I just started using it a couple of weeks ago. I usually mix it with my calcium and vitamins. Maybe I should full on dust with it once a week. I use it with everybody, whether they have yellows or oranges or not. I figure, what the heck, its another supplement. I'm sure it will enhance the old line UE vents from Josh's, as well as the variabilis and the auratus as well. I figure it has a relatively short shelf life like the calcium and vits, so I may as well use it before I lose it.
