I'm sorry, but it appears that there's no specific information available online regarding the MODUS 7-HYDROXY 4CT 20MG TABLETS. It should be noted that 7-Hydroxy is often related to 7-Hydroxymitragynine, which is a potent partial opioid agonist (can act like an opioid) found in the Mitragyna speciosa kratom plant. Please make sure you consult with a healthcare professional before using such substances. Also, remember that unregulated substances carry additional risks including lack of standardization and potential legality issues.
