Difference in sillage/longevity between actual bottles and sample sprays?

Hi guys, just joined here so forgive me if this question has been answered before, but quick google search didn't return anything.

Anyways, I just recently got into fragrance. I'm 21 in college and currently, I only have JPG Le Male, and L'eau D'issey pour homme by Issey Miyake.

I have normal skin (not too oily and not too dry) and I get decent longevity from those two frags. 8 -10 hours easy for Le Male, and 7-9 hours for Issey Miyake.

Couple days ago, I got a sample sprayer(two inch vial) of Chanel Allure Homme from the Bay (which is a very well-known department store in Canada) and unfortunately, I rarely even reach the 4 hours mark(I do three sprays on side of neck and wrist). Around three hours mark, I would literally have to put my nose right at the wrist to smell it. I get decent sillage for the 1/2 - 1 hr mark, and wears pretty close afterwards.

But online reviews tell me that Allure Homme is supposed to have excellent longevity, around 7+ hours.

I was wondering if I'm getting poor longevity because it's from a sample sprayer and not an actual bottle. I get expected longevity with Le Male and L'eau D'issey.

I really like the Allure homme, but 4 hours is just lackluster in my opinion.

So I'm asking if any masters out there knows if there is actually a difference between actual bottle sprays and sample vial sprays.

PS: I would go to a store and try the actual tester of Allure homme, but the ones near me only has tester for Allure sport and Edition Blanche.

Thanks and sorry for the long post!

Thanks for the tips guys!

Yes I thought I was just getting used to the scent that I don't notice them anymore, but I can still smell them fine on the sprayer itself.

And I do get usual longevity as other ppl with Le Male and l'eau d'issey, just not Allure, or it could very well be fatigue as you've mentioned, especially because I used to put the sprayer under my nose a lot recently; the scent is just very, very pleasant to me.

hmm

ok this might seem like a stupid question but i gotta ask,

do the amount sprayed from actual bottle differ from the sample sprayer?
in other words, do actual bottle sprayer give out more juice per spray compared to those sample vials?

I read 3/4 spray is normal for allure, but since I used sample, I should have sprayed more?
Thanks!

well it turns out the sample sprayer was the culprit!
yesterday, I had the chance to try the actual bottle and could still smell it after 10 hours, although i had to put my nose really close to the skin.

actually, i found out that allure homme, to me, wears really close to the skin after 3 or 4 hours.
i don't know if it's normal or not but i really enjoy the scent.
