Hi ngage and welcome.
I am not aware of pheromone studies specific to ADHD children. In my opinion, I do not believe pheromones will have a dramatic and noticeable effect on children with serious issues such as this.
A314 may have a mildly noticeable effect, but works better on adults from what I understand. It helps give you an alpha aura, and assists people to trust and respect you. Communication products like Instant Openness and Instant Honesty may also help.
If you have not already, have a good read of The Mens Guideand let us know if you have any other questions.
So we can make more targeted suggestions, and so you can qualify for the gift certificate - can you let us know more about you and your personality. Are there any other things you are targeting through the use of pheromones?
