Like I said before, the vast majority are Asian. My program has alot of japanese people in it, mostly asian born although I had some great hits from some american asians as well(a few from California, 1 from Boston,1 from london, and 3 from Italy.).
I guess this would be a good time for me to mention some things about myself. I’m a decent looking american guy(I’ve been told about an 8). But in my experience, that doesn’t matter a whole lot. I recently took a mystery method bootcamp course. While it is hard to run what the MM guys would refer to as “solid game” here due to the language barriers, what I have learned(and I think this is more important that most of the structural issues guys have) is to go out and have fun. That is the key. Have the highest energy fun time you can muster, and due to this you will have other people excited. You can then feed off of their excitement and keep the cycle going. When you do it you’ll know what I’m talking about.
Now, to get at the meat of your question.
No, this is my second trip to China. I spent 3 months here (pheromone free and ignorant) last fall. I understand that there is a certain amount of extra attention I get just for being white, and I know what it is to be here without the aid of pheromones. Boys, I want you to listen up and listen good.
The average guy is a 5 in a girls eyes before he opens his mouth. If he’s a model, he might be a 6 or maayyyyybe even a 6.5 if he’s really a pinnacle of human creation. Its what you do after that that really decides whether or not you are considered the high value guy that whatever girl you are around has been hoping to meet. So regardless of the fact that I’m american(especially in expat ridden shanghai), its much more important that I don’t let girls intimidate me, and that don’t try to come off as someone I’m not. I’m (becoming more and more) congruent with who I am, and I’ve really started to see it give me results.
I don’t wear pheromones during all parts of the day. Only parts where I know im going into situations where I intend to be social or in close quarters with people I’m interested in. There are other times when I’m out and about just doing daily things like going to the grocery store or eating dinner when i decide I want to be social with someone I see across the room. I use these interactions as a baseline.
Yes pheromones are definitely amplifying the reactions. There is no doubt in my mind. I see the DIHL’s and the way my teacher stares at me(Its bording on 100 times a day. Today actually turned into blatant open flirting to the point where the class was no longer focused on the Chinese lesson and simply focused on me and the teacher. To answer your next question, no this has never happened before nor have I ever believed this could happen to me. This doesn’t happen to me in my daily life no matter what country I’m in.

However, Always remember. All you will ever need to get women is what you are born with. The pheromones are just bonus points that make things more interesting, in some cases, MUCH more interesting.
