Is sermorelin legal, and how is it prescribed?

Yes, sermorelin is legal in the US with a prescription. It is one of the few peptides sold online that a licensed pharmacy may lawfully compound, because the FDA once approved it as a drug called Geref and later found that Geref wasn’t pulled for safety reasons. It is still a compounded, off-label treatment for most people who take it, so the prescription and the pharmacy matter. Here is how that works, and what happens when you get it online.

Why sermorelin is legal to compound

It was an FDA-approved drug

The FDA approved sermorelin acetate twice under the name Geref, made by EMD Serono (Federal Register):

• On December 28, 1990, as an injection for testing whether the pituitary gland can release growth hormone (NDA 19-863).
• On September 26, 1997, as vials for treating idiopathic growth hormone deficiency in children with growth failure (NDA 20-443).

EMD Serono discontinued both products in 2008, and the FDA withdrew their approvals effective June 18, 2009. On March 4, 2013, after reviewing a citizen petition, its own records and the published data, the FDA determined that both were “not withdrawn for reasons of safety or effectiveness.”

That keeps it eligible under section 503A

A 503A compounding pharmacy may prepare a medicine for one patient’s prescription from a bulk ingredient that has a USP monograph, is a component of an FDA-approved drug, or is on the FDA’s bulks list (FDA interim policy). Sermorelin qualifies as a component of an approved drug. And because the FDA found that Geref wasn’t withdrawn for safety or effectiveness, sermorelin isn’t barred the way a drug pulled for safety reasons would be.

The FDA hasn’t published a statement specific to compounding sermorelin, and it doesn’t appear on the FDA’s compounding safety-risks page (FDA).

It isn’t a controlled substance

Sermorelin is not on the DEA’s list of controlled substances (DEA). Unlike testosterone, a Schedule III drug, it has no special rules for telehealth prescribing beyond the usual need for a valid prescription.

Legal isn’t the same as approved

Two limits apply to every sermorelin prescription you can get today.

It is compounded. No approved sermorelin product is on the market, so every vial, nasal spray or tablet comes from a compounding pharmacy. Compounded sermorelin is not FDA-approved, and the FDA does not review compounded medicines for safety, effectiveness or quality before they are sold.

It is off-label for adults. Geref was approved for children with growth hormone deficiency and for a diagnostic test. Online providers prescribe sermorelin to adults for energy, sleep, recovery or body composition. Those uses were never part of an FDA approval, so the evidence behind them is limited. A clinician can prescribe off-label when they judge it appropriate for you.

How sermorelin is prescribed online

The steps are similar across the providers we track, but how much testing and contact you get varies.

1. Online intake. You fill in a health questionnaire. PepScribe’s takes about 3 minutes; Maximus says about 5.
2. Clinician review. A licensed clinician reviews it and decides whether to prescribe. At PepScribe a US-licensed clinician reviews it within about 24 hours, with a video or audio visit where state law requires one. Hone Health requires a $65 biomarker blood test and a 1:1 video consult with a physician before prescribing.
3. Prescription to a pharmacy. If you are approved, the prescription goes to a licensed compounding pharmacy. PepScribe names its three 503A pharmacies with their NPI numbers; most providers we track don’t name theirs.
4. Delivery. The medication ships to you. Most kits include syringes and alcohol pads. Maximus sends pre-filled vials, so there’s nothing to mix.
5. Follow-up. You can message the care team about side effects or dose changes. Some providers offer IGF-1 blood tests to track your response.

Forms you can be prescribed

• Nightly injection under the skin. This is the most common form, at PepScribe, AgelessRx, Maximus, Hone and Eden.
• Nasal spray, at AgelessRx and Valhalla Vitality.
• Dissolving tablets or troches, at Eden (sermorelin ODT) and Valhalla Vitality.

What it costs

These are the published prices on each provider’s own site, as of October 2026. Our sermorelin cost guide works out what each plan costs over six months.

What a prescription usually looks like

The clinician sets your dose, but the providers we track describe similar routines. PepScribe prescribes one small injection under the skin each night before bed, timed to the body’s natural overnight release of growth hormone. Maximus’s standard dose is 1 mg five days a week, from a 10 mL vial that it says lasts 28 days, with lower doses in California. Expect to wait: PepScribe says most people judge sleep and recovery over the first one to three months, and Hone Health says effects are usually felt in 2 to 6 months.

Some providers track your response with blood tests. Maximus offers IGF-1 tests before and after through its own lab service, and Hone retests biomarkers every 6 months on its Basic tier. If your provider doesn’t offer follow-up labs, ask how it will judge whether the dose is right.

Who should be careful

Sermorelin raises your body’s own growth hormone, so it isn’t for everyone. Hone Health’s sermorelin page, for example, says men with a history of epilepsy, untreated hypothyroidism or high blood sugar should avoid it, and warns that it may worsen insulin resistance or cause fluid retention and joint pain. It also flags a history of cancer or diabetes as reasons to talk to a clinician first. Tell the reviewing clinician about every condition and medication, and ask how they will follow up.

Red flags when you shop

• No clinician review. A legitimate provider has a licensed clinician decide, and doesn’t let you pick sermorelin off a menu without one.
• Stacks with peptides pharmacies can’t make. Sermorelin is often sold online alongside CJC-1295 or ipamorelin. Neither may be compounded by a 503A pharmacy, and the FDA reports serious adverse events with both.
• Vials labeled for research only. These aren’t prescriptions. Buying them for personal use is unsafe and unregulated, because no one checks what’s in them.
• No pharmacy you can verify. Ask which pharmacy will fill your prescription, and check its license with your state board of pharmacy.

The bottom line

Sermorelin is legal with a prescription, because its approved form, Geref, left the market for reasons other than safety. That lets licensed pharmacies compound it, but it doesn’t make compounded sermorelin FDA-approved, and most adult uses are off-label. If you want to try it, use a licensed provider that names its pharmacy and has a clinician review your history.
