I don't really have a preference as long as I don't feel nauseous or experience any sides from it or especially the AAS that I'm using it for then I'm happy.
I believe many prefer Caber overall but I haven't noticed anything yet personally that would cause me to prefer one over the other.
I've also used that B6 (P5P / Pyridoxal 5 Phosphate) before and found it helped at least on moderate doses.
