Really it is no ones concern . If you are on juice or if they are.
I have lifted In many gyms over the years. People talk if you do not want the gym to know you are on then you can never tell anyone PERIOD. little ears are all over the gym that hear stuff and repeat it.
for example you might say " i did a dbol cycle 5 yrs ago "
little fag boys doing abs over heard you and runs to the locker room and tells his friends" i knew it he used roids"
Besides usually the juicers are looking for is a good deal on gear.
If the guy you ask is on juice,chances are he will try to sell you some
if you repley you get it cheaper then he will prob wanting you to hook him up.
its really a bad situation ether way. Just go to the gym and lift.
besides you did not get your hand out from the YMCA instructor on how to spot a juicer ?
