Hey Gurkan, I really like where you're heads at this seems like a perfect compliment. The two major missteps I notice in your understanding is that 501 isn't just 500 with silica added it is pure silica in a cow horn instead of manure and it is aged over a different period of the year. Also 502 is aged in a stag (male deer [some say a goat, or antelope, or ibex, etc will work]) bladder, not the stomach. Beyond that I like where your heads at. Have you experimented with this at all?
