This is a study on testosterone. The C.D.C is standardizing testing procedures and trying to get labs on the same page. This study says that there's no real legitimate way to categorize mens low test because labs are testing amd using different methods. Thought this would be a good read as well as informative. My buddy Rob was doing some research and I asked him to pass this along to me so I could share here at Meso. Hope you all get as much out of this as I have.
