top or bottom of my wrist? or both?

Hi Snorida45x,
usually a good answer could be “spray the Pheros where do you think that are more affective”, for example, the places listed by Jamesbonded are the best ones (do what Jamesboded say as he’s a Phero-Lord!). The answer about the pulse points is because the warmth would help the Pheros diffusion.

See ya
