I think it's just a silly question created in a weak attempt to get someone on here to say it's ok (better) for a 20 yr. old to use AAS.
It's silly because both are bad for your health.
It's like asking,
What's worse, smoking 4 packs of cigs a day, or drinking a gallon of kerosene?
One is probably worse than the other, but BOTH are bad for you,
I wouldn't pick either out of drinking kerosene or outrageous smoking habits.
