Is sermorelin legal and safe? FDA status explained

Sermorelin is legal to prescribe in the US, and pharmacies compound it today on a clinician's prescription, but no FDA-approved sermorelin product is on the market. It was once approved as Geref, the maker stopped selling it in 2008, and in 2013 FDA said in the Federal Register that the decision was not made for safety or effectiveness reasons. Prescription programs start at $99 a month; see every price.

On safety, the human evidence is modest: a handful of small trials, mostly from the 1990s, plus the old Geref labeling. Here is what each source says and where the gaps are.

Sermorelin was an FDA-approved drug called Geref

Geref (sermorelin acetate) was made by EMD Serono under two applications, according to the 2013 Federal Register notice:

Note what is missing: Geref was never approved for adults, for aging, for sleep or for body composition. Those are the uses most online programs market today, and they are off-label.

Why it disappeared: discontinued in 2008, withdrawn in 2009

The same notice says EMD Serono told FDA it was discontinuing the ampule in a letter dated July 11, 2008, and the vial in a letter dated December 2, 2008, and asked FDA to withdraw both applications. FDA withdrew approval of both, effective June 18, 2009.

The notice does not give the company's business reasons. A 2006 editorial in Clinical Interventions in Aging (Walker, PubMed 18046908) argued that sermorelin "could not compete" with recombinant growth hormone in children. That is one author's view, not an FDA finding.

You can confirm the status on Drugs@FDA, which lists both Geref vial strengths as "Discontinued" and flags a "Federal Register determination that product was not discontinued or withdrawn for safety or effectiveness reasons."

The 2013 Federal Register notice

In October 2012 a citizen petitioner asked FDA whether Geref had been withdrawn for safety or effectiveness reasons. FDA answered in the Federal Register on March 4, 2013. It reviewed its own files, the published literature and postmarketing adverse event data, and concluded that "both GEREF products were not withdrawn from sale for reasons of safety or effectiveness."

The stated purpose of that finding is narrow: it lets FDA approve generic versions (ANDAs) that refer to Geref, if they meet the other legal requirements. FDA also added that it reached the conclusion "based on the information we have at this time." It is not a statement that sermorelin is safe or effective for the adult uses sold online.

Why that matters for compounding (our reading)

Most online sermorelin is made by a 503A compounding pharmacy for an individual prescription. Under section 503A of the Food, Drug, and Cosmetic Act, a pharmacy may compound from a bulk drug substance that has a USP monograph, or, if none exists, one that is a component "of drugs approved by the Secretary," or one on FDA's 503A bulks list. FDA's 503A page describes the same three routes.

Sermorelin is not on the bulks list or in any of FDA's 503A nomination categories. The argument pharmacies rely on is the second route: sermorelin was a component of an approved drug, Geref.

This is our inference, not an FDA statement. We found no FDA page that says in plain words that sermorelin may be compounded. The inference rests on the statute's wording plus the 2013 finding that Geref was not pulled for safety reasons; a product withdrawn for safety reasons would be in a much weaker position. FDA or a court could read "approved" more narrowly, and if that happened, compounded sermorelin programs would likely have to stop.

Some programs say how they compound it. MadeMed's sermorelin page states it is "Prepared exclusively under Section 503A of the Federal Food, Drug, and Cosmetic Act pursuant to a patient-specific prescription." Hone Health's sermorelin page says plainly: "This is a compounded product and has not been approved by the FDA."

What the human evidence shows

The studies are small, short and mostly decades old. The ones we read:

Read together, these show that sermorelin injections raise growth hormone in older adults. They do not show lasting changes in body fat, muscle, sleep or aging. The Vittone authors concluded that single nightly doses "are less effective than multiple daily doses," and Khorram used a modified analog rather than sermorelin itself. The largest adult study here had 19 people. Walker's 2006 editorial, often cited by clinics, is an opinion piece that calls for practitioners to test sermorelin, not a trial.

Common side effects

The old Geref labeling, as summarized by RxList, lists the most common reaction as a local injection reaction ("pain, swelling or redness"), in about 1 patient in 6. Other reactions, each in under 1% of patients, include headache, flushing, trouble swallowing, dizziness, hyperactivity, sleepiness and hives. The labeling also notes that many patients develop antibodies to the drug, and that hypothyroidism occurred in 6.5% of patients in clinical studies, which is one reason thyroid function is worth checking.

In the adult studies above, Vittone reported "no significant adverse effects," and Khorram reported transient high blood lipids that resolved. These trials were too small and short to detect rare or long-term problems.

Prescription sermorelin vs research-use-only vials

Some websites sell sermorelin vials labeled "for research use only." That route skips the clinician and the licensed pharmacy, and nobody checks what is in the vial. FDA has sent warning letters to peptide sellers using such labels, stating that "evidence obtained from your website establishes that your products are intended to be drugs for human use." We do not list these sellers.

A prescription program is no FDA approval either, but it does mean a licensed clinician reviewed your history and a licensed pharmacy made the product for you by name.

FAQ

Is sermorelin legal and safe?

It is legal for a licensed clinician to prescribe and for a 503A pharmacy to compound, based on our reading of the statute and FDA's 2013 Geref finding. Its safety record from the Geref era is fairly clean for short-term use, mostly injection site reactions, but there are no large long-term studies in adults.

Is sermorelin FDA-approved?

Not today. The two Geref products were approved in 1990 and 1997, and FDA withdrew both approvals in 2009 after the maker asked it to. Compounded sermorelin is not an FDA-approved product.

Was sermorelin pulled for safety reasons?

No. FDA's March 2013 Federal Register notice found that both Geref products "were not withdrawn from sale for reasons of safety or effectiveness."

Does sermorelin work for anti-aging?

The human studies show it raises growth hormone in older adults. They do not show lasting changes in body composition, sleep or aging, and the largest adult trial we found had 19 people.

Is research-use-only sermorelin the same thing?

No. Those vials are sold without a prescription or a licensed pharmacy, and FDA has rejected that label in warning letters.
