The spray is very, very thin--about the viscosity of water-based perfume. There's no residue once on the skin, and it soaks in very easily. The liquid doesn't drip down the skin once sprayed.
It is recommended not to ingest the spray. As for the smell, out of the bottle, it doesn't smell like anything. After it was on the skin for some time (a few hours), it started to smell very... odd, like perspiration. These pheromones are supposed to work with your body and come up with what is most appealing for you. Apparently it doesn't come up with anything appealing for some.
The product lasted until the decision to take a shower--after about 6 hours (and after it was commented, "what's that smell?"). It washes off easily with just simple soap and water. As indicated earlier, it absorbs into the skin very easily.
The only positive thing to say about it is that it's in a very pretty tube, with very pretty packaging.
Your mileage may vary, I hope it does!
System JO's Pheromone Spray for Women comes in a lovely clear and light purple tube, with the product visible from every angle. On the back is information on what pheromones are, why you need this product, directions, and the standard warnings.
The tube itself is a nice light bronze color and has nothing on it but a silver "JO". It's very discreet, and can be hidden in my palm. The spraying mechanism is similar to that of a perfume sprayer, delivering a fine mist.
In all honesty, I'm rather skeptical of these fake pheromones, and this just confirms my hesitation. It made me smell kind of bad, like I had been at the gym all day and hadn't taken a shower.
In the name of science, I went out to a club with generous portions of this on and... well, nothing more than the usual drunk and disorderly trying to pick me up.
