Stem and Vein Query

Hi Joey, Thank you so much for all your advice. I was just wondering if I could just use the stem and vein Kratom instead of the ordinary Kratom? I'm a new starter so I haven't used anything yet but with all the good things I'm hearing about the stem and vein, couldn't that be used on it's own? Would the effect be as good or do you need to take the Kratom leaf with it? I thought this may be a good way to start without too much of the worry of building a tolerance to it. Thanks again and please keep the great work up. Mary.
