ive read threads and explanations on how to find ones specific sweet spot. it seems like it takes a while, but my question is…where do you spray to begin with? lets say you start out with 1 spray for a few days. do you spray on your chest? neck? hair? wrist? wrist and then rubbing it on your other wrist? wrists and then rubbing it on your neck? as you can see, theres so many different areas you can spray the pheromone. so do you just take it one area at a time or what?
My understanding is that the ‘sweet spot’ is the amount of mones used as opposed to the location applied? Perhaps its a combination of both, im new to this also 
One thing i did notice was that with the spray on mones, the distance you held the atomizer away from yourself while spraying played a factor with me. 60cm away, wider field less concentrated spot, 30cm narrow field, with more concentration on that area.
I found with me it was better to have a wider field and apply to a wider surface area as opposed isolation one location, but hey thats just me!
The area you spray your mones is kind of up to you. The neck, chest, writs, hair have the best diffusion rates from my experience., but there are some mones you do not want to put in your hair because they are very sticky and last quite a long time.(and example of this would be IJ)
I would start out with you neck, this has good diffusion for people who are close to you. If you want to effect other people more than yourself I would go with the wrists. I personally talk with my hands and I can tell a big difference from wearing them on my neck.
