Is mx390 the new version of mx297 and is it possible to od on it?
Its just MX297 with a different smell 
I have tried till 5 sprays of 297 without any OD effects.
However high doses of 297 or 390 without other sensual steering mones may land you in the ‘best friends’ category pretty fast 
And by steering mones, you mean -none right?
What were your experiences with that?
No one knows with absolute certainty which molecules are in these MX’s. However, most users have found adding products like AMMO/A314/Putatives/TUTH in some of the mixes steers them in a certain direction. You won’t know until you try it yourself, but go with the sprays by itself before you start changing things around.
Why is this?
I thought it was pretty much a standalone worthy product. Just interested as I’ll be testing soon.
The MX’s are pre-made mixes of different mones generally. So these will all have several products in them already and are meant to be standalone mixes. The Putatives are just single standalone mones to test and report on. 
They are just that, everyone likes to add more stuff to things to see how much more they can modify it or tailor it.
But in reality, a couple of sprays would do the job.
mx297 is one of the best mixes ever. great by itself but also blends well with many other pheros. i just ordered mx390. can t wait to try out the new scent and compair it to the old.
does anyone happen to know what scent mx297 batch #617 happens to be? I have it and find it kind of interesting… is it Akuto?
sorry for hijacking
Of course it´s Akuto
you´re right guessing ..
I´ve been complimented several times on the scent and love this mix to death !

I really like Akuto, very daring! As a fragrance enthusiast it reminds me of a fragrance but I can’t quite remember which one. It smells like a Serge Lutens…
