Truth is. Customs just doesn't care about your 200 dolllars worth of test and dbol. They dont have the time or the money to pursue all the small time punks who just buy for themselves or their buddies.
Steroids just don't cause that many issues in our society, they have better things to worry about. We dont have enough police officers as it is to be pulling them off of real cases and going after joe college student who wants to be the biggest bro on campus just isnt doable.
Im a big fan of the police, they keep all my nice shiny things in my possession. Dont give them a reason to believe that youre trying to cause problems and they will usually leave you alone to shoot poorly manufactured Chinese steroids into your body in the comfort of your own home.
When they accidently stumble upon your stuff during the process of looking for real drugs and other nefarious shit, as long as its clear youre no dealer, and are just a punk you wants bigger arms, they take your stuff and send you a "finger wag" letter.
