Hi Julie Anne, welcome to Pherotalk 
I started as you did, in college curious about even the idea of pheromones. One of the things I wish I had done better was to get an idea of what I wanted to accomplish with pheromones. To help you, allow me to ask a few questions.
You said you’re interested in feeling more confident. May I ask in what way? What I mean is, there are pheromones for feeling sexy, and there are others for breaking the ice, and there are yet others that give off that air of sleek, put togetherness. There are still more that deepen conversations, and one particular favorite of mine (Instant Shine) that elevates mood almost like a drug.
It helps us (in giving recommendations) to know a little bit about your personality, and about your social habits before we go spouting off names of products. Also, sharing a little about yourself can earn you a gc which can help with a first purchase.
The best thing about Pherotalk is the huge volume of archived information at your fingertips. For instance, this thread. I encourage you to read a few threads in the women’s forum as well to get a feel for what can be done with pheromones. Feel free to ask any questions that you may have in this thread.
Congratulations on the start of your pheromone journey
