You mention to your friends that you'd like to get bigger too, and you start winking to let them know that you're "down." You go with them to the gym, and you quickly spot the only personal trainer wearing a trenchcoat in the gym. You turn your hat around and bend down to tie your shoes. This is how you ask for a "fat sack of Human Growth Hormone" if you're "down."
The trainer nods and motions to the restroom directly behind him.
What do you do?
