has anyone tried the purity test by MMC international? my concern is that it will not work for tar if it works at all. Anyone tried it? 10 tests are 50 bucks on amazon. I would like to test some, any suggestions on other ways to easily/safely test?
bump.... really? noone tried it? Id love a way to test purity. This would help the using population in general. much less OD if u know what your dose is at a certain purity
