many sources in china. all buy from same producer. it comes down to lowest price trader. 40 usd/gram if u cut middleman. i spoke to many sources last week
seti takes its time to work. if you ask me 5% seti equal in strength compared with 0.5% OC. its weak as s hit with stopping itch i will try 10% next week in K&B solution with ru.
$40 a gram doesn't sound cheap for Seti
