for me, it is a craze because the food is not tested enough for its marketed effects.
sure, many other people also claim to feel its benefits but the numbers just ain’t enough, for me at least.
then again, not all people are the same. you can give it a shot for science. nothing wrong with trying.
i tend to use the pain scale to give me a hint on decisions like this. so i guess the first question to ask before the pain scale is “am i in a state of shock?”
note: i am not in any medical field nor had intensive training.
