Wow, I have been trying this Dr Amend’s Pheromone Advantage for about a month. Nothing. I really liked the idea of no scent too. 
I have been using it for 2 weeks now and it is working, but not strong enough. I ve notice me and my wife get really chatty, but sexually i dont know yet but i do see my wife touching her hair a llittle more often i dont know…but it is definitely working for me. i m 32 years old and i m using 1 dose. i ve tried 2 dose and no response at all so for me 1 dose is good.
i ve tried tuth, ammo,io and ih but no effects yet. still figuring out the right dose and the sweet spot. i m noticing the right amount and sweet spot is very important for the pheros to really work.
