Just remember that this sub is full of shills and shit callers, dealers are active on here using multiple accounts, battling each other for sales. Bad kratom usually just means weaker, requiring a larger dose. Out of all the kratom I've bought I've yet to have been sold a completely inactive product, the worst I've had needed over twice as much as my usual dose, which caused stomach upset, but with a low enough tolerance it will still "work". I just bought Yellow Kasung from Kratom bird recently
