Hello Sam!
Welcome to PheromoneTalk! 
Dropped your GC yesterday. Kindly check your inbox and spam folders to retrieve the code. It’s ready for use. 
Great advice/recommendations you’ve got, and the choice to start with UPIP is the best for a beginner like you. I suggest you search around for “sweetspot” testing in the forums and focus on getting your sweetspot per molecules first before embarking on combines molecule application. 
Regarding A314, there is no alternative. Well, from my view point at least. Others may claim that there is one, but eventually the choice of “alternatives” depends on their taste, on the hits they’re looking for, their financial capability, and of course, for some, on their vested interests. But coming from AD, A314 is A314, and we claim its consistency. And A314 is available. 
Re: other products mentioned here despite not being sold by AD, there are varying reasons for that. But as long as those, we’re mentioned as part of the discussion and not by directly nor indirectly selling or promoting it. AD does not host anyone who sells other products in PTalk forums. Everyone are encouraged to report every post they think as commercially spamming, simply spamming, annoying, out of order, not respectful with other members, and other reasons everyone might think worthy of reporting.
In your case, since she’s already a GF (meaning: you are beyond first base), I guess the best move is to make her feel as natural as she can while she’s with you. Since she’s already a GF, it’s given that any time of day, the two of you will get intimate. So I suggest to expose her first with IShine. It’s good to affect her strong personality around you.
Then introduce the IHonesty around her. If IHonesty made her talk, as in talk intimately with you, she’ll assume and believe that she’s doing it because you have something in you and she’ll like it. Don’t make the IHonesty an everyday molecules with her, it’s best to use it with her everytime you want to sit or snuggle and chat, it’ll keep her interest to see this “mystery” in you.
Now, regarding personality, I assume that you are not an alphaish male. And thus you will have difficulty on keeping up with the A314 vibe. In fact, some of the A314 complainants (not all, some) gets the A314 miss because their personality is the complete opposite of A314’s vibe. A number of users too has this misconception that by merely applying A314, their personality will change, and they only get frustrations everytime they fail to see the realization of that misconception.
I will suggest for you to try IG first. And when on a date, try IG + IHonesty combo, bring along the IShine in case there’s a need to lighten up the mood, and TUTH, in case you wanted to stealthily tease her.
You can use pheromones daily, although we strongly recommend that you choose a no-pheromone day per week.
