Just noticed that product page for "The Edge" at love-scent now lists the ingredients as Androstenone, Androstenol, and Androstadienone. Bruce had earlier mentioned that The Edge is nothing but diluted NPA, so does that mean that these are the constituents of NPA as well? For years people have wondered what's in NPA that makes it so sexual and have chalked it up to the "secret ingredient". Now this new revelation makes me wonder if the secret ingredient is nothing but a mix of other pheromones (like Androstenol and Androstadienone and maybe others at even lower concentration) and the reason for not mentioning them was to simply preserve a proprietary formula and maintain an intrigue about the product. Many people who can smell Androstadienone, have for years maintained that they can smell it in NPA which now makes a lot of sense too. I think the reason NPA is so sexual, and for a lot of people seems to do something that can't be replicated by any othe...
