Every ZENKAI doctor holds active registration with the Federal Council of Medicine (CFM) and with the CRM of the state where they prescribe. No exceptions.
📋

Every evaluation is reviewed in full — not just the flagged fields. Your doctor reads your entire history before prescribing.
📊
Monthly monitoring
Patients are reviewed monthly. Dose adjustments, side effect checks, and progress evaluations are standard protocol — not optional.
