Welcome to the forum! We always suggest you try each one by itself a few times so you can see what it does. This way, you can develop your own strategy for combining the products in a way to get your desired results.
I’d also recommend reading and absorbing the information in this thread:
As for the products you’ve ordered, TUTH is the sexual product, and at your age, you’ll be fine wearing a couple of sprays. The older we get, the less androstenone (primary component in TUTH) we produce, so there’s less danger of overdosing on it. We’ll usually tell late teens and early 20somethings to go easy on it, but you’ll be okay. IShine is a very good mood brightener (hence the name) that can get everyone around you cheerful, including yourself. I usually give myself 4 to 5 sprays of it for work, so it’s a good safe pheromone to wear in a variety of situations. IFM is a pheromone for fostering comfort and trust in women, but it has been known to produce mood lowering effects in men, including the wearer. If you notice you seem a bit down or maudlin after wearing it, try spraying to the back of your neck. IO is a pheromone to get people to be more open to conversation. It’s been referred to as Instant chattiness.
Just remember that pheromones are like gas in the tank. Without a spark to ignite it and drive the pistons, it’s not going to do anything. You provide that spark. Make sure to present an image congruent with the pheromones you wear. Be the conversation starter, and make sure you carefully observe how things are going.
Hope this helps!
