Sheffrin Men’s Health believes: Aging men can dramatically improve their quality of life with proper testosterone therapy, optimized for each individual and administered properly.The benefits of testosterone therapy are significantly improved when therapy is complemented by proper nutrition and moderate aerobic and anaerobic fitness.Men who have lead active lifestyles are likely to notice a dramatic decrease in stamina, performance, body composition, focus and well-being as they age. We believe that by the benefits of modern medicine, men do not have to settle for a lower quality of life because of natural decrease in testosterone level.Only proper testing can ensure that decreased lifestyle levels sensed by aging men could in fact be attributable to decreased testosterone levels.
