Compounding means preparing a medicine to fill an individual order, rather than supplying the finished product from a drug company.
The US agency called the Food and Drug Administration is abbreviated FDA.
As of September 26, 2026, it has not approved medicines made to order.
Understand the limits on making a medicine
An approved product may leave a need that a medicine made to order can meet.
Tesamorelin is a biologic: a medicine that needs a separate type of product licence under US law.
Federal rules on compounding prohibit pharmacies from producing their own tesamorelin copies.
Request the product’s exact name. Then ask why that product is being offered.
A research label names a different product
Tesamorelin sold for research, or mixed with another peptide, is not an approved tesamorelin product.
A bottle marked “for research use only” is labelled for research, not for treating a person.
If someone offers you that bottle for treatment, ask for the approved product’s name instead.
A peptide is a chain of protein building blocks. If a proposed product is a blend, ask what each part is and where the evidence for that exact product is.
