correct, at that price it can't be endotoxin free. they're talking about 120 bucks a kilo. endotoxin controled starts at 850 bucks a kilo in mass bulk. a kilo is around 1100 to 1200 bucks. Thats why I never made that kit I was working on. and you really don't want to inject the stuff sub anyways as the injection volume is way too much, the best I got in terms of mg/ml was 80mg/ml. remember that it takes at a min 7.5gram of the cyclo for 1 gram of base and that is hard to do
