Cost & Pricing
How much do GLP-1 medications cost without insurance?
List prices are high: Novo Nordisk lists Wegovy at $1,349.02 per package and Ozempic at $997.58. Few self-pay patients pay that. As of November 4, 2026, manufacturer self-pay prices are $149 to $299/mo for the Wegovy pill, $349/mo for the Wegovy pen, $299 to $449/mo for Zepbound vials and KwikPens, and $499/mo for Mounjaro pens. Novo will cut Wegovy and Ozempic list prices to $675/mo from January 1, 2027. Source: NovoCare Wegovy pricing.
Full cost breakdown →What is the cheapest way to get GLP-1 medications online?
The cheapest FDA-approved self-pay option we found is the Wegovy pill at $149/mo for the 1.5 mg dose through NovoCare (checked November 4, 2026). Compounded semaglutide is often advertised for less, but it is not FDA-approved. With commercial coverage, manufacturer savings cards can bring Wegovy or Zepbound to as little as $25. Source: NovoCare Wegovy pricing.
Full pricing comparison →Does insurance cover Wegovy or Mounjaro for weight loss?
Some commercial plans cover Wegovy or Zepbound (both FDA-approved for chronic weight management), usually with prior authorization. Mounjaro is approved for type 2 diabetes, so plans usually cover it only for that diagnosis. Coverage varies widely by plan. Source: Mounjaro prescribing information.
Insurance coverage guide →Does Medicare cover GLP-1 medications in 2026?
Standard Medicare Part D still excludes drugs used only for weight loss. From July 1, 2026 to December 31, 2027, CMS runs the temporary Medicare GLP-1 Bridge, which gives eligible Part D beneficiaries certain GLP-1 drugs for a $50 copay. There is no low-income subsidy on that copay. Part D can cover GLP-1s for other approved uses such as type 2 diabetes. Source: CMS Medicare GLP-1 Bridge.
Medicare coverage details →Can I use HSA or FSA to pay for GLP-1 medications?
Usually. IRS rules treat prescribed drugs as qualified medical expenses, and Lilly's self-pay pages say LillyDirect purchases are FSA/HSA eligible, though eligibility may vary by plan. Check with your plan administrator before you pay. Source: IRS Publication 502.
HSA/FSA-eligible providers →Medications & Comparisons
Is Mounjaro or Ozempic better for weight loss?
Tirzepatide (the drug in Mounjaro and Zepbound) produced more weight loss than semaglutide (the drug in Ozempic and Wegovy) in the SURMOUNT-5 head-to-head trial in adults with obesity and without diabetes. Mean weight change at 72 weeks was 20.2% with tirzepatide and 13.7% with semaglutide (NEJM, 2025). Which drug suits you is a decision for you and your prescriber. Source: SURMOUNT-5 on PubMed.
Full Mounjaro vs Ozempic comparison →What is the difference between Mounjaro and Zepbound?
Mounjaro and Zepbound are the same molecule (tirzepatide) made by Eli Lilly. Mounjaro is FDA-approved for type 2 diabetes. Zepbound is approved for chronic weight management and for obstructive sleep apnea with obesity. The labels, insurance pathways and self-pay prices differ. Source: Zepbound prescribing information.
Mounjaro vs Zepbound details →What is the difference between Ozempic and Wegovy?
Both are semaglutide made by Novo Nordisk. Ozempic is FDA-approved for type 2 diabetes, with a top dose of 2 mg weekly. Wegovy is approved for chronic weight management with a 2.4 mg maintenance dose, and Wegovy HD 7.2 mg was approved in March 2026. Insurance pathways and prices differ. Source: Wegovy label.
Ozempic vs Wegovy comparison →What is compounded semaglutide?
It is a drug made by a compounding pharmacy (503A) or outsourcing facility (503B) that is marketed as containing semaglutide. It is not FDA-approved and is not a generic Ozempic or Wegovy. FDA resolved the semaglutide shortage on February 21, 2025, and the grace periods for making copies ended in 2025. FDA says compounded drugs should be used only when an approved drug cannot meet a patient's needs. Source: FDA compounding policy.
Compounded semaglutide guide →Is the Wegovy pill as effective as the Wegovy injection?
They were tested in separate trials, so there is no direct head-to-head answer here. Injectable Wegovy produced 14.9% mean weight loss at 68 weeks in STEP 1 (NEJM, 2021). The Wegovy pill (up to 25 mg daily) was approved in December 2025. It costs $149 to $299/mo self-pay through NovoCare and must be taken on an empty stomach as the label directs. Source: STEP 1 on PubMed.
Pill vs injection comparison →Side Effects
What are the most common GLP-1 side effects?
The FDA labels list nausea, diarrhea, vomiting and constipation among the most common side effects. They are more frequent when starting or increasing a dose. In SURMOUNT-1, adverse events led to stopping treatment in 4.3%, 7.1% and 6.2% of people on 5 mg, 10 mg and 15 mg tirzepatide, against 2.6% on placebo. Tell your prescriber about severe stomach pain or vomiting. Source: SURMOUNT-1 on PubMed.
Month-by-month side effect guide →How long do GLP-1 side effects last?
Stomach side effects are usually most noticeable after starting the drug or raising the dose, and for many people they ease over the following weeks. Experiences vary. If side effects do not settle, your prescriber may slow or pause dose increases. Source: Zepbound prescribing information.
Side effect timeline →Is tirzepatide or semaglutide easier on the stomach?
In SURMOUNT-5, gastrointestinal events were the most common adverse events with both drugs, and most were mild to moderate. Individual responses vary a lot, so this is not a reason on its own to pick one drug. Source: SURMOUNT-5 on PubMed.
Side effect comparison →Body Composition & Exercise
How much muscle do you lose on GLP-1 medications?
Body composition substudies of the main trials found that lean mass made up part of the total weight lost, with fat making up most of it. Resistance training and enough protein can help limit lean mass loss. Ask your clinician or a dietitian for a protein target that fits your kidneys and health. Source: SURMOUNT-1 on PubMed.
Exercise and muscle preservation guide →Should I exercise while on GLP-1 medication?
Yes, if your clinician agrees. The FDA labels pair these drugs with a reduced-calorie diet and more physical activity. Resistance training a few days a week is a common way to protect lean mass while losing weight. Source: Zepbound prescribing information.
Exercise strategy on GLP-1s →Is a DEXA scan worth it while on GLP-1 medications?
A DEXA scan estimates fat mass and lean mass separately, which a bathroom scale cannot do. That can help if you want to track how much of your weight loss is fat. Prices vary by imaging center, so ask for a quote.
Real DEXA scan results on Mounjaro →What should I do if I hit a weight loss plateau on Mounjaro?
Check your trend over several weeks rather than day to day. Review your eating and activity with your clinician, and keep up resistance training. Any dose change is a decision for your prescriber.
Plateau-breaking strategies →Dosing & Titration
What is the Mounjaro dosing schedule?
Per the label, Mounjaro starts at 2.5 mg weekly for 4 weeks, then 5 mg. If needed, the dose goes up in 2.5 mg steps after at least 4 weeks on the current dose, to a maximum of 15 mg. In SURMOUNT-1 (tirzepatide for weight management), mean weight loss at 72 weeks was 15.0% at 5 mg, 19.5% at 10 mg and 20.9% at 15 mg. Follow your prescriber's plan. Source: Mounjaro prescribing information.
Full dosing guide →Can I stay on a lower Mounjaro dose if it is working?
Often, yes, if your prescriber agrees. The labels do not require everyone to reach the top dose. For Zepbound, Lilly notes that 2.5 mg is a starting dose and not an approved maintenance dose. Do not change doses without talking to your prescriber. Source: Lilly Zepbound savings and dosing notes.
Dosing details →Choosing a Provider
What is the best online GLP-1 provider?
It depends on whether you want brand-name or compounded medication, insurance support, and how much clinician contact you need. Compare the full bill (membership plus medication), the cancellation terms and state availability before you pay.
Provider directory →What is the difference between compounded and brand-name GLP-1 providers?
Brand-name providers prescribe FDA-approved medications such as Wegovy, Zepbound, Ozempic and Mounjaro. Compounded products may cost less, but they are not FDA-approved generics and FDA does not review them for safety, effectiveness or quality before marketing. A licensed prescriber should decide whether a compounded drug is medically appropriate and legally available for you. Source: FDA on unapproved GLP-1 drugs.
