a purity grade is a purity grade. it must be that pure to get that grade or certification. there is no "human consumption" differentiation. they will all tell you its poison to escape any liability whatsoever. jcrows is an exception and he is taking a risk. i do not count on him being a steady source. i see it more like a gathering of names and a big red light when he reaches a certain level of product flow. you can bet someone is watching like a hawk.
a sole source is insane. we need to open this up and find the product we want at a resonable price and buy bulk. you know jcrow is with his quadruple digit markup.
