Is Musk Therapy more floral or more musky?

Musk dominates. The floral and fruity notes sit on top as a lift, and the amber base softens the drydown. Expect a clean musk scent, not a big floral bouquet.

How long does an extrait like this last?

Extrait de parfum is the most concentrated form, so it typically lasts many hours on skin. Musk notes in particular cling close and linger quietly rather than projecting far.

Yes. Initio lists it as unisex, and the soft musk-amber profile is not strongly gendered either way.

What is a vial sample good for?

Testing on your own skin over a few wears. Musk reacts to body chemistry, so a vial tells you more about how it wears on you than a paper strip does.

How should I apply it?

Dab or spray onto pulse points such as wrists and neck. With a concentrated extrait, one or two small applications is enough; more does not add much projection.
