Hello Praetell!
Welcome to PheromoneTalk! 
MB works only for gay guys. And if you are trying to get the attention of straight males, I think the best result you’ll get is a friendly smile and friendly attention.
If you can be more clear too re: approaches, because by reading your message above, I am assuming that your approaches is actually an application.
If this is true, then I think there lies the problem too. Otherwise, please be so kind to answer these questions: How many sprays did you employ per outing? How often do you re-apply? What places do you go to when you are wearing MB? How do you approach your targets?
For the meantime, you should consider pairing it up with IS and/or IO, and the $25 Intro GC I dropped into your email earlier might help you in placing that second order.
Check out HankBuddy’s thread too for other initial ideas.
Happy pheroing!
