But if they are solely used to enhance muscle and develop reflexes they otherwise could not have gained I think that would be bad for sports.
don't think there's any PED that exists that causes someone to develop additional reflexes, from what I've read that's a myth
that's why I don't really mind PED use in baseball, taking a PED doesn't all of a sudden teach someone how to hit a baseball. Granted it helps them with power causing them to hit it farther (thus making games more exciting). They still gotta know and learn how to actually hit though, which still makes these guys great players.
Contact sports like MMA, Boxing, and the NFL I'm not a fan of PED use though, cause you can actually hurt somebody with all that extra strength and power.
