I have been using pheromones for quite a while. For the most part, if i am wearing a mix ie: SS4M or Wanted Man, I stick with that mix only. If you mix mixes, you just end up with a big muddled mess. Or in the case of guy's sex mixes, you run the risk of a 'none OD. I will sometimes throw in some b'nols on top of certain hard mixes (not sold nere) to soften them a little. You still come across strong, but more friendly as opposed to predatory. I really do not do that with the mixes mara sells here.
