosphate (ATP) is a molecule that converts food into fuel in the body. Supplementation with ATP has been shown to improve performance during strength training.
