Kratom.eu Their bigtrea 1.5% is just amazing... Green Borneo is even better. When i try Green Borneo from kratom birds and green borneo from kratom.eu which is their bestseller I can see how much difference is. It is probably the most expensive from EU kratoms, but it is real kratom that 5 grams works like a charm. Premium Cammeo from Kratomdudes also works great
