Brand-Name Tirzepatide Cost
Eli Lilly manufactures both brand-name tirzepatide products. The pricing is identical at list level, but insurance coverage differs by indication.
Zepbound (Eli Lilly) Retail Price
Zepbound is FDA-approved for chronic weight management in adults with BMI 30+ or 27+ with a weight-related comorbidity. The list price is $1,499 per month, or $17,988 per year. Zepbound comes in pre-filled auto-injector pens at fixed doses: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg. The dose escalation schedule is set by the prescribing provider.
Mounjaro (Eli Lilly) Retail Price
Mounjaro is FDA-approved for type 2 diabetes. Same active ingredient, same manufacturer, same $1,499 monthly list price. The key difference is the FDA indication. Insurance plans that cover GLP-1 medications for diabetes may cover Mounjaro more readily than Zepbound, which is indicated for weight management.
Insurance Coverage and Prior Authorization
Commercial insurance plans vary widely. Some cover Mounjaro for diabetes with a copay as low as $25 after prior authorization. Fewer plans cover Zepbound for weight loss without diabetes. Prior authorization requires your doctor to submit documentation of medical necessity. The insurer reviews and either approves, denies, or requests additional information. This process can take days to weeks.
Manufacturer Savings Programs
Eli Lilly offers savings cards for both Zepbound and Mounjaro. For commercially insured patients, these can reduce copays to as low as $25 per month. Patients on Medicare, Medicaid or other government programs do not qualify. Terms and availability change; check the manufacturer website for current offers. These savings do not apply to compounded tirzepatide.
Compounded Tirzepatide Cost
Compounded tirzepatide is significantly cheaper than brand-name because it is not manufactured by Eli Lilly and is not FDA-approved. The trade-off is a different regulatory status and pharmacy source.
BiltRx at $129 per Month
BiltRx advertises $129 per month for compounded tirzepatide at any dose. This is the published medication price. Consultation and shipping fees apply separately but are not listed on the product page. BiltRx uses US-licensed 503A compounding pharmacies. The annual medication cost alone is $1,548. With estimated consultation and shipping, the total is higher, but we cannot calculate it precisely because those fees are not published.
Arc-1 from $199.99 per Month
Arc-1 prices by dose tier: $199.99 (2.5 mg), $249.99 (5 mg), $399.99 (7.5 mg). These prices include consultation and expedited shipping. The formulation adds glycine and B12. The annual cost at the lowest tier is $2,399.88; at the highest, $4,799.88. Arc-1 does not serve CA, AR, IN, MN or SC.
| Provider | 2.5 mg/mo | 5 mg/mo | 7.5 mg/mo | 12-Month Total (lowest dose) |
|---|---|---|---|---|
| BiltRx | $129 | $129 | $129 | $1,548 + extras |
| Arc-1 | $199.99 | $249.99 | $399.99 | $2,399.88 |
Annual Cost Comparison
Over 12 months, the gap between brand-name and compounded tirzepatide is substantial even before accounting for dose escalation.
BiltRx medication-only annual cost is 91% less than brand-name list price. Arc-1 at 2.5 mg is 87% less. At higher Arc-1 doses, the savings percentage decreases but remains significant. Use our cost calculator to model your specific scenario with dose escalation over time.
Insurance and Tirzepatide
Insurance adds complexity. Whether tirzepatide is affordable depends heavily on your plan, the indication, and your willingness to navigate prior authorization.
Which Plans Cover Zepbound or Mounjaro
Commercial plans from major carriers (UnitedHealthcare, Aetna, Cigna, Blue Cross Blue Shield) vary by employer and plan tier. Some cover Mounjaro for type 2 diabetes as a preferred brand. Fewer cover Zepbound for weight management. Plans that do cover weight-loss medications often require step therapy (trying a cheaper medication first) or prior authorization.
Prior Authorization Process
Your doctor submits a prior authorization request documenting your BMI, weight-related comorbidities and previous weight-loss attempts. The insurer reviews against their coverage criteria. Approval can take 3-14 business days. Denial rates for weight-loss indications are higher than for diabetes indications. If denied, you can appeal.
Appeals and Exceptions
An initial denial is not the final answer. Your doctor can file an appeal with additional clinical documentation. Some patients succeed on appeal by providing evidence of failed prior treatments, worsening comorbidities, or specialist recommendations. The appeals process varies by insurer but typically allows two levels of internal review before an external review.

FAQ - Tirzepatide Cost
How much does tirzepatide cost per month without insurance?
Brand-name Zepbound and Mounjaro list at $1,499 per month. Compounded tirzepatide from BiltRx is $129 per month (plus consultation and shipping). Arc-1 ranges from $199.99 to $399.99 per month depending on dose, with consultation and shipping included.
Is compounded tirzepatide cheaper than Zepbound?
Yes, by a large margin. BiltRx at $129 per month is 91% less than Zepbound's $1,499 list price. Arc-1 at $199.99 (lowest dose) is 87% less. Compounded tirzepatide is not FDA-approved, which is a significant regulatory difference.
Can I use HSA or FSA to pay for tirzepatide?
HSA and FSA eligibility depends on your specific plan and whether the expense qualifies as a medical expense under your plan's terms. Neither BiltRx nor Arc-1 makes a definitive statement about HSA/FSA acceptance. Consult your plan administrator.
Will tirzepatide get cheaper when a generic is available?
Eli Lilly's patent protection on tirzepatide extends for several years. A generic version is not expected in the near term. When patents expire and generic competition enters the market, prices typically drop, but that timeline is uncertain.
Does Medicare cover tirzepatide for weight loss?
Medicare Part D generally does not cover medications prescribed solely for weight loss. Mounjaro for type 2 diabetes may be covered under Part D depending on the specific plan formulary. The Inflation Reduction Act provisions affect Medicare drug pricing, but weight-loss-only coverage remains limited. Check with your Part D plan.
