The LC-MS/MS method for the simultaneous measurement of circulating total GDF-8 and GDF-11 demonstrates the characteristics of a valid assay. Testosterone treatment increased GDF-8 levels, but not GDF-11. Increase in GDF-8 levels by testosterone treatment which increased muscle mass, suggests that GDF-8 acts as a chalone to restrain muscle growth.
