This has to have been covered already… If so, please link me to it.
Southpark has an Episode about this. And I have heard it on other videos before. But never seen any research papers or science videos on it.
So is there any research on the matter at all? Or is it just a nice insult to throw at people?
Again… probably been covered, if so, just link me

A possible real answer:
Steroids (as taken by bodybuilders to increase muscle growth) are known to have a couple of side effects:
Possibly this fact has been interpreted as a general principle?
Abusing steroids also leads to shrunken testicles.
For whatever reason, this only results in folks consuming additional copper and zinc way above the RDA to overcompensate for their “loss”.
And Acme levels of acne.
Actually steroids shrink the testicles, not the penis. Steroids can make the penis larger in fact.
Southpark in no way resembles a reliable source of information about the real world. The only good thing that can be said about it, in this regard, is that it in o way even pretends to be a reliable source of information about the real world.
