About a year and a half ago I purchased 100 grams of Ma Huang (Ephedra Sinica) 5:1 concentrated powder and I never used because I am not sure how to figure out proper dosing as the old ripped fuel, stackers, etc which I believe was 20% per serving.. The ephedrine content is approximately 10%, but total alkaloid content is not provided with the data. Does anyone have any Idea how to dose this?
