Golovkin is 173-175 on fight night. He's been weighed in. We have posted these weights before. And links to the weigh ins. You are pretty slow.
That said, kudos for doing the best you could with a crap hand. The hair follicle test is unreliable, and extremely unreliable with reds and blondes.
The values detected from test to test can be unreliable, but that does not equate to no detection. While the possibility exists that a test may not detect anthing, its my understanding that it likely will. For any fighter to take that risk says something about the honesty of said fighter.
