what age for stronger doses?

Hi all,

I just recieved my pheromones today and am testing each one out individually to gauge the effects. I have seen some people write about the higher strength products and it makes me wonder. At what age do you want to get a stronger version of ammo?

I am 38 years old. Is the regular strength version not going to be strong enough for any results? I dont want to use too much as I dont like overuse of fragrances no matter what type they are. Should I have ordered a stronger version?

Thanks.

They do recommend the 2x version for men over 30.
