What is a COA and how do you read it?
What does "mitragynin 1,42 %" mean?
Mitragynin is the main alkaloid in kratom. 1,42 % means that 1 gram of powder contains 14,2 mg of mitragynin. This value is declared for every batch.
What is 7-hydroxymitragynin?
A secondary alkaloid in kratom. In a natural batch, the value should be very low (up to 0,02 %). Higher values may indicate oxidation or an inauthentic product.
What does PASS / FAIL status mean?
PASS means the parameter meets specification. If it were FAIL, we would not release the batch for sale.
Can I download the COA?
Yes. A full PDF COA stamped by VŠCHT is available for every product under the "Lab test" tab.
