Quick answer: FDA approved peptides include about 50 active ingredients across more than a dozen drug classes, from insulin’s successors and GLP-1 drugs like semaglutide and tirzepatide to hormone analogs like leuprolide, octreotide, teriparatide, bremelanotide and tesamorelin. The newest on this list are elamipretide (September 19, 2025) and Wegovy tablets (December 22, 2025).[6][7] Popular wellness peptides such as BPC-157, TB-500 and ipamorelin are not FDA approved.

We checked each first-approval year below against Drugs@FDA.[1][2] For how approval differs from compounding, see FDA peptide ban 2026 and the history of peptide regulation. The FDA & Regulation hub has every related guide.

What counts as an “FDA approved peptide”

A peptide is a short chain of amino acids. For regulatory purposes, FDA treats chains of 40 amino acids or fewer as drugs and longer chains as proteins, which have been regulated as biologics since March 23, 2020.[5] We include both short peptides and a few longer peptide hormones that people commonly ask about, and we note when a product is a biologic. Reviews counted more than 80 peptide drugs on the market worldwide by 2021.[3][4]

Years are the first U.S. approval of that brand or ingredient. “Disc.” means Drugs@FDA lists the brand as discontinued; generics may still exist.

Orforglipron (Foundayo), approved April 1, 2026, is an oral GLP-1 drug but a small molecule, not a peptide.[8] See orforglipron.

Insulin analogs such as insulin lispro (Humalog, 1996) and insulin glargine (Lantus, 2000) are peptide hormones of about 51 amino acids. They are now regulated as biologics, so we mention them here but do not list each one.[5]

Patterns in the list

A few trends stand out when you look at FDA approved peptides together.

Most are copies or tweaks of the body’s own hormones. GLP-1 drugs mimic a gut hormone, leuprolide and its relatives mimic gonadotropin-releasing hormone, octreotide mimics somatostatin, and teriparatide is a fragment of parathyroid hormone. Starting from a natural signal gives developers a known target and a known biology.[3]

Chemistry has mostly been about making peptides last longer. Natural peptides break down in minutes. Developers have added fatty acid chains (as in liraglutide and semaglutide), attached polyethylene glycol (as in pegcetacoplan and palopegteriparatide), fused peptides to larger proteins (as in dulaglutide), or used slow-release depots (as in leuprolide and octreotide formulations). These changes are why some products are injected weekly or monthly rather than several times a day.[4]

Oral peptides are still rare. Most peptides are digested in the gut. Rybelsus and Wegovy tablets use an absorption enhancer, linaclotide and plecanatide act inside the gut, and Mycapssa uses a special capsule. Most others are injected, infused or sprayed into the nose.[4]

Approvals are speeding up. About half of the peptide ingredients above were first approved in 2010 or later, led by metabolic and rare-disease drugs.[3]

Notes on biologics and discontinued brands

Two labels in the tables can be confusing. First, a few peptide products, including dulaglutide, tesamorelin and every insulin, carry a biologics license (BLA) rather than a new drug application (NDA). For insulin and tesamorelin, this happened on March 23, 2020, when products with chains longer than 40 amino acids were “deemed to be” biologics licenses.[5] The products themselves did not change, and they remain FDA approved.

Second, “discontinued” in Drugs@FDA usually means the company stopped selling that brand, often for business reasons. It does not by itself mean FDA withdrew the drug for safety. Pramlintide, sermorelin, nesiritide and enfuvirtide are listed as discontinued brands, and some may still be available as other versions. Ask a pharmacist what is currently stocked.[1]

Why most “wellness” peptides are not approved

Since 1962, a drug must be shown to be effective, not just safe, before FDA approves it. That normally means large, controlled human trials for a specific condition. Peptides like BPC-157, TB-500 and epitalon have mostly been studied in animals or in small studies, and no company has completed the trials FDA would need.

Their legal route to patients has instead been compounding, which skips FDA approval. In 2023 FDA placed many of them in Category 2, its list of nominated compounding ingredients with significant safety risks, and in 2026 it removed 12 after their nominations were withdrawn.[9] Neither step says anything about whether they work. See FDA peptide ban 2026 for the details.

Approved vs compounded vs “research” peptides

FDA-approved peptide drugYes: safety, effectiveness and manufacturingSemaglutide (Wegovy)
Compounded peptideNo; pharmacy follows 503A or 503B rulesPatient-specific mixture from a licensed pharmacy
“Research use only” peptideNo; FDA treats many as unapproved new drugsVials sold online with a “not for human use” label

How to check a peptide’s FDA approval yourself

  1. Search the ingredient or brand name in Drugs@FDA. An approved product shows an NDA, ANDA or BLA number and approval history.[1]
  2. For products over 40 amino acids, also check FDA’s Purple Book of licensed biologics.
  3. Read the approved label. The “Indications and Usage” section lists the only uses FDA has approved. Anything else is off-label.
  4. A product with no application number is not FDA approved, whatever its website says.
