Where in the world did you get this from?
The laws in the bible often contradict the laws of man.
You can't obey both of them in such a case.
The bible makes it clear that you should obey IT and not the laws of man.
Exodus 20:3 states you should have no other "gods" before the one god. Meaning worship no one and nothing. Obey him and just him.
Isaiah 33:22 states God is the "lawgiver".
The bible makes it clear that when the "laws of man" interfere with the laws of God you should obey the "laws of God".
Insinuating that since Anabolic steroids are illegal under man's law they are illegal under "gods law" according to the Bible doesn't make any sense.
That would also mean that if sex before marrage is legal under mans law it's legal under "gods law" according to the bible. Or worshiping other Gods or working on sunday or disrespecting your parents..ect..ect.
