I can't smell this fragrance chemical - hardly at all.
But I notice when I apply this as a cover (using Molecule 01) to stinky mones, I no longer smell the stinky mones, either.
I wonder if this is the case for everyone - that it effectively hides mone stank. I know people's noses behave weirdly with it.
Allegedly this chemical helps will silage, too.
I had purchased my Iso-E a while back and, like you, can't smell it. Perhaps I can smell it a little but it's very, very subtle. Someone mentioned a long time ago that it can act as a defuser with certain mones but I only tried it a couple of times as I really didn't notice much difference.
To my nose it doesn't hide the smell of mones. It's easy to become nose-blind to iso e in higher concentrations, if you can't smell it try diluting it to 5% or less and then spraying it on your wrist or lower torso.
