Not sure if I am getting this right but did you sniff out of the same vial all of these times and then the bottle you ordered smelled differently or? Or was it just different experiences with sniffing PP from the same vial?
If it's the prior, I believe there are two formulations of this due to my own experience with PP and the difference with the bottles. If you tried the white bottle with the white cap..I believe that's the one with more gardenia. The one that's out now-I think- is a white bottle with a dark purple cap and I got less gardenia from it and more jasmine. I actually smelled the later first and kinda liked it..then ordered a white bottle with white cap and I got more gardenia from it and returned it. Did the one you try recently come from a bottle with a dark purple cap? Sometimes when there is a bottle or package change, that can mean reformulation from what I have heard.
So to clarify I got more gardenia from this bottle, which I believe is an older formulation:
And I got less gardenia from this one, the bottle it currently is sold in:
Not sure if that's the case but they smelled different to me, I think.
