Three kinds of product that look alike online

The label and the source matter more than how polished the web page looks.

Rules checked: September 2026.

First kind: an approved medicine

An FDA-approved product has an FDA-reviewed label that sets out its approved use, warnings and other details.

Knowing the ingredient name is not enough. Check the brand and the form, meaning injection versus tablet and the strength on the label, because the approved uses can differ between them.

Second kind: a compounded (made-to-order) medicine

A compounded medicine is prepared for a need that a ready-made product may not meet, but the finished product itself is not FDA-approved.

The usual compounder is an ordinary pharmacy mixing a medicine for a single, named person who holds a prescription. The other kind, an outsourcing facility, is a bigger FDA-registered operation producing germ-free (sterile) medicines by the batch, frequently for clinics and hospitals, and it can work without a prescription made out to you.

If you are offered a compounded medicine, ask which of the two made it and get that maker’s name.

Third kind: a chemical labeled for research

Printing “research use only” on a vial does not turn a chemical into lawful treatment. Once the seller’s page talks up weight, healing or hormones, FDA regards the product as a drug for people, and purchasing it to inject yourself is not a lawful route to care.

A dosing guide, mixing supplies or body-change promises make the real purpose easier to see.

FDA explains the compounding boundary

FDA’s page explains when a pharmacy may make a custom medicine for one patient and when it is simply copying a medicine already sold in pharmacies.

It also explains why “FDA-registered” does not mean FDA approved the finished medicine.
