15x kratom extract is the most popular kratom extract out there. It is the standard by which all other kratom extracts are judged. It is priced very economically. Keep in mind that we call it 15x kratom because this is the standardized product stocked by other vendors and 15x extract is the official name. This is the exact 15x kratom that other vendors sell. The alkaloid content is standardized to 15x, however we estimate the actual aroma to be closer to 5x, compared to non-extracts.
