Hi Neve,
This article might help you. Using Pheromones for Attraction and Bonding
I thought at one time that a change in my pheromone signature might be hard for my husband to handle. What I noticed did work for him was to apply my mixes several hours in advance giving my signature a chance to blend. If your target guy has not bonded to your pheromone signature I don’t think this would be an issue. I am not positive, but I think we can not completely change our signature, only enhance what is already there. Because no matter what we have applied, eventually the blending occurs.
I do not try to hide my pheromone changes any longer. All he knows is that I smell good, and he likes that. A lot. So in my opinion if you find a mix or product that works for you, I would say don’t over think or question it. Just enjoy it!
