You got a pretty darn good set already
I would also recommend that you follow this
How to find your sweet spot… - PheroTalk Pheromone Research Forum
And find what works and at what dosages.
Also be very very careful with Androstenone products like TUTH because it’s very easy to OD on an athletic early 20’s male. You should produce enough naturally so you won’t need to worry about it.
Take a look at CTTM, its in the women’s section but it can be used by both genders. It’s a balance of IH and IO, and does work very well.
Welcome to the forum and good luck!
