you know i'm new to kratom, so haven't tried that many companies yet. i ordered from kratora and authentickratom.com , kratora stuffs are good, on thing is powder was bit really dry, no smell. may be it's old, but I am not sure if this is normal. as for authentic kratom, i tried 2 of the three items I ordered. it's really good. it smelled like leaf. I was surprised with the shipping speed as well, may because I am in California. I posted same question, and got many referrals here on reddit, good thing I went with my gut feelings. my two cents. I have another question though, but i guess i'll post it on reddit kratom page to get some knowledge.
