I’m just gonna assume it works the same way as when alphas leave theirs pheromones on an object and it sticks to it for a long time. But since it’s basically his pheromones in liquid form I’m pretty sure that’s the case. Better than the other option of funky spunk. ( ̄∇ ̄")
I just have one question. If those vials are 2 months old, don't they stink?
