There are no FDA-approved tirzepatide drops. Mounjaro and Zepbound come only as weekly shots under the skin. Products sold as tirzepatide drops, sublingual drops or "GLP-1 herbal oral liquid" are either unapproved compounded products with no trial data, or they contain no tirzepatide at all. Start with our tirzepatide guide if you are new to the drug.
Key takeaways
- The Zepbound and Mounjaro labels list one route: subcutaneous injection, once weekly, in the abdomen, thigh or upper arm.
- No trial in our verified list tested tirzepatide drops, sublingual drops, oral liquid or any product taken by mouth.
- A "herbal" oral liquid cannot contain tirzepatide as an herbal ingredient. Tirzepatide is a synthetic peptide, not a plant extract.
- The FDA warns that unapproved GLP-1 products, including those sold online without a prescription, are not checked for safety, effectiveness or quality.
- Compounded tirzepatide in any form is not FDA approved and is not interchangeable with Zepbound or Mounjaro.
Does Mounjaro come in drops?
No. Eli Lilly sells tirzepatide as Mounjaro and Zepbound, each in a prefilled single-dose pen or a single-dose vial for injection. The prescribing information does not describe a liquid to swallow, a liquid to hold under the tongue, or any product taken by mouth. Tirzepatide is a peptide made of 39 amino acids. Swallowed peptides are broken down by stomach acid and enzymes before they can be absorbed, which is why the approved product is injected.
When people search for "Mounjaro drops" or "tirzepatide drops", they usually mean one of three things. Sometimes it is the small volume of a compounded injection, measured in units on an insulin syringe, which some people call "drops" even though it is injected. Sometimes it is a sublingual product from a compounding pharmacy. And sometimes it is a bottle sold online as a "GLP-1 herbal oral liquid". Only the first one is tirzepatide used the way the label describes.

Some compounding pharmacies prepare tirzepatide in a liquid meant to be held under the tongue. The idea is that the drug crosses the lining of the mouth and skips the stomach. Whether enough tirzepatide crosses that way to matter is a question that only an absorption study can answer, and there is none in the sources we use. That means we cannot tell you a sublingual dose, we cannot tell you how much reaches the blood, and we cannot tell you whether it produces any of the weight loss seen with the injection.
What we can tell you is what the injection did. In SURMOUNT-1, adults with obesity or overweight who used the injection for 72 weeks had a mean weight change of -15.0% at 5 mg, -19.5% at 10 mg and -20.9% at 15 mg, against -3.1% on placebo. Those numbers belong to the injection. A drop that has not been tested has not earned them. Our oral tirzepatide page covers tablets and ODT products the same way.
"Tirzepatide GLP-1 herbal oral liquid": a contradiction in terms
Tirzepatide is not found in any plant. It is a designed molecule made in a laboratory by chemical synthesis. A product labeled "herbal" either does not contain tirzepatide, in which case the name is misleading, or it contains an unapproved drug hidden in a supplement, which is one of the things the FDA's page on unapproved GLP-1 products warns about. Either way, you cannot know what you are taking. If a bottle claims to be both herbal and tirzepatide, that claim alone is a reason not to buy it.
Reviews of tirzepatide drops
Searches for "oral tirzepatide drops reviews" and "tirzepatide sublingual drops reviews" bring up testimonials, not data. A review cannot tell you how much drug was absorbed or whether the person also changed their diet. In SURMOUNT-1, the placebo group lost 3.1% of body weight over 72 weeks while following the trial's lifestyle advice, so weight loss on its own does not prove a product did anything. This page does not print reviews or ratings for that reason.
What the labeled injection looks like in practice
If "drops" appeals to you because injections seem hard, here is what the labeled route involves. The needle is short. The volume is small: at a common compounded concentration of 10 mg/mL, a 2.5 mg dose is 0.25 mL, or 25 units on a U-100 insulin syringe. The concentration on your vial label controls that math, so confirm it with the pharmacy. You inject once a week, any time of day, with or without food, into the abdomen, thigh or upper arm, rotating sites. The Zepbound pen video shows the pen version, and our how to inject with a syringe page covers vials.
What this means for compounded tirzepatide
FormBlends offers compounded tirzepatide for injection only, prepared by state-licensed 503A compounding pharmacies and prescribed by independent clinicians of Recess MD LLC after an online assessment. It does not offer drops, sublingual liquids or oral products, because there is no evidence we can cite that they work. The price is $149 for the first month and $239 a month after, at any dose, with injection supplies included; see pricing or the assessment. Compounded tirzepatide is not FDA approved and is not interchangeable with Zepbound or Mounjaro.
Frequently Asked Questions
Are there tirzepatide drops?
Not approved ones. Mounjaro and Zepbound are injections only. Drops sold as tirzepatide are compounded or unapproved products with no published trial evidence in the sources we use.
Do tirzepatide liquid drops work?
Nobody can say, because no absorption study or clinical trial of tirzepatide drops is in the published record we cite. The weight-loss results people quote come from the injection trials.
What is a tirzepatide GLP-1 herbal oral liquid?
A contradiction. Tirzepatide is a synthetic peptide, not an herb, so a product cannot be both. Such bottles either contain no tirzepatide or contain an undisclosed drug, and the FDA warns against unapproved GLP-1 products sold this way.
Are oral tirzepatide drops reviews reliable?
No. A review cannot show how much drug was absorbed or separate the product from diet changes and placebo effect. The SURMOUNT-1 placebo group lost 3.1% of body weight with no active drug at all.
Why can I not just swallow the injection?
Because tirzepatide is a peptide, and peptides are digested when swallowed. The label describes subcutaneous injection as the only route, and no oral form has been approved.
