Buy Tirzepatide Online: Verified Providers Ranked

Two verified telehealth platforms let you buy tirzepatide online with a prescription: BiltRx at $129 per month and Arc-1 from $199.99. Both use licensed US 503A compounding pharmacies and require a medical consultation before dispensing. We evaluated each on pricing, pharmacy credentials, consultation process and shipping. Below is what we found.

Verified Providers Selling Tirzepatide Online

We reviewed dozens of online tirzepatide sellers. Most failed basic verification: no pharmacy license on file, no prescription requirement, or products labeled "research use only." Two passed every check. BiltRx and Arc-1 are both LegitScript certified, use US-licensed 503A pharmacies, and require a provider consultation before dispensing compounded tirzepatide.

How We Evaluate Each Provider

Our review checks four criteria: LegitScript certification status, state pharmacy licensing, whether a medical consultation is mandatory, and whether pricing is published transparently. A provider that fails any one of these does not appear on this site. We re-verify these credentials quarterly.

BiltRx: Compounded Tirzepatide at $129 per Month

BiltRx offers compounded tirzepatide at a flat $129 per month regardless of dose. The platform also provides access to brand-name Mounjaro ($1,499/mo) and Zepbound ($1,499/mo) for patients who prefer FDA-approved formulations or whose insurance covers them. Consultation and shipping fees apply separately; BiltRx does not publish exact amounts for either on its website.

The consultation is conducted by licensed US providers who review your medical history, screen for contraindications and set your starting dose. BiltRx does not publish specific dose tiers publicly. Your provider determines the concentration and adjusts it over time. For a full breakdown, see our BiltRx review.

Arc-1: Dose-Tiered Tirzepatide with Glycine and B12

Arc-1 compounds tirzepatide at 10 mg/mL with glycine (5 mg/mL) and vitamin B12 (500 mcg/mL). Pricing varies by prescribed dose: $199.99 for 2.5 mg, $249.99 for 5 mg, $399.99 for 7.5 mg. Consultation and expedited shipping are both free. The platform offers a 30-day satisfaction guarantee on eligible purchases.

Arc-1 does not ship to five states: California, Arkansas, Indiana, Minnesota and South Carolina. If you live in one of these states, BiltRx or a brand-name prescription through your local pharmacy are the available alternatives. Read our Arc-1 review for the full product breakdown.

Side-by-Side Provider Comparison

What You Need to Buy Tirzepatide Online

Buying tirzepatide online is not like ordering a supplement. Three requirements must be met before any legitimate provider will ship medication to you.

A Valid Prescription from a Licensed Provider

Both platforms require completion of a health intake form followed by provider review. The provider evaluates your BMI, medical history and current medications. If clinically appropriate, they write the prescription. If not, they explain why and may suggest alternatives. You cannot skip this step.

State Availability Check

Telehealth prescribing and pharmacy shipping regulations vary by state. Arc-1 explicitly does not serve California, Arkansas, Indiana, Minnesota or South Carolina. BiltRx says availability varies but does not list specific exclusions. Confirm your state is covered before starting the consultation.

Payment and Insurance Options

Compounded tirzepatide is typically not covered by insurance because it is not FDA-approved. Both providers accept standard payment methods. BiltRx mentions that insurance coverage varies by plan but does not guarantee coverage. HSA and FSA eligibility depends on your specific plan; neither provider makes a definitive statement about acceptance. Brand-name Zepbound and Mounjaro through BiltRx may be covered by some commercial insurance plans with prior authorization.
