There are so many scams/so much hype out there about pheromones and little real understanding/knowledge of how they actually work. It’s only natural to be skeptical when exposed to things that are questionable/unfamiliar and the only way to dispel that is to try them out for yourself. We’re all different and pheromones are subjective. A product that works well for me may not necessarily work the same way for you. So, your mileage may vary accordingly.
When you first start out using pheromones if you just spray them all on at once, you’ll never be able to clearly determine which one does what. There’s a learning curve to pheromones. That’s why it’s best to start out on the right foot by trying each product separately and finding your “sweet spot”, for that one*,* before attempting to combine them. It does take a little time/patience to figure it out but it’s worth the effort to do it right or you’ll never really be able to pin it down. Once you do that, then you’ll be better able to combine pheromones to achieve the effects you’re after.

Also, if you haven’t yet, do yourself a favor and take a stroll through the stickies at the top of each forum. Alot of newbie questions are already answered there. Yes, you can find threads/posts on the putatives (P’s), including P86, and the MX’s by using the search function! 
Hang in there, Beauty, do your homework and you’ll be on your way before you know it!
