Twinlab L-Arginine by Twinlab
L-Arginine may promote muscle-building activity in the body by increasing levels of anabolic (growth-promoting) hormones such as insulin and growth hormone! Arginine is necessary for the execution of many physiological processes. These physiological processes include hormone secretion, an increase in growth hormone output, the removal of toxic waste products from the body, and immune system defenses.
Because Arginine is a precursor of nitric oxide [which is responsible for vasodiolation 3] it is often used for treating conditions such as chest cramping [angina], high blood pressure, heart disease, and sexual dysfunction. Arginine is also used in the treatment of male and female infertility.
