I heat VG to make VG less dense and thick, and facilitates mixing of all ingredients.
I heat the VG, then put the aromas and Nicotine and shake for 30s\1m, then leave it alone for maturation.
I do not shake anymore, I did it in the past when I was shaking a little daily and did not have good results.
After all, why do it?
The initial mix is already made.
