Review (5/5): as good as any androstenone product
I've purchased one bottle a couple of years ago and still have some left. It has only androstenone in it which is the alpha male dominant pheromone. It definately works, so use discretion when wearing it. I would suggest that you not use it in a professional environment where any kind of sexual tension would not be appropiate. I would also not suggest men use this pheromone if they already give off a tough guy image. I think it works best for men who give off the nice guy image. Also, be aware that this can cause aggression/aggressive behavior in men. Use too much and you will repel women, so experiment with the doses.
When using any kind of androstenone pheromone product, be aware that you are more likely to get into fights/arguments with other men when wearing it. It's good to be aware of what kinds of atmosphere it can and will foster so you can be one step ahead and avoid conflict.
