Good first reports! Keep them coming!
It could have been the Instant Shine your friend was smelling. To me, sometimes it has an “off” smell, but not bad, not overpowering. Or the place could have really just smelled like sweat. 
I think you should stick to one product right now, to be honest. If you start mixing too many combos, once you start noticing your hits, you may have a tough time isolating which mix is working for you at what dosage, and you will have to go back to the beginning. On your blind dates, I would use either Instant Sexiness, Instant Shine, or MX135, but not all three. To be honest, I would use MX135, simply because I think that is the show stopper. It sounds like you may not be certain what is a hit and what isn’t, however (the boy in the bar was definitely a hit, your bosses singing your praises was a hit) so you could be overlooking the effects the pheros are having on others. You should read this thread of Tisha’s if you have not already. It could help you out a lot in this area!
Which Instant Sexiness are you using? A or B?
