How it works

Muscle adapts to training through signals as well as raw material. PeptiStrong is a patented network of peptides produced by breaking down fava bean (Vicia faba) protein. It complements your protein intake rather than replacing it, and it does the most when combined with resistance training.*

About the formula
PeptiStrong® is a branded protein hydrolysate derived from fava beans. A randomized study examined daily supplementation alongside resistance training. It is an addition to a routine that includes exercise, adequate dietary protein, and recovery; study outcomes are not a guarantee of individual strength or muscle gains.
Who it's for

• Adults who lift or train and want to support strength, endurance and recovery between sessions*
• Anyone working to hold on to lean muscle during a cut or a break from training*
• People who stack single ingredients such as protein, creatine or a pre-workout and want a clean addition
