Alter ego has been reported to be a little overpowering. People do use it with success. Turn up the heat seems to be more refined and at times easier to use while still maintaining a reliable success rate.
Honestly the only non androtics product that I will consider purchasing is scent of eros. When I buy something from androtics I know it’s going to give the desired effects. That’s why i’m here. Love scent never presented its self to be as formal of a company as I desire. I am partial to androtics so you may want to get some other opinions. Do some searching in this forum about love scent, NPA, Alter Ego, and if you still need some clarification as to the difference in effectiveness between the two companies start a thread about it. Love scent vs adrotics. Couldn’t hurt 
This is a thread in the lounge I think you should check out.
