I say keep it to yourself. Only my workout bro/close friend knows and he juices too. I made the mistake with my ex-g/f of being honest about it, she didnt like it at all, so I told her I would stop...well i did for a couple weeks then I was like...Im not gonna let some girl keep me from reaching my dream. If she really loves me then she will accept me for who I am....Well after awhile she kept nagging me about it and ended up finding out...were not together now. And though maybe it was wrong to keep it from her, I didnt feel it was fair for her to not even to try an understand. So from now on...Ill be sticking to the "creatine/protein drinks/eating 6x a day" story.
