Welcome from a fellow Texan…thanks for sharing. Let me first stat off by giving you a couple of links you should definitely look into.
Those two threads above will get you started in learning about the products and what to expect.
Now onto some suggestions:
For confidence and respect that you’re wanting: A314 this I now refer to as the life changer. You will be putting off that alpha male vibe and the self effects will help you become congruent with that vibe. When I apply my drops, I smear a bit under my nose so the self effects hit me that much quicker.
You will see people post that it makes them walk taller, talk deeper, become less reactive (this is the best part for me). Not only will your co-workers, bosses and clients notice, but ladies will too.
This is one of those products that you just can’t leave home without. It’s the American Express mone from AD.
IG another alpha vibe inducing product, but is less intimdating for some. However you being 37 you can pull off the A314, whereas IG good for all ages, would give a younger guy respect without it having older alphas and alpha women questioning if this guy is full of crap or not.
IS get it for the self effects as well as the effects on others. This is the happy social product. If you want to see if mones work, spray this on yourself, inhale and then try to wipe that grin off your face, I dare you. 
IO will help lube up the convos, get people talking to you and you talking to them. Its a bit more subtle from my limited experience vs CTTM2 which is the one I swear by. The name Come Talk To Me for the product lives up to the hype.
IH will help open people but makes for a deeper connection, people will reveal stuff to you. Just be careful, you will reveal stuff to them. God forbit you killed a homeless man just to feel alive, because you just might let that slip out. LOL
Ammo is a good all around standalone product but mixed with others is amazing. It does have a sexual attraction vibe to it, but is buffered with social mones to make it safe for use anywhere…vs tuth wich is purely sexual aggression.
My favorite mix right now is A314, ammo and CTTM2. I wear this at work and play. The mi makes me an attractive, high status male who is approachable.
I make this suggestion to anyone and everyone. Have fun…
Now once you get your mones follow this thread
How to find your sweet spot… - PheroTalk Pheromone Research Forum
Finding your sweet spot through testing gives you an idea on what wors best with your body chemistry, and allows you to see what kind of results you can achieve from each mone.
That way when you become proficient enough to mix a few together, you will know what exactly is doing what.
Once again have fun with this, and everything else in life.
Reframe those presentations into a challenge. A challege to prove first to yourself that you can do it.
I used to have a fear of public speaking, even though I did stand up comedy for 2 years, it was why I quit eventually. But since then, I have become fond of getting up and speaking. Quite honestly I enjoy the attention.
I look forward to seeing what you choose, and how it works for you.
