This is the first time I ever ordered pheromones' oil. (Or sprays of any kind). Oh, and to note, when you apply it, it comes out red, but you have to rub the oil in anyways, but it disappears. It's no biggy for me. OMGosh, this stuff is killer!!!! I love ❤️ how you can smell the changes in the scents. I guess with my mood changes and chemical changes in my body, this changes. For me, I have smelled it pretty strong. I really liked it! The other scents have been lighter, all so different. I do order a lot of different things from Amazon and fail to say that all my order have been shipped to me either on time or earlier. So, thanks Amazon.
