Finally!!!! ...the cutting "Edge" in pheromone technology The Edge pheromone spray After two years testing/development and two months of negotiating and hardest of all, just waiting for the darned first shipment to get here, I am proud (and greatly relieved) to finally announce the release of the mighty Edge from LaCroy Chemical. While the exact formula is not yet released by the manufacturer, there is a guaranteed total pheromone content by weight of 2.4 mg per bottle, making it a good value bang per buck next to the big boys. "Try it, they'll like it." Men's UNSCENTED version Contents: 24 ml Guaranteed 2.4 mg pheromone content per bottle.
