I have tried different strains of kratom extracts and the new guinea 20x is awesome. I used to pop a lot painkillers, mostly
hydrocodone, which only lasts about 4 hours or so. Kratom 20x, feels like being on about 4 of them, plus putting you in an absolutely fantastic mood that litterally lasts all day long. It is rather expensive, about $80 for 24g, but a half a teaspoon is all you need. Taking larger doses very similar to heroin. Best relatively unknown drug out there, in my opinion.
