Question: if mitragynine and 7-hydroxymitragynine are the two active alkaloids in Kratom, what do the different strains have to do with the effects you get from Kratom? It seems to me that the only thing that matters is the percentage of these 2 alkaloids in any one strain. Personally, I’ve tried pretty much all of them, but green anything works the best. I like the euphoria I get from the green. Red strains are supposed to be more euphoric. Not the case for more. I actually felt less (much less) of an effect from the red(s). I’ve also found that the more bitter it is, the better. I really think that all these different stain names are just a way to market/sale Kratom. I’ve had people swear by one certain strain over another. I think a lot of the reason they do is psychosomatic.
