As of September 28, 2026, US law puts tesamorelin in a group of medicines called biologics. This group needs a separate type of product licence.
Tesamorelin is still made in a lab; the category does not change that.
What this means for a pharmacy-made medicine
Compounding is preparing a medicine for an individual order.
Pharmacies cannot make a biologic under the compounding rules, says the US Food and Drug Administration (FDA).
The rules for making medicines to order do not replace the separate product licence needed for a biologic.
Use the category to ask a concrete question
A pharmacy-made tesamorelin copy is not a lawful replacement for the approved medicine.
Ask for the exact product name, rather than accepting an answer that it is “the same ingredient.” Keep the written name so you can ask the doctor prescribing it to explain it.
