A word with a legal effect
Biologic
“Biologic” is the legal name for a group of medicines that includes tesamorelin and insulin.
For tesamorelin, the key point is that pharmacies cannot legally make their own copies.
- Biologics licence
- Permission from the U.S. Food and Drug Administration (FDA) for a company to sell a biologic medicine.
Where tesamorelin fits
As of September 28, 2026, U.S. law treats tesamorelin as a biologic.
On March 23, 2020, tesamorelin’s existing FDA approval became a biologics licence. This changed the legal rules that apply to the medicine.
Tesamorelin is made in a laboratory, even though the law groups it with biologic medicines.
- Compounding
- Preparing medicine for one patient’s needs instead of using a finished product.
What this means for a pharmacy copy
As of September 26, 2026, federal rules that let some drugs be compounded do not cover biologic products.
A company needs FDA approval through a biologics licence before it can sell one of these medicines.
Making a tesamorelin copy for use in patient care is not legal for a pharmacy.
- A useful question
- Which approved product is being discussed?
Ask for the full name
Ask whether the offer is for tesamorelin (EGRIFTA SV or EGRIFTA WR).
If a service instead describes a custom pharmacy blend, ask it to explain the product’s status.
Keep that answer separate from a discussion of price.
