I’m kind of confused by the marketing material they use. They’re selling this Attract Mate Pheromone Concentrate, but the survey based study they draw reference to has men testing Androstenone Pheromone Concentrate (APC). APC has a very minute pheromone content. In fact it was used in older mixes for the added fragrance, NOT the pheromone content. Given the inconsistency with androstenone already, with such a low phero content in APC, I highly doubt the credibility of that little study.
Unless it comes from a reputable store, I wouldn’t trust a product that doesn’t give a clear indication of what the pheromone content in the product is.
