I think that M-Test would work very well for you. As we all age, our testosterone levels typically get lower and even if not clinically below normal, the lower they are, the less like our old selves we feel and perform. By M-Test helping raise your natural test levels, I would expect (and I experience myself) improved mood, energy, libido, and better performance in the gym. I do think it would also help you get leaner as well.
