Bests & Worsts Reviews from Amazon

First, a rebuttal of criticisms. The top does not have a seal to break to open, because the entire bottle is wrapped and sealed. If your bottle never had a heavy plastic wrapping, then it was opened. Secondly, after opening it is refrigerated because it has no preservatives (if you took organic chemistry, you avoid very deadly poisons) nor alcohol (my antibiotic treatment requires abstaining from any amount of alcohol). So I will either carry the bottle with me and keep it away from heat, or carry the bottle with a small ice cube in a tiny baggie or a cold cup. (If you can tolerate a little alcohol, you would probably prefer one of those products). I have used some of this for more than 30 days--if you are careful opening it each time not to introduce contaminants, it will last longer. But this is so good that generally it doesn't last that long. I have an "evil brew" of liposomic supplements I take that is unbelievably bad tasting. In the past, I have used to droppersful of stevia plus some Monk fruit so I can get it down. After I switched to this Monk extract (plus the stevia), the drink actually started to taste somewhat good! Considering the high concentration (relative to other Monk liquids), the relatively good sized bottle, and its taste, I don't really care too much about the cost--alternatives are either bad for you, bad tasting, or even more expensive to use. I don't use the granulated Monk products, because for me they don't sweeten anything AT ALL, even the highly rated Lakanto (which makes a great chocolate product). Monk powder is the most powerful of all, but it is extremely expensive to buy a jar, and it doesn't mix well.
