I have been making e juice for a while now, and i sell it. I have a couple good flavors that come in both 3mg and 6mg, the 6mg juice always taste a little bland compared to the 3mg. I use 100% Vg nicotine in some flavors and 50/50 Nicotine in others. my juices are usually 40/60 pg/vg. there is not more VG in the 6mg juice then the 3mg, so i don't understand whats happening. once i made a 12mg juice just to test it out and it was extremely bland!
