Last order from them was 2021. I bought 1 kg red borneo, but I told them I had virtually no effets (usually I had some "relax" effects) and so they send me another free 500 g saying it's a "next stronger batch", admitting that the 1st batch was a bit weaker. Then, I had long periods whit no kratom use at all, and now I admit that this 1st batch/1 kilo has some effects anyway . But indeed, I think that their batches in 2019 were stronger. since when do you think quality went down ?
