NPA is far more overt than Ammo IME - None would certainly be the primary component.
I had wondered about rone for the second main component as NPA seems to have a better respect/commanding aspect without so much of the none cockyness compared to either TUTH or IJ despite its overtness being somewhere between the two.
I haven’t worn NPA for fear of OD but I am 42 and get by great with 1 spray of Edge to shirt and 2 swipes SOE to neck.
I covered with 3 to 4 sprays of PLAY cologne.
The result, almost nonstop friendly , sexy, humourous, behavior from women exposed for the first 5 hrs or so then when I went out at night I had a guy stop his car in front of me and literally make me wait as if I was tailgating him which I was not .. he was also cursing. I don’t know if this was related to Edge as it has some properties which make men angry or if this was coincidence but such behavior hasn’t happened to me in a long while.
Lesson learned, if you’re going to be around guys primarily give edge npa a rest and don’t use it. If you’re mainly going to be around women go for it.
My only theory could be that the nol on SOE converted to none after many hours and what I experienced was an Edge/NPA OD.
I’m glad I applied to shirt… Now I can take off my shirt take a shower , and wear a new shirt with edge tommorrow.
My only concern is buildup of SOE… do you think too many days of SOE in a row would also cause NONE od as nol converts to none over time?
There’s a rumour going around saying NPA contained Meo Est and new version doesn’t that’s why it’s not working as good.
No rumour - Just someone asking about the possible presence of Meo-Est in every product under the sun.
I really can’t think of a phero less likely to contain Meo-Est than NPA! 
And I’m also highly unconvinced about all this about “New NPA” - Again, that seems to stem from someone looking at Lacroy’s recent branding and bottle revamp and simply jumping to the conclusion that the product “must” have changed as well. Which is not a given.
Also, I’ve now got three bottles of NPA on the go - the latest product (black cap/flat dropper) which arrived direct from Lacroy a few weeks ago, the intermediate - of about eighteen months ago (White cap/flat dropper) and a tiny bit left of the old stuff of around 3 years ago (White cap, recessed dropper) and I cannot find a blind bit of difference between them - no difference in colour, scent, strength, exactly the same feel and effectiveness in use and the breakdown stink just the same over the same timescale. Its still good, if a bit blunt/raw stuff! 
This is a rumor started on another pheromone forum. A member of that other forum claims that NPA has ANDROSTANdienone & Methoxytetraenol.
Only the manufacturer of NPA knows for sure what is in NPA but everyone agrees that the main component is -none.
It has come straight from the horses mouth that impi does contain meo est, so is it not possible that npa COULD contain it as well?
The sheer rawness and particular properties of NPA and its sister products are against it for me. Lacroy seem to look to A1 to provide the comfort/closeness aspect in their core range, whilst Impi, and Chikara are very different products to Edge, NPA and Liquid Trust - Which befits lines manufactured for another company with different and more social priorities.
Man I don’t like being rude but I messaged Lacroy about NPA and asked if it contained Est, the reply was No it doesn’t, I then messaged the same person asking if NPA contains Meo Est, I still have not got a reply and it’s been more than 2 weeks.
It was said that Impi contains some estratetraene …
but honestly this could mean a lot .. and … what about the Maiworm studies .

What is NPA?
Its a competitor’s product - an overt/blunt instrument sexual, sold as a concentrate you either dilute with cologne, or in more limited environments (clubs etc) you can get away with a few dabs direct from the dropper - but its prone to breakdown/stink that way.
Lots of threads here discussing its use and dilution already.
Wow thanks for the info. I’ll do a search. I will also update my initial post with some observations so far.
As to the hypothesis that NPA contains A-1, I’d guess no way.
I’m pretty sensitive to A-1 depression and I get none of that with NPA - and I can dose it pretty heavy, with the right woman.
My much younger Asian new GF seems to respond to TUTH a bit better than to NPA although she is positive to NPA too. I’m going to test this impression later.
I’ve never thought there was much A1 in NPA but I do get its stink in broken-down NPA - and like A1, when NPA starts to turn to stink, it goes pretty quickly, so I’d guess the dose is pretty small and whatever else is in the mix offsets it quite nicely.
A couple of months ago, I sent a message through LaCroy’s contact us form on their website asking if NPA contained Meo Est. They did not get back to me.
Doesn’t mean much. LOTS of companies ignore that. A call might be in order.
LeCroy is under no obligation to disclose the ingredients of NPA or any other of their formulations. Trade secrets can be lawful private property.
If you can claim personal damage then you might be able to claim discovery as part of your civil lawsuit against them.
FYI I got my NPA, and added it to Nautica 4.5:.5
So far not really much effects. OD? I can smell it faintly, but it doesn’t smell bad. My Filipino maids, CAN smell it and they say it stinks
I put it in a To-Go bottle so I can reapply at work So far nothing really doing. I wear it around the wife and I’m sure to kiss her and hug her so she gets a good whiff. So far nada…
4.5/0.5 is a bit low for dilution - 0.8-1.2ml NPA into 5ml is maybe a better range for you at 39. I mostly dilute it at 1ml NPA plus 4ml cologne but sometimes I’ll do higher for high-impact situations.
And I wouldn’t be wearing this to work - which is the most un-NPA friendly environment possible!
I see. I was trying to ease my way in. I think I’ll just balls to the wall, 3.5:1.5!!!
Reason for trying at work is that I want to see a reaction.
I work in Asia so my assumption was .5 was a safe bet.
