Do not confuse a molecule with a verified medication
The name of an active ingredient does not verify the product in a vial. FDA approval, when it exists, applies to a specific product and indication. A compounded version is not FDA-approved, and a research-labeled product is not approved for human use.
Clinical supervision should include diagnosis, contraindication and interaction review, realistic outcome discussion, a valid prescription, traceable sourcing and follow-up. It cannot make an anonymous or counterfeit product safe.

- What are the important contraindications and stopping rules?
- Which licensed pharmacy will dispense the prescription?
