You could try caffeine with L-Theanine supplements. Though I guess those could have lead too. The site I get mine from (bulk supplements) does have a lead warning when you buy, but as I understand it, they do that because lead testing is so expensive its easier to just put up the warning (which they need to be able to sell in California). Of course it could also be laden with lead for all I know. You can get L-Theanine from lots of places though and its most true teas (black, green, white, matcha, etc).
