The bottle contained 30ml and it lasted about a month. On the label it says a full dropper is 5mg and I did 10mg every morning.

My bottle is measured in ml, so I'm trying to count the drops.
Looks like some math is in order. I recommend starting with 1mg and working your way up to 10mg. Do you have a micro gram scale?
No, just grams.
What differences did you notice after finishing the bottle? I've been taking it every day for a week at a low dose (20 mgs) and don't really know what to look for.
