GLP-1 Cost Comparison: Brand vs Compounded (2026)
| Compound | Brand Cost | Compounded Cost | Monthly @ Maintenance | Savings |
|---|---|---|---|---|
| Semaglutide | $1,349/mo (Wegovy) | $150-300/mo | $150-300 | 78-89% |
| Tirzepatide | $1,059/mo (Zepbound) | $200-400/mo | $200-400 | 62-81% |
| Retatrutide | N/A (not approved) | $250-500/mo | $250-500 | — |
Brand prices are retail without insurance or manufacturer coupons. Compounded prices vary by pharmacy and dose.
What Affects Your Peptide Therapy Cost?
Dose Escalation Impact
Starting doses (0.25-0.5mg semaglutide) cost 50-70% less than maintenance doses (1-2.4mg). The first 4 months of treatment are significantly cheaper. Budget more as you titrate up.
Vial Size Economics
Larger vials (10mg vs 5mg) typically offer 15-25% lower cost per milligram. However, only buy larger vials if you can use the contents within 28 days of reconstitution.
Pharmacy Variability
Compounding pharmacy prices vary by 30-50% for the same product. Look for 503B pharmacies with cGMP certification. Avoid suspiciously cheap sources—quality testing adds legitimate cost.
Insurance Considerations
Most insurance does not cover compounded peptides. However, some plans cover brand GLP-1s for diabetes (not weight loss). HSA/FSA accounts can typically be used for compounded peptides with a prescription.
Frequently Asked Questions
How much does compounded semaglutide cost per month?
Compounded semaglutide typically costs $150-300 per month at maintenance doses, compared to $1,349/month for brand Wegovy. The exact cost depends on your dose (higher doses cost more), vial size, and compounding pharmacy. Starting doses cost less because you use less medication per week.
What is the price difference between Wegovy and compounded semaglutide?
Wegovy costs approximately $1,349/month at retail price without insurance. Compounded semaglutide costs $150-300/month, representing 78-89% savings. The active ingredient is identical—the price difference reflects brand markup and pharmacy compounding economics, not quality differences.
How much does tirzepatide cost without insurance?
Brand tirzepatide (Mounjaro/Zepbound) costs $1,059/month without insurance. Compounded tirzepatide runs $200-400/month depending on dose and pharmacy. At maintenance doses of 10-15mg weekly, expect the higher end of that range.
How many vials of semaglutide do I need per month?
At a standard 5mg vial reconstituted with 2mL water, you get 20 doses of 0.25mg or 10 doses of 0.5mg. For monthly supply: at 0.25mg weekly you need about 1 vial every 5 weeks; at 1mg weekly you need 1 vial every 5 weeks; at 2.4mg weekly you need roughly 2 vials monthly.
Is compounded semaglutide as effective as brand-name?
Yes, when sourced from a licensed 503B compounding pharmacy using USP-grade semaglutide. The molecule is identical. The FDA permits compounding when brand-name drugs are in shortage. Quality depends on the compounding pharmacy—look for cGMP certification and third-party testing.
What is the cheapest GLP-1 for weight loss?
Compounded semaglutide is currently the most affordable GLP-1 option at $150-300/month. Compounded tirzepatide costs slightly more ($200-400/month) but may produce faster results for some users. Generic semaglutide is not yet available in the US as patents extend through 2031.
How do I budget for peptide therapy long-term?
Plan for 12-18 months of treatment minimum. Costs are lower during dose escalation (months 1-4) and higher at maintenance. Budget $150-250/month for semaglutide or $200-350/month for tirzepatide. Add $20-50/month for supplies (syringes, alcohol swabs, sharps container). Many users maintain results on lower doses long-term.
Are compounded peptides legal?
Yes, compounded medications are legal in the US when prescribed by a licensed provider and prepared by a licensed compounding pharmacy. The FDA Drug Shortage List currently includes semaglutide, permitting 503B pharmacies to compound it. This status can change—check current shortage listings.
