Do GLP-1 patches, drops and supplements work? What the FDA and FTC say
What these products are, the only forms FDA-approved GLP-1 medicines come in, the warnings regulators have issued, and how to report a product.
Written for the United States. Other country versions are coming.
No. No patch, drop or supplement contains an FDA-approved GLP-1 medicine. Every approved GLP-1 is a prescription injection or tablet. The FTC says nothing you wear or rub on your skin will make you lose weight. The FDA has warned about "GLP-1" drops falsely sold as approved, and slimming products hiding drugs.
Key takeaways
- Every FDA-approved GLP-1 medicine is a prescription injection under the skin or a tablet; FDA’s approved-drug records list no patch, drop, spray or gummy.1
- The Federal Trade Commission says, “Nothing you can wear or apply to your skin will cause you to lose weight. Period.”2
- A 2026 pharmacy-school review found 24 “natural GLP-1” patches and 1 gel with about 7 ingredients each and no posted lab certificates; US law says supplements must be swallowed.3,4
- In December 2024 the FDA warned a seller of “GLP-1” drops that falsely claimed FDA approval and promised up to 52 pounds lost in 3 months.5
- The FDA has warned firms selling semaglutide, tirzepatide and retatrutide labeled “for research purposes”; retatrutide is not in any FDA-approved drug.6

What are “GLP‑1” patches, drops and supplements?
They are products sold online and in stores that use the name “GLP‑1” but are not GLP‑1 medicines. They come in forms no approved GLP‑1 takes.1,3,5
- Approved GLP‑1 medicines are prescription-only in the US.1
- We describe types of product and what regulators said about them. We name no brand, seller or website.
- Nothing here is a reason to start or stop a medicine on your own.
- Every risk of the approved medicines is in our side-effects guide.
The types regulators and researchers have described:
- Skin patches and gels sold as “natural GLP‑1”, often with plant extracts such as berberine, cinnamon or pomegranate.3
- Drops and liquids said to work like GLP‑1 medicines, sometimes with false claims of FDA approval.5
- Capsules and gummies sold as dietary supplements that “support” GLP‑1.7,8
- “Research” vials of semaglutide, tirzepatide or unapproved peptides, labeled “not for human consumption” but sold with dosing instructions.6
The 2026 review notes who these products reach: people who can’t get semaglutide or tirzepatide from a clinician or their insurer.3
What forms do FDA-approved GLP‑1 medicines come in?
Only two: an injection under the skin, or a tablet you swallow. All of them need a prescription.1
- Injections: Wegovy, Ozempic, Zepbound, Mounjaro, Saxenda, Victoza, Trulicity and generic liraglutide.1
- Tablets: Wegovy tablets, Ozempic tablets, Rybelsus and Foundayo.1
Semaglutide is a copy of a gut hormone, GLP‑1, built to last longer: the Wegovy label says its building blocks (amino-acid sequence) are 94% the same as the natural hormone’s.9 Even as a tablet it needs care. The Wegovy label says to take it on an empty stomach with up to 4 ounces of water. Then wait at least 30 minutes before eating or drinking.9

Can a patch or skin gel work like a GLP‑1?
No. The FTC lists “Lose weight with this patch or cream” among false weight-loss claims, and adds: “(You can’t.)”2
A 2026 review by University of Connecticut pharmacy researchers looked at “natural GLP‑1” skin products sold in the US. It found:3
- 24 patches and 1 gel, with an average of 7 plant or nutrient ingredients each
- no certificates of analysis (independent lab results) posted for any of them
- many without the disclaimer the FDA requires on supplement claims
- many using deceptive advertising
- reviews of 1 or 2 stars on several, with comments suggesting they didn’t work or caused side effects
The review’s title calls them illegal. The reason is the law’s definition: a dietary supplement must be “intended for ingestion”, meaning swallowed. A patch on the skin isn’t.3,4
What about “GLP‑1” supplements and drops?
The FDA does not check supplements before they go on sale, and none is a GLP‑1 medicine. The FDA says it has no authority to approve supplements for safety or effectiveness first.7
- “Supports GLP‑1” is a structure/function claim. The FDA doesn’t approve these claims. The label must say: “This statement has not been evaluated by the Food and Drug Administration.”8
- Claims to treat a disease make it a drug. The FDA says a product meant to treat, prevent or cure a disease is a drug under the law.7
- False approval claims: in December 2024 the FDA warned an online seller of drops that cited “the science of GLP‑1”. The FDA called them unapproved and misbranded drugs, partly for an “FDA approved” claim.5
Is berberine “nature’s Ozempic”?
Berberine, a plant extract, is a common ingredient in these products.3 NIH’s complementary health center says some studies suggest it might help weight loss, but “the evidence is not conclusive.”10
- The evidence: a 2022 review found lower weight mainly at doses over 1 gram a day for more than 8 weeks. Many of its studies had a high risk of bias.10
- The harms: nausea, stomach pain, bloating, constipation or diarrhea. It interacts with cyclosporine, a transplant drug, and may be unsafe in pregnancy or breastfeeding.10
Hidden drugs
The FDA says it has found more than 1,000 fraudulent health products, some hiding prescription drug ingredients.11 In September 2026 it warned that a weight-loss product sold online contained sibutramine, a drug taken off the market for safety reasons. Sibutramine can sharply raise blood pressure or heart rate.12

What are “research use only” GLP‑1s?
They are unapproved drugs sold as lab chemicals. The FDA has warned companies selling semaglutide, tirzepatide, retatrutide and similar peptides “falsely labeled ‘for research purposes’ or ‘not for human consumption’.”6
- Sold for human use: the FDA says these products have been sold directly to consumers, with dosing instructions.6
- Retatrutide is not approved: the FDA says it is not in any FDA-approved drug and has not been found safe and effective. It can’t be used in compounding either.6
- Fakes: the FDA warns that illegally sold drugs may be counterfeit, with too little, too much or none of the active ingredient, or harmful ones.6
Our posts on counterfeit Ozempic and compounded GLP‑1s cover the related risks.
How can you spot a fake GLP‑1 product?
Watch for the wrong form, no prescription, an approval claim on a supplement, or a promise that sounds too easy. Each one is a sign the product is not an approved GLP‑1.1,2,7
- No prescription needed: every approved GLP‑1 is prescription-only.1
- Wrong form: a patch, drop, spray, gummy or cream. Approved GLP‑1s are injections or tablets.1
- “FDA approved” on a supplement: the FDA can’t approve supplements before sale.7
- Too-easy promises: the FTC flags claims such as losing weight without diet or exercise, 30 pounds in 30 days, or a product that “works for everyone”.2
- “For research use only” on something sold to you with dosing advice.6
What should you do if you used one?
Report it. The FDA takes reports through MedWatch, and the FTC takes reports of false advertising.2,13
- Side effects or a bad product: FDA MedWatch, online, or at 1-800-FDA-1088, the number on the Wegovy label.9,13 Our how to report a side effect answer walks through it.
- False claims or a scam: ReportFraud.ftc.gov, or your state attorney general.2
- Tell whoever treats you what you took. The FDA warns that hidden ingredients can interact with other medicines.12
- Hidden drugs: the FDA has found slimming products containing sibutramine, which can sharply raise blood pressure or heart rate.12
- Wrong dose or wrong ingredient: the FDA warns illegally sold GLP‑1s may contain too much, too little or none of the active ingredient.6
- Approved GLP‑1s have risks too: mainly stomach effects, plus label warnings on pancreatitis, gallbladder problems and thyroid tumors in rodents.9
Questions people ask
Do GLP-1 patches work?
The FTC says nothing you wear or apply to your skin will cause you to lose weight. A 2026 review of 25 “natural GLP-1” skin products found no posted lab results for any of them.2,3
Are GLP-1 drops FDA approved?
No. FDA-approved GLP-1 medicines are injections or tablets only. In 2024 the FDA warned a seller of drops that falsely claimed approval.1,5
Is berberine nature’s Ozempic?
No. Berberine is a plant extract, not a GLP-1 medicine. NIH says the evidence that it helps weight loss is not conclusive.10
Can you get a GLP-1 without a prescription?
Not an FDA-approved one. Every approved GLP-1 medicine is prescription-only in the US.1
Is retatrutide approved?
No. The FDA says retatrutide is not in any FDA-approved drug and has not been found safe and effective for any condition.6
How we researched this
On October 14, 2026, we searched FDA’s approved-drug records for every GLP‑1 medicine and its dosage forms. We read the FDA’s pages on unapproved GLP‑1s, dietary supplements, supplement claims and health fraud.
We also read one FDA warning letter, one FDA public notice, the FTC’s weight-loss advice and the federal definition of a dietary supplement. Then NIH’s berberine page, a 2026 review of skin products and the current US Wegovy label.
We name no product, brand or seller of an unapproved product, and we link to no shop. Regulators’ own pages name the companies they warned.
Before you move on
- No patch, drop or supplement contains an FDA-approved GLP‑1.
- Approved GLP‑1s are prescription injections or tablets.
- “FDA approved” on a supplement is a red flag.
- Report problems to FDA MedWatch and false claims to the FTC.
