Hey, and welcome to the forum.
An IOI is a term coined by pick up artists, I believe. take a look at this link How to Tell a Woman is Interested In You -- The Master "Indicators of Interest List"
You should not expect girls to flirt with you. What you should expect is that pheromones will make things easier for you. It is 90% you, and 10% pheromones. Without action, nothing will happen.
Something that I’m not very good at but I know should be the case when it comes to attracting women is that you should never expect an outcome when talking with a women. When you become outcome dependent, women can sense that there’s some hidden agenda which is not attractive to them.
I’m not sure about any of the pheromones you have listed, but I am sure about the pheromones that this company has to offer. There’s a link here:

Which will explain how you can qualify for a gift card. With the 25 dollars, you can buy two small togo containers of pheromones and you can test them out yourself. I recommend ammo for attraction. Instant shine will be a vibrate and young charasmatic type pheromone. There are self effects for some people, and you may find yourself smiling when you apply some of these pheromones. I know I can’t help myself sometimes. This company also has a ridiculously good return policy so you really aren’t losing much from trying their pheromones.
Just from your post, you seem very high strung on having these things work. My suggestion is that you relax and remind yourself to have fun. Nothing is more attractive to a girl IMO than a man who knows how to relax and have fun.
