Sometimes, a pheromone product makes girls appear completely uninterested in me

(the invisible man effect).

When girls pay no attention to me or even

walk away from me, it can mean two things.
It could mean that I don't

appear masculine enough, i.e. women don't consider me a prospective mate. If that were the case, I would need to

try a more sexual-type pheromone.
On the other hand, it could mean that I

appear too masculine and threatening. If that were the case, I should use a more fiendly-type

pheromone.

How can I tell which way it is? What signs should I look out

for, in order to be able to tell whether a pheromone product makes me appear not masculine enough or too

masculine?
