Pretty sure CDN is your go to guy on here.
Buy M. speciosa - EntheoFarm
is your place to go. They have really cheap 10g samples you can try and fast shipping. All is high quality. 5g of one of their farmers blend was too much for me. 3-5g is usually a good dosd, though I've done 10g all at once too.
Truth be told, I don't care for Kratom. Just smelling it gives my body the shivers. Really hard for me to get down, so I don't really fuck with it any more. High isn't that great either, IMO. I'd probably like it if I could get it capped.
I'm really starting to like Kava Kava.
