I'm not sure I would characterize the fragrance as energizing as much as enervating. Between what smells like anise and a very rich datura aroma, I find the perfume evocative of something very carnal and reptile-brained. I love it.
I got this bottle after buying the zen and loving it. (I haven't been able to find a bottle of that lately, and I really miss it.) I think it's really nice and fresh. On me, it picks up notes of powder that I really quite like.
