Well, this was a really entertaining story, very well written and has barefoot giantesses, so it goes straight to my "awesome stories" folder :)

But I had to make a huge effort and (even if you used real places, real sport events and real people's names) try to not take it too seriously haha ^_^

It wouldn't be possible to start with, I think. Not only because of the (sadly) restricting laws of nature, but because of the Olympics' laws  xD http://www.thesportjournal.org/article/lausanne-declaration-doping-sport -point 2- As erotic and amusing as a growth ray is, it'd still be an artifice capable of enhancing the athletes' performances, so they wouldn't allow it irl haha (I could be wrong, but I think that stands as the official definition of doping for the Olympics).

On a more personal point of view, as a sport player myself, I would be offended if I was told "Hey, thanks to those scientists over there you can win any championship you enter because we're giving you a huge unfair advantage over everyone else". I don't know how a pro (olympic, for that matter) player would feel about that. If they agreed to that, it could mean that they would use real doping substances if the rules allowed them to, IRL, which would speak volumes of their sportsmanship -or lack of-.

As you pointed out in the wrestling competition section, anyone would have won if they were given that advantage, making it really an empty victory (mho). The US Olympic Committee could have just used their untrained daughters, grand daughters, nieces... or even themselves... and the results would have been the same. Easy gold medal.

That said, I admit I am being extremely nitpicky. The story itself was very, very well written and it was indeed amusing and exciting :)
