Sermorelin: what it is, who prescribes it and what it costs

Sermorelin is a short synthetic peptide that copies the active part of the body's growth hormone releasing hormone (GHRH), so it prompts the pituitary to release your own growth hormone. It is not FDA-approved today: it is compounded by licensed pharmacies on a clinician's prescription. Online programs start at $94 a month; see every sermorelin price.

Below: what sermorelin is, what "sermorelin acetate" means, its FDA status, who prescribes it, the forms programs sell, and what the evidence in people does and does not show.

What is sermorelin?

A 1999 drug review in BioDrugs describes sermorelin as "a 29 amino acid analogue of human growth hormone-releasing hormone (GHRH)" and "the shortest synthetic peptide with full biological activity of GHRH" (Prakash and Goa, PubMed 18031173). The natural hormone is longer; sermorelin keeps the first 29 building blocks, the part that does the signalling.

The key difference from growth hormone itself: sermorelin does not replace growth hormone, it asks the pituitary to release more of it. The same review says it can "specifically stimulate growth hormone secretion from the anterior pituitary" (Prakash and Goa). That means it only works if the pituitary can still respond, which is why it was once used as a diagnostic test of pituitary function.

Providers describe it the same way. Luvo Health's page lists the active ingredient as sermorelin acetate and notes that "Compounded medications are not FDA-approved" (Luvo Health). Hone Health calls it "a synthetic peptide that stimulates the release of growth hormone from the pituitary gland" (Hone Health).

Sermorelin, sermorelin peptide, sermorelin acetate: one drug

People search for "sermorelin peptide", "sermorelin injections" and "sermorelin acetate" as if they were three things. They are one drug:

Drugs@FDA lists the former brand, Geref, with the active ingredient "SERMORELIN ACETATE". Online programs compound the same ingredient.

Is sermorelin FDA-approved?

No, not today. Sermorelin was approved as Geref (EMD Serono) for diagnosing pituitary function and for growth hormone deficiency in children. The maker stopped selling it in 2008 and FDA withdrew the approvals in 2009. In a 2013 notice, FDA concluded that "both GEREF products were not withdrawn from sale for reasons of safety or effectiveness" (Federal Register, March 4, 2013). Drugs@FDA still marks both vials as "Discontinued" with a "Federal Register determination that product was not discontinued or withdrawn for safety or effectiveness reasons" (Drugs@FDA, NDA 020443).

Its compounding status, stated plainly:

The route pharmacies rely on is the second of the three on FDA's 503A page, substances that "Are components of FDA-approved drug products if an applicable USP or NF monograph does not exist" (FDA 503A page). That reading is ours, not an FDA statement, and it rests on Geref having been approved. Our FDA status guide walks through the argument and where it could be challenged.

Who prescribes sermorelin?

A licensed clinician, usually through a telehealth program, after an online intake. A pharmacy then compounds it for you by name. Hone Health states that "Prescription products require an online consultation with a healthcare provider who will determine if a prescription is appropriate" (Hone Health). System Labs says its therapies "may include medications compounded by a state-licensed pharmacy" (System Labs). MadeMed says its sermorelin is "Prepared exclusively under Section 503A of the Federal Food, Drug, and Cosmetic Act pursuant to a patient-specific prescription" (MadeMed).

What the programs differ on is how much oversight comes with the prescription. Hone Health builds lab testing into a membership; most cheaper programs do not mention labs. Few programs name their pharmacy. MYRNK is one that lists a pharmacy address on its own page, in Springville, Utah (MYRNK). The best programs page scores each one on care, transparency and price.

Sites that sell sermorelin labeled "research use only" skip the clinician and the licensed pharmacy. FDA treats those products as unapproved drugs, and we do not list them.

Forms: injections, tablets and sprays

Most programs sell sermorelin as an injection under the skin, which is the form used in the published studies. Some also sell an oral dissolving tablet. System Labs says its injection and tablet "contain clinical-grade sermorelin from the same U.S. pharmacies" (System Labs). We found no published human trial of oral or nasal sermorelin, so a tablet's lower price does not show it works like the injection. Your prescriber sets the form and the amount; we do not publish doses.

What sermorelin costs

Programs price sermorelin by plan length: month to month costs the most, and 6- or 12-month prepaid plans the least per month. The cheapest program today is Idun Rx at $94 a month (Sermorelin, 12 months, 12-month plan, listed per month (upfront billing not stated)). No program we track bills insurance. Our sermorelin cost guide breaks down each plan, fee and refund policy, and the price table is updated from the providers' own pages.

What the evidence shows, and where it is thin

The strongest data is from children with growth hormone deficiency, the use Geref was approved for. The BioDrugs review found that "Significant increases in height velocity were sustained during 12 months' treatment with sermorelin" (Prakash and Goa). A 110-child trial reported that "overall GHRH was well tolerated" (Thorner 1996, PubMed 8772599).

For adults, which is who online programs serve, the trials are small. In 11 men aged 64 to 76 given nightly injections for 6 weeks, the authors concluded that single nightly doses "are less effective than multiple daily doses" (Vittone 1997, PubMed 9005976). We found no large, long-term trial in adults showing lasting effects on body fat, muscle, sleep or aging. Marketing claims about those outcomes go further than the studies.

Side effects and who should be careful

In the review, "Transient facial flushing and pain at injection site were the most commonly reported adverse events" (Prakash and Goa). Hone Health's page adds that "Sermorelin may worsen insulin resistance or contribute to fluid retention and joint pain" and lists cancer history, diabetes and untreated thyroid disorders as reasons for caution (Hone Health). Tell the prescriber about any of these before starting.

Sermorelin vs tesamorelin: the approved cousin

Tesamorelin is another GHRH analog, and unlike sermorelin it is FDA-approved as Egrifta. Its label is narrow: "a growth hormone-releasing factor (GHRF) analog indicated for the reduction of excess abdominal fat in HIV-infected adult patients with lipodystrophy" and "Not indicated for weight loss management" (DailyMed, Egrifta WR). Sermorelin has no current approved use at all; every adult use sold online is off-label.

FAQ

Sermorelin: what is it, who prescribes it and what does it cost?

Sermorelin is a synthetic copy of the first 29 amino acids of growth hormone releasing hormone, which prompts the pituitary to release growth hormone. A licensed clinician prescribes it, usually through a telehealth intake, and a 503A pharmacy compounds it. Prices start at $94 a month, with the lowest rates on prepaid plans; our price table lists every program.

What is sermorelin acetate?

Sermorelin acetate is the salt form of sermorelin used in the medicine. Geref, the former FDA-approved brand, listed sermorelin acetate as its active ingredient, and compounding pharmacies use the same ingredient today. When a program says sermorelin, sermorelin acetate or sermorelin peptide, it means the same drug, so compare programs on price, pharmacy and oversight rather than on the name.

Is sermorelin a peptide or a hormone?

Both descriptions fit in part. Sermorelin is a peptide, a chain of 29 amino acids, and it copies part of a hormone, GHRH. Sermorelin is not growth hormone itself: it signals the pituitary to release growth hormone, so the effect depends on the pituitary still working. That is the main difference from prescription growth hormone, which supplies the hormone directly.

Is sermorelin legal to get online?

Yes, with a prescription. A licensed clinician must review your history, and a licensed pharmacy compounds the medicine for you by name. Sermorelin is not FDA-approved today and is not on FDA's category 2 list. Products sold as "research use only" without a prescription are a different thing: FDA treats them as unapproved drugs, and we do not list those sellers.

Does insurance cover sermorelin?

Generally no. Compounded sermorelin is not an FDA-approved product, and none of the programs we track bills insurance, so expect to pay cash. One program, MadeMed, lists itself as HSA and FSA eligible on its page, which may let you pay with pre-tax money. Check with your plan administrator before relying on that.

How long does sermorelin take to work?

Programs give their own timelines, often a few months, but these are marketing estimates rather than trial results. The adult trials we read, listed in our FDA status guide, lasted from 2 to 16 weeks, showed rises in growth hormone, and found little lasting change in body composition or sleep. A prescriber who orders follow-up labs can tell you whether your levels changed.
