I'm sorry, but I'm unable to find specific information about FVKD Seven Hydroxy 4CT Tablets. The product seems to be categorized under 7-Hydroxy, FVKD, Kratom which suggests it contains Kratom - a tropical evergreen tree often used in traditional medicine, particularly in Southeast Asia, and 7-Hydroxy which is likely referring to 7-hydroxymitragynine, an alkaloid found in the Kratom leaf.
Please note that the use of Kratom can be controversial due to its potential for dependency and addiction. It is advisable to bring this product to your physician's attention before starting its use and make sure of its legality in your area.
