My friends call me "Menz"
so i wrote to 420 science while i was waiting for replies from FC members... they said for my 12oz water bottle all i needed was 12 drops. one drop per ounce is what they said. i already did the 36 drops in this water bottle before i got their answer, and i still have plenty left in my bottle. just thought i would let you all know what they said, should you want to try and conserve your product longer
