Hey im 19 male from NJ and i saw a post about this stuff in a cologne thread, they said no matter how good your cologne works for picking up girls, this will be better. i figured i might as well try it and im going to buy TOTH first. i dont really understand how to use it , but i plan on reading up and figuring it out. i dont understand why do you have to mix so many different ones to work effectively? 
Welcome.
Read https://pheromonetalk.com/t/how-do-i-qualify-for-a-25-gift-certificate/19934 to find out exactly what you should tell us that will help you best. Like your personality, the personality of the girls you want to attract, as well as the environment (schools, work, clubs, etc.).
Hi Ayanega - Welcome to Pherotalk.
The answer to your question about mixing the pheros is that you don’t have to mix them - Each phero is a standalone mix that can be uset singly or together as the situation requires. Or that they can be used to steer or moderate the effects of another phero in a different way.
I would suggest you hold-off TUTH for the moment, unless you are already in an active sexual relationship with someone as it is not really a social phero and at your age, it could easily backfire on you because you are liable to be producing a good amount of Androstenone yourself and girls around your age tend to be repelled by too much of it, you can end-up being seen as overly horny/agressive or creepy!
The social pheros like Instant Shine, IO, IG and IG are often far better for attracting younger women (teens-mid 20s) or the more balanced sexual/attractant pheros like Ammo (in small doses) would be a far wiser choice. Have a read on them.
Have a read of the start of this thread and follow the links for all the info you need to get started using and choosing pheros effectively:
I would say you could go with
2 Sprays Ammo for general sexiness
1 Spray IG for a little maturity and status and to help buffer the None
1 Spray each of IO and Shine for a charismatic, fun likable vibe and to further buffer the none.
Don’t worry about overbuffering. The none is there and it has the attraction upping effect. But with the buffering effect from the other products it will be more acceptable for younger girls that might otherwise be uncomfortable around a high None signature.
Welcome to pherotalk Ayanega!
So that we can assist you even further and to issue your $25 gc you will need to give me more information.
I would like to know :
What your personality is like
How did you get to know about this site
Thank you so much, everyone’s information was very helpful but yours the most. I decided against TOTH and I am reading the posts you told me about. Thanks again.
What is your personality like: i extremely outgoing, i work as a waiter and people always compliment me on being so open and funny, and being able to leave a good impression very fast. I also am a Caucasian living in a town that is 89% Hispanic, which defines my personality a lot. I am obviously single, and i spend most of my time at work, or in school.
How did you get to know about this site: I was in a conversation about colognes, and someone mentioned this site. I didn’t believe it at first, but theyw ere very convincing and eventually I thought it was worth some reseacrch
Hi AYanega, welcome to the forum!
The others have made some great suggestions - for your personality and needs, I would recommend Ammo, which will enhance your confidence and sex appeal nicely, and Instant Honesty, which will cause others to feel as though they trust you more and is also great for creating and strengthening emotional bonds (which is important for women to feel in order to get past the “friend” stage).
If I may, your personality is shouting IG at me - Maybe try a little at work and see how your customers respond and if your tips are affected? 
OK, after what I said about TUTH, I’ll now revise things slightly and say there is a well known affinity between Hispanic women and none! :o They tend to respond better to higher none levels right across the age range. Have a search here and you will turn up a good number of threads discussing this.
However, that does not change my advice about Ammo. You will still be far better testing and getting used to using and recognising/evaluating your hits with Ammo first.
Thank you for the additional information. I think I am a scatter brain. I managed to look over your thread to ensure you replied and gave more information , issued your gc and somehow did not reply to the post.
Either way I see you wasted no time in placing your order.
Your gc was issued!
