Is Sermorelin FDA Approved? The Full Regulatory Story

Sermorelin has a unique regulatory history. It was FDA-approved in 1997 as Geref Diagnostic for testing pituitary function, and its therapeutic form (Geref) was used for pediatric growth hormone deficiency. Then the manufacturer discontinued it in 2008. Today Sermorelin is only available as a compounded medication. Here is the full story.

Is Sermorelin FDA Approved? The Full Regulatory Story

Sermorelin FDA Status at a Glance

Currently FDA Approved?

No. Product discontinued in 2008.

Previously FDA Approved?

Yes. Geref/Geref Diagnostic approved 1997.

Why Discontinued?

Commercial decision by EMD Serono, not safety.

Current Availability

Compounded medication with prescription

Active Molecule

Sermorelin acetate (GHRH 1-29), 29 amino acids

FDA-Approved GH Alternative

Tesamorelin (Egrifta), approved 2010

The Short Answer

Sermorelin was FDA-approved. It is not anymore. The branded product Geref was approved in 1997 and voluntarily discontinued by the manufacturer in 2008. Today Sermorelin is only available as a compounded medication. The molecule itself has the strongest regulatory pedigree of almost any peptide in compounded use, because it actually went through the full FDA approval process and was used clinically for over a decade.

Key Point

Sermorelin's discontinuation was a business decision, not a safety one. No FDA safety warning, recall, or adverse event signal led to its removal from the market. The manufacturer simply chose to stop making it.

The Full Regulatory History

1982

GHRH Discovered

Roger Guillemin's lab at the Salk Institute isolates growth hormone-releasing hormone from a pancreatic tumor. Guillemin had already won the Nobel Prize in 1977 for earlier hypothalamic hormone discoveries.

1997

FDA Approval

The FDA approves sermorelin acetate under two brand names. Geref Diagnostic: for evaluating pituitary growth hormone secretion capacity. Geref: for treating idiopathic growth hormone deficiency in children with open epiphyses. Manufacturer: Serono (later EMD Serono).

2008

Voluntary Discontinuation

EMD Serono discontinues both Geref and Geref Diagnostic for commercial reasons. No safety concerns, no FDA action. Manufacturing simply stops. Sermorelin transitions to compounding pharmacy availability.

1980s

Sermorelin Synthesized

Scientists determine that the first 29 amino acids of GHRH (the 1-29 fragment) retain full biological activity. This fragment is synthesized as sermorelin acetate. Its shorter length makes it easier to manufacture than full-length GHRH (44 amino acids).

1997-2008

Clinical Use

Geref is prescribed for pediatric GH deficiency and used off-label by practitioners for adult GH optimization. Geref Diagnostic is used in endocrinology clinics to test pituitary function. Safety profile is well established over a decade of clinical use.

2008-Present

Compounded Era

Sermorelin becomes one of the most widely compounded peptides in the United States. Licensed pharmacies prepare it under 503A and 503B regulations. The molecule and its effects are well characterized from its FDA-approved years.

Why Geref Was Discontinued

Drug discontinuation for commercial reasons is more common than most patients realize. A pharmaceutical company may stop manufacturing a drug because the market is too small, a newer product replaces it in their portfolio, manufacturing costs increase, or strategic priorities shift after a merger or acquisition.

In Sermorelin's case, EMD Serono was shifting its focus toward other therapeutic areas. The pediatric GH deficiency market was relatively small, and practitioners were increasingly using Sermorelin off-label for adult applications that Serono had no financial incentive to support. The company made a business decision to allocate manufacturing capacity elsewhere.

Importantly, there was no FDA safety warning, no black box update, no recall, and no adverse event signal that prompted the discontinuation. The FDA did not pull Sermorelin from the market. The manufacturer chose to stop selling it. This is a critical distinction that gets lost in casual conversations about the drug's regulatory status.

Sermorelin Today: Compounded Medication

When a previously FDA-approved drug is discontinued and no generic equivalent exists, compounding pharmacies can legally prepare it under federal law. This is exactly what happened with Sermorelin. The molecule, its dosing, its effects, and its safety profile are all well characterized from years of FDA-approved use. The only thing that changed is who manufactures it.

Compounded sermorelin uses the same active molecule: sermorelin acetate, the 29-amino-acid GHRH fragment. It is prepared by licensed 503A or 503B pharmacies, prescribed by licensed providers, and subject to state and federal pharmacy regulations. PeRx ships sermorelin fully reconstituted and ready to use.

Sermorelin's Advantage

Among compounded peptides, Sermorelin has the strongest regulatory history. It is the only widely used compounded peptide that actually went through the full FDA approval process, was commercially manufactured, and was prescribed clinically for over a decade before being discontinued.

Frequently Asked Questions

It was. Sermorelin was approved in 1997 as Geref and Geref Diagnostic. The manufacturer voluntarily discontinued it in 2008 for commercial reasons. Today it is available only as a compounded medication.
EMD Serono stopped manufacturing Geref for business reasons, not safety concerns. There was no FDA recall, no safety warning, and no adverse event signal. The company shifted its priorities to other products.
Sermorelin has the most established safety profile of any compounded peptide because it was used clinically for over a decade as an FDA-approved product. The known side effects are mild: injection site reactions, flushing, and occasional headache. As with any medical therapy, use should be supervised by a licensed provider.
Both are GHRH analogs that stimulate natural growth hormone release. Tesamorelin has a modified N-terminal (trans-3-hexenoic acid group) that protects it from DPP-IV degradation, giving it a longer functional half-life. Tesamorelin is the only currently FDA-approved GHRH analog. Sermorelin is shorter-acting and available only as compounded.
PeRx ships Sermorelin fully reconstituted and ready to use. Store refrigerated at 36-46°F (2-8°C). Do not freeze. Keep the vial upright and away from light.
