Hi Chris - Welcome to Pherotalk! 
Yes, there are a good number of pheros that could help you here. Can you give us a little more info about the girl you are interested in - Particularly her age?
Until you tell us otherwise, I’m going to assume she is of a similar age to you and for that, I would suggest you look at the products, Ammo, Instant Honesty and Instant Shine. IO could also be useful but you seem to suggest you are already well-into talking/flirting with each other ao you may need to deepen your connection rather than open-up conversation - This is one of the things IH is great for.
Ammo - Is probably the most suitable product for a guy of your age, it is an all-round sexy/social/masculine attractant that carries a good healthy impression to people around you and can give a bit of a useful confidence boost to yourself. As Ammo contains androstenone, you will need to do a bit of work to find the dose that works best with your own body chemistry/personality. See the Sweet Spot Guide that I am going to link and don’t go spraying-on too much at once.
Instant Shine is a happy, confident, feelgood/good to be around mix that helps people relax and loosen-up in your presence. Its a good way to get attention focused on you.
Instant Honesty - Well, as I said above, this promotes close and bonding conversation and when steered by the happy/feelgood nature of IS, it makes a mix that gets straight to the heart of things with people.
Now you ask about TUTH. Well, it is a very overtly sexual androstenone product that is really designed to enhance sex between people who are already in an established sexual relationship. Its not so good for breaking the ice with someone as it is the chemical equivalent of taking tour cock out and saying - “lets fuck NOW!” Which although you are flirting, may not be be exactly where this girl wants to be just yet? However, TUTH can be useful in very sexually charged situations like clubs/parties etc, where inhibitions are lowered and you can be much more sexually overt with each other - Especially when moderated by the likes of Instant Shine to keep the atmosphere fun and happy or A314 to enhance your status and sexuality, however A314/TUTH mixes can go down better with women from their mid 20s and upward as younger women tend to respond better to socials and smaller amounts of none whilst older tend to go for the more overt/status signatures. Its up to you to evaluate this girl’s potential response. Any idea of past BFs or crushes may help but don’t get too obvious as nothing kills attraction like talking about ex’s. 
All-in, I’d suggest you stick to the likes of Ammo, IS and IH to start with, as the socials help promote all the other feelings that conspire to full-on attraction and save the TUTH either for the bedroom, or when you are very close to it.
All the basic info on choosing and using pheros effectively is on this thread:
Learn it well and pay particular attention to the sweet spot guide for using none products. Socials are a good bit easier to start off with but try to keep them in proportion to your none products as you don’t want them to soften the effect too much.
This thread on application points is also very useful:
And finally, maybe cut-down on the text flirting and increase the amount you do in person - Again, it works far better!
