I have a female friend whose obsessing over using ephederine and caffeine. I have used it successfully in the past, but i dont want to give her wrong information. I want to make sure that its going to be effective and not harmful. What should the dosage be for women? When i take it its usaull 25 mg ephederin with 200 mg caffein two to three times a day. Im thinking 25 mg eph/ 200 mg caff twice a day? Or is this too much for a girl? what should the reccommended dosage be? Dont even know why she needs it. Shes 5'6 and not fat at all. Dont know her weight maybe like 110 maybe more not sure.
