How long does A314 last?

three drops a day

You get 23.8mcg (micrograms) of 9 human pheromones in each drop of Alpha A314. There are 6,667 micrograms of pheromones total per 10ml bottle’

So 6,667mcg/23.8mcg is ~280 drops per 10ml bottle

That’s a lot of A314. Three drops and people tend to scurry away and I end up drinking alone after work… One drop normally does me well for the entire day.

Yes - three drops can be too much for a lot of people. Test carefully from one drop upwards and in a variety of situations till you find your best dose/dose range.
