I just got my bloodwork done, as I do every six months just to see how everything's going. I'm 22 all natural 5'8 175 lbs 7-8%. My testosterone has dropped by 200ng/dl since 6 months ago. And I have trained cosistantly since, 6 days a week lifting. Not sure if it's because I drank alcohol a couple days prior even though it was minimal or it's because my testosterone is already starting to decline. Because it's very hard to make gains this past year.
