An evidence-based formulation designed to increase free testosterone levels and support muscle strength and recovery. The active ingredient in TestoRestore has been shown to increase free testosterone and Insulin Like Growth Factor-1 (IGF-1), in a Placebo-controlled clinical trial, in healthy men. IGF-1 and testosterone support muscle function and physical performance. Exercise and excess perspiration increases the demand for zinc and magnesium, which are involved in muscle repair and recovery. Through providing these nutrients, TestoRestore may support muscle strength and enhanced recovery from exercise. Zinc plays a role in androgen metabolism and interaction with steroid receptors. It is essential for the regulation of cellular growth and tissue repair. Magnesium supports energy production, normal neuromuscular function and may assist with sleep quality.
