Is taking human growth hormone while growing up cheating if u box now?

No. There is no medical test in sports to know that u took HGH. the only way they can do that if they take a sample of your bone marrow. maybe they will come up with a test in a few years

It's a debate I was thinking about when hearing Lionel Messi was put on HGH growing up. Without it, would he have made it to Pro Soccer? And who knows how many people could be using it right now, even as adults. But to your point: It is deemed Medical treatment. Wonder if those that need Testosterone shots as well are able to compete...not sure. Maybe if it is in what is noted within "legal/normal" limits.
