Hey Alex, Welcome my new Asian buddy 
I would prefer to give you recommendation of Ammo over TUTH, it is a subtle but effective pheromone, it signals out that you are cool sexy guy to people within your pheromone cloud, making people feel more attracted to you.
If you could add some social pheromones to your collection for helping you in social setting, get the communication start and flow smoothly, grab a bottle of IO, it help you to break the ice, making people comfort and want to talk to you.
Ammo is great standalone products for noobs and oldies here. If the budget does matter, go with the to-go size first. You came up posting here, you might know that you can get the $25 GC towards your purchase, plus don’t forget that you can also get also $5 from registration in the store as a reward points. So totally you can get 30 bucks for nothing, which could help you with the purchase of about 3 togo bottles.
Pheromones could affect a person person within range immediately, but the longer they are exposed to your pheros, the better the effect. Though please do not rely completely on the pheros to help you making the girls to jump on you or chase you like a dog see piece of meat in your hand. They are just help you a part, it just give out signal, and the rest is depend on the gals to judge on those sent signal. Read out here for more about What pheromones can do and what they cant
Tell me if your are unsure about anything.
Have fun.
