question(s) about the mixing supplies

Hey i have a question about the 30ml bottle with EO plant i was wondering how would u use this? i know a lot of u guy like mixing ur own thing
what i was interested was the

30mL oil AND natural plant musks (which have little odor of their own, but help to time release pheromones and increase the diffusion radius around you),

Dipropylene Glycol AND 1mL of Ylang-Ylang “First” Essential Oil from Madagascar (clean smelling)

30mL plain Propylene Glycol (Propylene, not Dipropylene)

30mL plain oil (called dipropylene glycol),

1-the first one if anyone used please tell me if it worth it and does it help you? to me it sound like it makes the phero last longer and increase it output. Does it work like this?
2- one I’m just a sucker for a clean smell. does ylang-ylang
effect the pheros?
3-what does propylene glycol do?
4-whats does dipropylene gycol do?
5- and how do they differ?

Yes I’m on the road for nooby to pro and i want to know as much as i can

1: I haven’t bought any but I was planning to at some point. What you can do with them is mix in some high-concentration (112 mcg/spray or something) experimone or something, say from a to-go bought specially for the purpose. 10 parts the oil/DPG stuff to 1 part the experimone will give you about 10 mcg per drop in an oil base (which would last longer but not have the “in-your-face” impact of a pure spray)… You have to shake the bottle before applying as oil and alcohol will separate if left undisturbed.
2: ylang ylang is a nice smell, it may help to diffuse the pheros too, it won’t effect them as such except it may help cover the scent and disperse them better
3: ? dunno actually
4: DPG is like a “pseudo-oil”
5: ? dunno
