I agree, go on red is a beast. you can buy it off amazon or any other online retailer. Please be mindful of your health condition though, if you have a high blood pressure, or pre-existing condition, I do not recommend any additives at all, which are not approved by the FDA and without a prior consultation with your PCP as they are likely laced and may trigger something that you don't want to be triggered in a particular health condition. Always use common sense. Or else, better get on a diet and exercise.
