I propose a project.
One of you steroid users go to the pet store and get a few mice. They're cheap. Then, stick them with whatever's left in your needle after you stick yourself. Test will suffice, but hgh or insulin would be even better.
Take a before/after pic of the mouse. Show us all how he grows. When you're done with this experiment, kill him in some hilarious manner and post those pics too. Thanks in advance.
