Clinician and pharmacy
The service should identify the medical group or clinicians and the dispensing pharmacy. Licensure should be verifiable.
Prescription required
Legitimate U.S. sellers do not ship prescription ED medication without an appropriate prescription.
Truthful approval language
Compounded products should not be described as FDA-approved. Approval of an ingredient is not approval of the combination.
Transparent costs and cancellation
You should be able to identify recurring charges, shipping, quantity, and how to stop refills.
Reachable support
Look for a real address, privacy notice, terms, support channel, and adverse-event process.
