Frontiers Androgen Receptor Signaling and Metabolic and Cellular Plasticity During Progression to Castration Resistant Prostate Cancer L Carnitine Linus Pauling Institute Oregon State University Androgen receptor density plays a meaningful role in muscle anabolism because it determines how strongly a muscle fiber responds to androgen signaling. Gabriel Alizaidy, MD, MS TRT Doctors, Vigorous Steve and MPMD recommend oral L Carnitine Tartrate supplementation for increasing androgen receptors count or sensitivity. I remember Eric Trexler disagreeing with this. Have you changed your mind? Why are
