Just fill me in a bit, I'm not sure I'm interested in buying just now, but I'd like to have the name of a good source in safe keeping for a rainy day or something. And any other info would be appreciated, about where to learn more about the positive and negative effects of available chemicals, doses; or at least a list of chems worth looking for so I don't have to sort through an entire inventory trying to figure out what things are.

Thanks in advance.
