Hi NSS, welcome to pherotalk!
What are you looking for out of pheros? I get that you are into the science of attraction, and that you want red heads, here’s something you should check out.
What are your goals for pheromones? Since you mention you are shy, IO is a great pheromone to make you and others around you chatty. I would definitely stick with ammo and IS as well. I’m unsure of why you want a314 atm, I’d go for it’s lighter counterpart IG for a person your age.
