Blessed be eBay, purveyors of fine poisons that they aren't equipped to regulate efficiently.
Recently the floodgates have opened on As, too. GalliumSource sells it by the ounce. Thallium, too. A few years ago, this wasn't the case (so much).
Uranium, iodine, red, white & black phosphorus, bromine are on eBay very frequently. Another guy sells Na, K, & Cs.
A huge chunk of uranium 238 was just offered there. Technetium salts, too. |
