Tell them your holding it for a friend most mature answer available. Not srs. Let em know you appreciate their concern and let them know you've done alot of homework and are not abusing your gear like alot of idiots out their and are taking alot of safety precautions for your health. Then answer any questions they have, just them knowing your still in a right state of mind and not 'roid raging' or acting like the stereotype of what someone on roids what act like gives them peace of mind. Or back to the bribing a friend to says its his =P
