Hey
folks,
I had ordered some NPA some time ago and only used it maybe 5 times. However, I just found that bottle
in my bathroom closet and found it to be almost empty! Could it be that this stuff evaporates out of the closed
bottle? Maybe the cap doesn't really close this stuff air-tight??? Anyone experienced something similar?

bubblebob,
I'm going to guess that either somebody messed with your NPA, or that the
cap wasn't screwed on tightly, or that the reducer cap (dropper thingy) had been dislodged or discarded, because
those are some of the most reliable bottles that I've ever come across in my years of phero use.
The last
time that I actually bought any NPA (http://love-scent.com/product_info.php?ref=66&products_id=21) was in
early 2004. I remember it was right when NPA switched from cobalt blue to the current amber colored bottle.
Bruce
was running his "Whacky Wednesday" specials, and I ended up with 5 or 6 bottles of the stuff.
I just checked and
I'm down to 1 1/2 bottles at this point, and both the unopened bottle and the partially used one seem to have
exactly the amount in them that I was expecting to see.
Additionally, I've recycled quite a few of those
bottles, carrying mixtures in pockets and knapsacks over the years, and I've never once seen any signs of leakage
or evaporation from them.
I would be willing to bet that the bottle itself wasn't at fault.

I indeed removed the
dropper-thingy, because I measure my dabs without it... And it kind of goes on my nerves to remove and install that
thingy everytime I use NPA. Maybe I should just use another bottle or change to using drops instead of
dabs...

I just bought NPA.. What
"dabber" thing are u referring to?? when i open it.. I see a little hole, and an arrow.. the cap has a pointy thing
in the middle.. is that used to calculate "dab" cuz i cant seem to get any from it.. i just kinda put my finger on
top of the bottle and tilt it to get some on my finger... any advice??

My NPA seems to last forever. No
evaporation I can see. However if the alcohol did evaporate, the androstenone would merely be more concentrated.
Maybe your little brother or roomies been dippin' into yo stock...

hmm interesting thread. How
about the evaporation/duration rate on human skin? How far can 1 drop go in your past experiences?:think:
btw.
I dabed once directly onto my wrist, and then one split on each side of my neck today. I feel like I may be
overdoing it. I wish I could smell the damn stuff. lol..

The alcohol carrier evaporates
within 30 seconds or so. The smell of none can last for days. I can still smell it after soaping the area and
showering. When applied to clothing it lasts for weeks.
