Believe it or not, the best way to pack on lean muscle mass isnt by concentrating just on increasing muscle growth. You need a multitiered approach that includes 1) boosting the processes in muscle fibers that lead to more mass and 2) enhancing other physiological systems that can influence muscle hypertrophy.
To build more muscle, testosterone isnt the only concern—the immune and endocrine systems must be running at full efficiency. Keeping your thyroid gland in optimal health helps keep muscles growing because thyroid hormones are actually anabolic. As for your immune system, if its run down due to excessive stress from super-intense training or other daily stressors, your body wont spend energy on growth. Instead, itll focus on kicking up your immune system in an effort to fight off any foreign invaders that could be making you sick.
Taking a supplement stack that stimulates protein synthesis in muscle fibers (aka muscle growth) and enables the body to better deal with stress is a smart idea. This jump-starts the process of muscle growth and keeps it ramped up. The following three supplements, when taken together, do just that. Theyll help increase protein synthesis, strength and endurance, and defend against stress and fatigue.
