supposed to mean 2g of 50x leaf extract, meaning 100g of plain-leaf Kratom were used to make those 2g's of kratom extract. This is obviously an exaggeration, but unscrupulous vendors will do what they can to sell you extracts even if they have to lie. This is why I recommend everyone curious to try Kratom to stay on plain leaf only and not use any extracts, ever.
I would recommend starting out (and sticking with) plain leaf Kratom, and I've found
this Kratom dosage chart very accurate. Most "good Kratom" people talk about on forums is the "super grade" kratom listed on that page. I would recommend starting out with 3-5g of super grade kratom, or 8-10g if you have an opiate tolerance. I would recommend dosing no higher than 10-12g in one dose, as that is when the unique "Kratom nausea" and eye wobbles kick in, and no more than 1-2 doses a day, because that is when serious phyiscal dependence sets in.
My best recommendation: if you can stick to under 4-5g of "good" Kratom dosed
only once a day, you can use it for pain, anxiety, or depression and feel extremely minimal side effects and almost no physical dependence. Plain leaf Kratom is delightfully weak, and helps pain patients and ex-opiate addicts live their lives free of crime and full of productivity if they so choose to, and helps them maintain their "sobriety" in a manner similar to a very weak suboxone (socially, not pharmacologically). Illegalize plain leaf Kratom, and you will have thousands of ex-opiate addicts and current pain patients resort to crime or illegally obtained Rx/street opiates; it really
is a miracle plant, so let's be responsible and not abuse this wonderfully weak plant.
