I just ordered IO and IH and I am very excited as a first time user. What should i test ot first? Targetting a certain girl mainly…
Thanks 
From the sound of your post, id guess you dont really know this girl yet. Initially, IO’s more helpful because youre trying to increase the flow of conversation, which is most difficult right in the beginning. IO’s an icebreaker; Its perfect for this stage. Just IH solo in the beginning may may make her too comfortable which is not good because youd want to retain an element of sexual tension.
On the other hand, IO and IH were created to work together, so you could try them both at a ratio of 2-3 sprays of IO and 1 spray IH for the beginning.
Once she knows you a bit better, go heavier on the IH and lighter on the IO. 
I actually know her very well, and we actually bond quite well. We talk about deep topics and we both enjoy each others company, And we share some deep things, but she just seems too modest to be in a real relationship. I guess IO is the way to go. Oh I also got some IS as a gift
After trying each product by itself… Go with IS 2-4 sprays, IO 4 sprays, IH 2 sprays. Good combination. Pick up some Ammo next time to add to the mix. Good luck.
So two questions come to mind:
Is Instant Shine ONLY for self effects, and if so, does it effect someone already happy confident and in a good mood?
Secondly, once I apply IS or IO or IH, how long should I wait before re applying? Thanks.
