Entering USA with Clomid and Viagra

Hi,
I am finishing my cycle on the 20th of january and thinking to fly out to USA on the 23rd. I am running Test Prop, So my PCT will need to be started straight away.
I just wanted to know the rules and law on bringing my PCT with me? Illegal? The viagra is if I score :slight_smile:
Can anyone post the actual Law regarding this?
