B-12 doesn't color your urine yellow, B-2 does that.

Color isn't important unless they are using an instant test. You should be using a sports drink to help with specific gravity and follow the recommended volume.
FakeBoobsRule Reviewed by FakeBoobsRule on . What's my best bet? I just smoked a joint yesterday, and today i learned that i may have to take a drug test. (lucky me) I'm 5 foot 11, and weigh about 155. I followed the dilution tips, and took a creatine supplement. I have drank about 10 bottles of water today, and my pee is a clear white. I just took a B12 timed release. What are my chances? Rating: 5
