I received this as a gift in my recent order (thank you!) but have no idea what its purpose is! Info on the forums about this is limited so if you have some feedback I’d really appreciate it 
MX343 is part of the P78 test pack for women and only myself and I think sillykitty on the forum have the whole test pack which is 341-346.
It is very new and a few members sometimes get one from either MX341 to MX346 to test out so you won’t get many posts on it.
I have tested MX341 and reported, silly has tested both MX341 & MX342.
Recently I was asked the same question about MX344 and she tested it out and had great results which she posted on the forum.
It is not a good idea to read and try to determine what something does from reading other member’s threads/posts because it will affect your findings.
They are called experimental mixes because we are not 100% sure what they do and want your feedback on it.
Testing blindly is the best way. This will allow you to get your own results and not miss any hits while looking for someone else findings.
Make sense? 
Yes thanks so much for the response. How exciting that I have a test product! I’ll definitely post results and findings as I discover them. I decided to try a spritz of it last night just for kicks. I had to stay up late to finish a paper… the scent is really nice for one thing, kind of like a vanilla fruity musk or something. I couldn’t stop smelling myself! I don’t know if I noticed anything different than usual other than other than once I put it on I was less tired and more focused than I typically am at night. Really helpful for procrastinating!
