What is you favorite mone mx for progressing a relationship with sexual undertones?
MX or ExperiMone
MX’s are mixes
ExperiMones are single molecules
MXs of Experimones either pre-mix or done using putatives on your skin. The MXs are under experimone in the store along with the putatives. sorry for the confusion. I’m also assuming MX stands for mix. Correct me if I am wrong.
I resend the last statement, they are under advanced users. I am looking for good combos to test on my own. 
You may have let yourself open for quite a thread here! 
There are a great deal of “favourite” combinations that many users have used to progress relationships.
It might be better to look at the pheros that work best for you, then search out the variations that other users have made to suit their individual situation/body chemistry>
You are the artist, your skin is the canvas. Go through Journals of some of the members here and you’ll see some of their combos.
Smellymen, jesse, maiden, steve, jayarea, boogie, josiew, thegentleman are just a few you can read on their testing.
If you notice as well, there are a lot of differences, why? Because of personalities, goals, and body chem that these guys have which make their combos unique.
I suggest testing them out for yourself and then starting to build what works for you.
