Verified Tirzepatide Providers: Licensed and Certified

We checked 40+ online tirzepatide sellers in 2026 and verified two that meet all four of our criteria: LegitScript certification, US pharmacy licensing, mandatory medical consultation and published pricing. BiltRx and Arc-1 are the only providers listed on this site. This page explains what "verified" means, profiles each provider, and explains why we exclude the rest.

What Makes a Tirzepatide Provider Verified

We use the word "verified" to mean we personally checked four criteria against public records and the provider's own disclosures. Passing all four is the minimum to appear on this site.

LegitScript Certification Explained

LegitScript is an independent service that reviews telehealth platforms, pharmacies and supplement sellers for regulatory compliance. Certification means the provider has been evaluated for proper licensing, legitimate prescribing practices and lawful pharmacy partnerships. Google and Meta require LegitScript certification before approving ads for prescription medications and telehealth services. Both BiltRx and Arc-1 are LegitScript certified.

State Pharmacy Licensing

Every 503A compounding pharmacy must hold a license from the state board of pharmacy in each state where it dispenses medications. We verified that the compounding pharmacies used by both providers hold active state licenses. You can independently verify any pharmacy on your state board of pharmacy's public license database.

Prescription and Consultation Requirements

Both providers require completion of a health intake form and evaluation by a licensed medical provider before prescribing tirzepatide. Neither allows direct purchase without a consultation. This is non-negotiable for any provider we would list.

• LegitScript certified - verified on legitscript.com
• 503A pharmacy licensed - verified against state board records
• Medical consultation required - tested by walking through the signup process
• Pricing published - medication cost listed on the provider's product page

BiltRx Provider Profile

Certification and Licensing

BiltRx holds LegitScript certification for its telehealth platform. The compounding pharmacy partner is US-licensed under 503A. BiltRx is based in Houston, Texas, and operates as a HIPAA-compliant telehealth service. The platform is not a pharmacy itself; it connects patients with licensed providers and partner pharmacies.

Pricing and What Is Included

Compounded tirzepatide: $129 per month, all doses. Consultation and shipping fees apply separately. BiltRx does not publish exact amounts for either. Brand-name Mounjaro and Zepbound are also available at $1,499 per month. The $129 compounded price is the lowest published medication cost we found among verified providers. For the full review, see our BiltRx page.

Consultation and Prescribing Process

After signing up, patients complete a health intake form. A licensed US provider reviews the submission, evaluates clinical appropriateness, screens for contraindications and prescribes if approved. The provider sets the starting dose and adjusts it over time. BiltRx also offers weight-loss coaching support and refill coordination.

Arc-1 Provider Profile

Certification and Licensing

Arc-1 holds LegitScript certification. The compounding pharmacy is US-licensed under 503A. Board-certified physicians in Arc-1's provider network handle the medical review and prescribing. The platform is HIPAA compliant.

Pricing by Dose Tier

Arc-1 publishes transparent dose-tiered pricing on its product page: $199.99 (2.5 mg), $249.99 (5 mg), $399.99 (7.5 mg). Consultation and expedited shipping are included in these prices. Higher doses (10 mg, 12.5 mg, 15 mg) are not listed as product options. Full details are in our Arc-1 review.

Formulation and Extras

Arc-1's tirzepatide formulation includes glycine (5 mg/mL, for cellular repair support) and vitamin B12 (500 mcg/mL, for energy and red blood cell production). This is a differentiator from BiltRx, which compounds tirzepatide alone. Both are injectable formulations administered as weekly subcutaneous injections.

State Restrictions

Arc-1 does not ship to California, Arkansas, Indiana, Minnesota or South Carolina. This is due to the combination of state telehealth prescribing rules and pharmacy shipping regulations in those jurisdictions. Patients in these five states should check BiltRx availability or pursue a brand-name prescription through a local provider.

Provider Comparison

Providers We Do Not List and Why

Most tirzepatide sellers we reviewed failed at least one of our four criteria. The most common failures fall into three categories.

No Prescription Required

Several websites sell tirzepatide as a direct-purchase product. No health intake, no provider review, no prescription. This violates federal law. Tirzepatide is a prescription medication with a boxed warning and contraindications. Sellers who skip the prescription step are a danger to buyers.

Research Chemical Sellers

Some vendors market tirzepatide as a "research peptide" or "for research use only." These products are manufactured for laboratory use, not human injection. They lack the sterility testing, potency verification and pharmacy oversight that compounded prescription medications require. We do not name or link to these sellers because doing so could imply legitimacy.

Unverified Compounding Sources

A third category includes platforms that claim to compound tirzepatide but cannot provide verifiable LegitScript certification or pharmacy license numbers. Some of these may be legitimate but have not sought certification. Without verification, we cannot list them.
