Skeletal muscle protein balance regulation Skeletal muscle mass depends on the rates of protein synthesis and degradation

Once produced, TMA is absorbed into the bloodstream and transported to the liver, where it undergoes further oxidation to form TMAO via the enzyme FMO-3 [23, 25]

Glycine propionyl-L-carnitine produces enhanced anaerobic work capacity with reduced lactate accumulation in resistance trained males

Though this theory is promising, more research is needed to confirm it

Research also suggests that L-carnitine may help facilitate increased uptake of testosterone by promoting the expression of androgen (testosterone) receptors in skeletal muscle tissue (1 Kraemer)
