Microdosing GLP-1s: Does It Work for Weight Loss?
Can tiny doses of powerful GLP-1 drugs help people lose weight or maintain weight loss? Here’s what an obesity doctor has to say about microdosing GLP-1s.
Zepbound is one of the most effective drugs for weight loss—and the new single-dose vials are making it more affordable. Learn about how much Zepbound costs.
If you’re among the 70% of Americans who have excess weight or are living with obesity, you’ve likely heard a lot about Zepbound® in the last six months. And you might be wondering: If it’s right for me, how much is that gonna cost?
In this post, we’re digging into the details to help you learn what to budget for and how to save on the cost of Zepbound.
Three key takeaways:
Zepbound (tirzepatide) is the newest injectable weight-loss medication and the first “dual agonist” or GLP-1/GIP receptor agonist drug that’s FDA-approved for weight loss.
The FDA approved Zepbound in November 2023 as a treatment to assist chronic weight management in people with a body mass index (BMI) of 30+ or those with BMIs of 27+ who have at least one weight-related health condition (such as high blood pressure, high cholesterol, or type 2 diabetes).
Manufactured by Eli Lilly & Co., Zepbound is a once-weekly injection that starts with an initial dose of 2.5 mg, building to a maximum dose of 15 mg (if clinically needed). Zepbound’s active ingredient, tirzepatide, mimics two naturally occurring gut hormones—glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP)—to help reduce appetite, slow digestion, and tamp down hunger.
While Zepbound can cause mild and serious side effects and isn’t safe for everyone, it has been popular from the jump—in large part because clinical studies have found it highly effective for weight loss.
Zepbound’s clinical results outpace clinical weight loss rates for earlier “single agonist” GLP-1 weight loss medications like Wegovy® and Saxenda®.
In clinical trials, adults with obesity or excess weight (with or without diabetes) who took Zepbound as part of a weight care program experienced statistically significant weight loss compared to those taking placebo. In the latest findings, participants without diabetes who were on the highest doses (10 mg or 15 mg) for 36 weeks lost an average of 20.9% of their body weight.
The retail price may be higher at a given pharmacy, but the list price for Zepbound set by the manufacturer is about $1,060 for a month’s supply (four injector pens of any dosage). That’s roughly $290 less than the list price for a month of Wegovy (semaglutide) or Saxenda (liraglutide), two other brand-name injectable GLP-1 prescription drugs approved for weight loss. (On June 24, Teva Pharmaceuticals, Inc. announced the launch of an authorized generic liraglutide, which may reduce the cost of the drug.)
Zepbound is priced about the same as Mounjaro®, which contains the same active ingredient as Zepbound (tirzepatide) and about $100 more than Ozempic® (semaglutide). Both Mounjaro and Ozempic are FDA-approved for type 2 diabetes but are prescribed off-label for weight loss or obesity care.
Finally, Zepbound is considerably more expensive than older non-GLP-1 weight-loss medications and diabetes drugs prescribed off-label for weight loss. The diabetes drug metformin, for example, typically ranges from $10 to $30 a month, depending on dosage.
Eli Lilly has a cost navigator that you can use to check insurance coverage quickly. However, since Zepbound is relatively new, and your insurance company plan documents may be outdated, you’ll need to call your insurer to determine your coverage. Some plans exclude prescription drugs for weight loss. Other insurers may cover Zepbound but only with prior authorization. If it’s covered, you may still have to pay out-of-pocket until you meet your yearly deductible and co-payments.
Even if Zepbound is not covered under your insurance, if you have commercial insurance and a valid prescription, Eli Lilly’s Zepbound Savings Card may cut your cost to as low as $550 a month for up to a year.
If you have Zepbound insurance coverage, the card can save you even more, pushing costs as low as $25 for a one-month or three-month supply for up to a year.
See if you qualify and check the limitations here. One key exclusion: You can’t use the card if you have state, federal, or government-funded health care, including Medicare or Medicaid.
At the end of August 2024, Lilly introduced single-dose Zepbound vials at a lower list price than its Zepbound injector pens. A four-week supply of the 2.5 mg single-dose Zepbound vials is $399. A four-week supply of 5 mg single-dose vials is $549, which is about what you pay now for the injector pens of this dose if you use the Zepbound savings card.
These come with a few caveats:
Drug discount programs like GoodRx, Drugs.com, and SingleCare may offer coupons or coupon codes that can help trim retail prices or at least bring them closer to the manufacturer’s list price if you don’t have insurance or don’t qualify for the manufacturer’s savings card.
Prices vary among pharmacies. And some offer reduced prices for purchases made in cash without insurance or other discounts. Ask your pharmacist for their best cash price. And don’t be afraid to check chat rooms focused on obesity care or Zepbound cost, such as those on Reddit, for recent price wins from pharmacies in your area.
Zepbound isn’t right for every budget—or everybody.
GLP-1 and GLP-1/GIP medications do have some known potential side effects. The most common are nausea, vomiting, diarrhea, and constipation. More serious but less common side effects include pancreatitis, gallbladder disease, and worsening of diabetic eye disease. Those with a personal or family history of medullary thyroid cancer or multiple endocrine neoplasias should not use them.

If you can’t take—or afford—Zepbound, that doesn’t mean you can’t get weight care. Ask your Found clinician or other trusted health care provider about alternatives that may be a better fit for you—and your insurance coverage.
