Yes I know but, this has been puzzling me for some time.

I have a range of technical T shirts, the wicking ones.

Quality varies. I have a couple of nice quality ones I use for races or longer runs, and I have some mid price and some of the freebies picked up at races.

After a while, I can detect the whiff of BO within a minute of putting them on, so I get shut. I'm sure most running blokes are in the same boat.
It's as if the body heat activates the remnants of some microbes.
Some wash well and have been going for years and show no adverse signs.

The puzzle - I have about 3 of them that release the smell of honey. I put one on today, a Darwen Gala Fell race freebie.
Within 2-3 minutes of setting off, that slight hint of honey smell started playing around my nostrils.

Am I alone?

I suspect I am
