I cannot say as I buy a kilo a month, by then the batches may have changed etc, as said all those vendors have had the best Kratom at some point. I usually email the owner and ask their favourite, read comments, reviews etc. A year ago I could have said but the last 10 months have been difficult with vendors running out of stocks etc. Out of those I listed I would just pick the best price and location for yourself. Sorry I cannot help more but I would be guessing. Best wishes.xxx
