We do not recommend taking only Stem and Vein products because they contain lower concentrations of kratom's alkaloids. This may result in a squandered dose. Furthermore, we believe that more research into Stem and Vein is required before a firm decision on its application can be made. Here are a few examples of what scientists are still trying to figure out about stem and vein kratom: • What exactly is the alkaloid content? • What effects does it have on other kratom alkaloid-containing products? • Is it compatible with any medications or supplements? • Is it a genuine kratom potentiator or a sham? • Is it different from other kratom products in terms of effects? • Could it be used to target different areas of treatment (ailments, for example)? As of the time of writing, kratom science had not yet investigated Stem and Vein as a distinct kratom preparation with potentially varying effects. Instead, modern scientific research correctly focuses on alkaloids derived from kratom leaves.
