Difference in Kratom types?

I was wondering what the difference is with Kratom between strains. Also, I'm planning on getting an oz of powder. Which is the best strain for someone new to Kratom (I dont neccesarily mean weaker ). I'm looking for something more euphoric and maybe relaxing. These are the ones I'm looking at:

Green Riau Kratom Powder
Red Vein Borneo Kratom Powder
White Vein Sumatra Kratom Powder
Red Vein Sumatra Kratom Powder

 

Kratom 15x is one of the strongest forms of Kratom and is active at about half a gram dosage.

 

Idk man all i know is its a leaf, good to see you still around here superphysch, Get ahold of me i might make a new account i cant get on chatroom anymore for some reason.

 

There are several different types of kratom on the market: leaves, powder and extract. Dried leaves are the most common form of kratom.

 

Yes, I agree with you Aalina, there are several varieties of kratom is available. Mostly the kratom is come in many forms but extract and powder form of kratom is best. Kratom is more effective medical herb that is mostly used as a medicine for many type of physical problems.
