you buy the pellets from a vet supply. Well, you buy the cattle injections which contain pellets, remove them, and then convert. The conversion is done by getting an aromatherapy kit from
www.finafarm.com and converting the pellets into inyectable gear. There are other aromatherapy companies, but that is the one that supports EF! I don't have the balls to use fina or personally make a substance i intend to injest with a needle!
