Hello Jon & nice to have you as a member of Pherotalk 
Well for me i have heard of Realm but never use it so i can’t give any comments to it. Glad you found this forum, you will learned a lot of phero info here or what the pheros here do. Well you can decide to try out the pheros here if you want after reading what they can do.
Anyway, you need to tell us a bit more of yourself, what you hope to achieve by using pheros & what kind of effects you hope for as this will help us in helping you out. Here is a link to more info about the pheros here> Mens Pheromone Guide revised 6/15
I will be back to check this intro. See ya
