You guys are likely young men.  Let me give you some insight.  I (the govt) can find out anything I want pretty quickly if its needed.  Your charge cards where you were yesterday and today. Property records what you own and where.  SSA gets quarterly payments from your current employer. Phone records, etc. etc.

If you think you going to hide its not going to happen unless you get completely off the grid like the Unabomber

But you are safe because their are 330 million of us in the USA. Now while you watch a lot of tv and are pretty sure the world revolves around you it doesn’t.

Do you think an enforcement office is going to use its limited resources to investigate some kid taking steroids?

There are 50 fentanyl and meth operations that need to be shut down and our govt office only has staff to investigate 4 of them.

You and your bottles of testosterone just aren’t even on the radar screen. That’s whats going on inside.

If USPS picks it up they will just keep it and send you a letter saying you can’t get it thru the mail. 1 in 100 times. Don’t sweat it and don’t be overly fearful.
