Is this your first time mixing?
I’m going to tell you what everyone else will, and say that doing that in the bottle, before knowing how well it affects you, is a bad idea. If the effects aren’t well established for your body chem, you just wasted product.
What I would do is:
Use it to dose your product, and find a sweet spot for that, and I’m guessing only cause you’re new, that you haven’t established your P83 sweet spot/tested extensively yet.
When you mix in the bottle, most members composite for weeks, and from what I’ve read garners better results.
Now the reason these things are already made and set up is because there is a good reason there is a specific percentage of PA/Mones/Carrier scent that help fix the mones to your skin, and diffuse it at the same time. You mess with the ratios and don’t know what you’re doing, then you might not be able to replicate your results everytime.
Members here have used the product within itself to use the PA and scent already in a product to facilitate diffusion, however, remember that when AD makes a product, mones are in their crystal form, not liquid, and that adding anything else would skew those said ratios. The closest you can get IMO would be buy PA, with carrier scent, (I like Neroli) and then dillute your LS A1 there and layer it along with P83. Mixing in the bottle isn’t really recommended because of above reasons. This is really why even at this stage, I’ve rarely composited in the bottle, and only when I knew the exact results that I’ve been getting after layering my combos on my skin.
