Ever tried to use supplements for you muscle built? Examples would be testosterone, which are common for weight lifters and muscle builders. sample brands would also be Syntheroid. Have you ever think of syntheroid side effects? My suggestion is to always consult your physician first because you may never know side effects of these drugs if never inquired about it. For me, natural method is still the best method. It would be safe to just stay natural than experienced symptoms that would make you regret taking one.
