I do a modified RSO. I don't put in the double boiler, instead I add it to 2 gallons of OJ. (using one ounce of good bud) I get 100-150 doses per ounce depending on if used for buzz or medication.
Interested in adding the letithin (sp) since the citric acid in OJ probably limits how long it lasts. Interested in ideas for adding it to something else. Considering capsules.
