Obviously we've discussed the different effects from various kratom products so you should have an idea of where to start. If your still unsure where to start, you should try a few kratom samples in small amounts until you find what your looking for. In our Buy kratom section, we link to a few vendors and you could try emailing them to ask if they can put you together a kratom samples pack. I'm sure they will consider this if you ask nicely. If your looking for Free kratom samples, I would place an order and ask for a sample of one of the other strains.
If I wanted to put together some kratom samples, it would be Thai Kratom, Indo Kratom and Kratom 15x extract. Of these three kratom samples you should find what you are looking for.
