HI Hidaya, Welcome to the forum 
I am assuming you already ordered it. Did you get the to-go or the full bottle ? Its a really good product and one of the forum favorites. If it were me I would have started you on the regular consumer products instead of the advanced but its ok if you ordered it we will help you with it. If you havnt ordered yet I would suggest Instant sexiness, Instant Shine or Instant Openness to start with. These are some of the consumer products. Advanced products like the Test mixes and putatives are for experienced pheromone users to try and report back to Androtics on. They are not ready to go to the consumer stage just yet but alot of the mixes are good.
Mx135 is a fun party like mix with a touch of sex appeal. It attracts attention of a light fun nature, smells like chocolitini, and yes it works. You will find some posts in the ladies section on Mx135.
Its true that pheromones work different on each person depending on their own natural pheromone signatures and how well they learn to use the product but the differences are subtle. You also need to find the correct dosage for you. Your friend may need 3 sprays to see reactions and you may just need 2. Sometimes you will run across a certain pheromone that just dosnt do it for you but I wouldnt worry about it. while it happens most people do see some sort of results once they figure out the correct dosage for themselves.
Also get your mones in the to-go bottle at first so you can see how the product works for you and if you like it before you order the big one.
Here is a link that will help you a little.
Steveo will be around soon to tell you when to expect your GC. If you have any questions or just want to chat come on down to the ladies section.
