What do you suggest if i'm thinking of trying ephedrine (ephedrine sulfate) to lose weight?

I would discourage: You from using this chemical. Take the healthy route. To lose weight insure that calories burned > calories consumed. Drink at least 8 - 8 oz glasses of water per day. Aim for at least 5 servings of vegetables ; 4 servings of fruit per day. Use whole grain when possible. Avoid sodas, alcohol ; junk carbohydrates. Get in a good mix of aerobic ; weight lifting exercises.
