I don't know for sure yet but the bottle is generous and the amount you use is miniscule hence I expect it should last at least a few months.

I use it once a day and I get about 7-8 month's worth of time with it. I also managed to spill some, so it would probably be more like 9 or 10 if I hadn't done that.

I've been using my 7ml sample bottle twice a day for almost four weeks, and I've gone through less than 3ml. The full-sized bottle I ordered is 30ml, so I'd say at the same rate of usage, it should last 6 months, easily - but probably closer to 10. Keep in mind you only need a tiny amount!
