Does a prescription mean the product is approved?
The Food and Drug Administration is the US medicines regulator; FDA is its short name.
No. A prescription does not give a compounded product FDA approval (rules checked September 26, 2026).
The FDA has not checked the medicine for safety, quality or whether it works before it is sold.
The same is true when the pharmacy follows the law.
Source AWho makes it, and under which rules?
A pharmacy filling your prescription
Sermorelin acetate is the name of the specific chemical version used in Geref, the old approved medicine. Acetate identifies that version; it is not a second medicine.
Under a reading of the rules as of September 28, 2026, a licensed pharmacy may use this ingredient for a named patient’s prescription.
This conclusion comes from applying general FDA rules. The source review found no FDA document giving permission for sermorelin by name.
The pharmacy needs a valid prescription naming you. The ingredient must have test results in a certificate and be made by a business registered with the FDA. Pharmacy quality standards and all other applicable rules still have to be met; state law can add limits.
503A is the section of federal law for this kind of preparation: a pharmacy makes medicine for a particular patient with a prescription.
A business making medicine in batches
Businesses can instead register with the FDA under section 503B of federal law. They make sterile medicine in batches, using methods meant to keep germs out. The legal name for these businesses is outsourcing facilities. They need not be licensed pharmacies, and they can make batches without prescriptions naming individual patients.
They must follow the manufacturing quality rules used by drug factories, and the FDA inspects them.
As of September 28, 2026, the FDA was still reviewing sermorelin acetate for use by these batch makers.
It is not on the final ingredient list.
While reviewing this ingredient, the FDA says it does not plan to try to stop its use by makers that meet the guidance conditions. Those makers must still follow other rules. This describes how the FDA plans to enforce drug rules; it does not approve the medicine.
What can I ask for?
- Which pharmacy or facility makes and sends it?
- Does the ingredient match the sermorelin acetate used in Geref?
- Is this made for my prescription by a pharmacy, or made in batches by a registered business?
- Which rules apply to this preparation, and what records show you meet them?
- Where can I check the licence or FDA registration?
- Who will explain the medicine’s written instructions and answer my questions?
A name or number alone cannot confirm that an offer meets the law. Take the maker’s name and medicine details to your state pharmacy board.
