I have been purchasing product from Phytoextractum for several years. What first attracted me to this site was the analysis they posted of one of their Kratom products where they list the mg of mitragynine and the mcg 7-hydroxymitragynine in each capsule. Their product has been very consistent over the years. The 2 times I needed customer service I contacted them via e-mail and got a response same day with a resolution to my issue immediately.
