I watched an episode of House MD before where two kids were admitted because they have an oversupply of testosterone in their bodies – the girls gets crysts everywhere, menstruates early while the boy goes into rage over the littlest things. One would think they had testosterone booster based on the results of their tests. It turns out it was environmental exposure as their father uses enhancement creams which he just took from a store, not checking if it was FDA-approved. He leaked testosterone in his skin!
