hey bro be sure not to show your probation officer your size at all! They CAN and WILL test you for juice if they even suspect your on any steroids. However they can only easily test for oral steroids which isnt that expensive for them to do, however its way to much money to test you for injectable like testosterone!
I had a friend of mine in New Jersey on probation who they tested for steroids and they found dianabol in his system and locked him right back up , he posted bail got a hearing and was able to prove to the judge lucky for him that he was taking a legaly sold supplement from GNC that was tainted with real steroids and he had the paper work and the lawsuit papers to prove it, however he wasnt realy taking thelegal shit it just so happened that around that time theri were a few underhanded companys like "Hot Stuff" whos products realy contained oral steroids in them and he was able to say he was taking that and got off!
Also if your asking why he was tested for steroids during his probation it was because he was busted with steroids and was jacked out of his little 5 foot 1 inch and 270lbs mind and didnt know the judge ordered his p.o to test him regulary for gear and this was like ten or so years ago so becarful and DO NOT EVER go into probation showing of ur muscle, look fat in bulky cloths or meak as possible!
