Death perfume "Eau De Death"

A Nebraska-based chemist claims by mixing a combination of three disgusting smells, she can create 'Eau De Death’ that mimics the smell of rotting human flesh.
The three compounds are putrescine, cadaverine and Methanethiol.

While putrescine and cadaverine are emitted by the body in the early stages of decay, Methanethiol smells like rotting eggs.

One could wear it while casually waiting for the zombie apocalypse so as not to attract the attention of a roaming group of zombies.

The 'death perfume' is incredibly stinky in very low quantities.
