I believe any of the top bee suppliers will send it to you. Theres also ApiLife Var.Amazon can't ship it to our address. Probably WA State law. This state is getting dumber every day.
I'll have to see if I can get it elsewhere. If not, we'll just have to make it.
Very easy. You can get thymol crystals from Ebay or Lebermuth.If you do, please document how it's done.
