Did you realize that dosing hemp products is a bit challenging?  It's not just you.  500 mg, 3000 mg, 30 ml, 60 ml, or 1 dropperful or 1 drop.... Don't worry.  I created the Find out my Hemp Dosing page for you.  It is FREE. All you have to do is plugging in the number of mg on the bottle, the number of total ml of the bottle, what ml you are taking per dose, and how many times a day you are taking.  You'll find out how much current dose and how long the bottle last.  Also it's great to switch back and forth between different brands or strengths.
