USPlabs Modern BCAA™ is developed under these strict rules:

    BCAA Ratio formulation with mTOR activation in mind
    Ultra-Micronized
    Mix Clean
    No Artificial Colors
    Natural, refreshing taste
    No L-Glutamine

A common issue with BCAA absorption is that all three of the BCAAs – leucine, isoleucine and valine – compete for the same transport systems, and as a result, the presence of high concentrations of the other two BCAAs may lower intracellular levels of leucine.


USP Labs use the perfect 8-1-1 ratio for ultimate results.

By increasing the "normal" ratio of leucine to the other two branched chain amino acids they ensure:

Double & mega dosing are unnecessary, as we have already doubled the component that is primarily responsible for the protein turnover and synthesis increases we see with BCAAs.

Competitive metabolism between the amino acids will not lower leucine levels to the point that it is unable to regulate mTOR.
