I know that different medicines are used up by the body or rendered inert and this time it takes for the medicine to be gone is called a “half life”. I is measured to determine how long the effect of the medicine is in the body.

Is there something similar for [pheromones](https://pheromonelabs.com/)?

If you spray on a product mix… how longt till it is half gone?

How long till it is all dispersed and gone?

I am not talking about the scent or fragrance… just the pheromones

It’s not really possible to say as there are way to many factors that affects the “half life” eg the environment your in, application points, how much you sweat , the type of phero , the medium the phero is dissolved in etc

As a rough estimate most phero’s last for 4-6 hours in normal room temp. Some (eg none, TAF & cops) last longer, others burn off quicker (eg P79, TAA)
