Zealthy Tirzepatide Review: Cost, a Confirmed FDA Warning Letter & Honest Verdict (2026)

This review's most important finding, confirmed directly against FDA's own warning-letter database: Zealthy's legal entity, FitRX, LLC dba Zealthy, received a genuine FDA warning letter, issue-dated September 9, 2025, for "Unlawful Sale of Unapproved and Misbranded Drugs to United States Consumers Over the Internet (Telehealth)." Every fact here comes from the company's own published program plus this review's own direct verification.

A confirmed FDA warning letter, plus active legal and regulatory action

This review queried FDA's public warning-letter database directly and confirmed a genuine entry: "FitRX, LLC dba Zealthy," issued by CDER, issue date 09/09/2025, posted 09/16/2025, subject "Unlawful Sale of Unapproved and Misbranded Drugs to United States Consumers Over the Internet (Telehealth)." This matches, and confirms, the ranking's underlying claim. On top of the confirmed warning letter, Zealthy also faces an active Novo Nordisk false-advertising lawsuit alleging trademark infringement and marketing compounded drugs as FDA-approved alternatives, and active DOJ/FTC enforcement alleging undisclosed subscription terms, locked cancellation, and unauthorized health-data sharing. Zealthy's founder, previously ran Cerebral, which settled with the FTC in 2024 over similar deceptive practices, and the company recently rebranded to Gronk Inc. amid this active enforcement.

What Zealthy is

Zealthy (legal entity FitRX, LLC, recently renamed to Gronk Inc.) offers compounded semaglutide and tirzepatide, via an asynchronous telehealth model — no video visit required, which removes friction for patients who don't want one. It serves 34 states, with independent licensed prescribers retaining full clinical authority.

What Zealthy costs

$351/month at the starting dose, plus a separate fee, with pricing not published until after the intake.

The brand-vs-compounded question

Zealthy dispenses compounded semaglutide and tirzepatide — which the pending Novo Nordisk lawsuit alleges were marketed as FDA-approved alternatives. Compounded tirzepatide is pharmacy-made, not itself an FDA-approved finished drug, and was not the specific product studied in the pivotal trials. See our guide to whether compounded tirzepatide is still legal in 2026 for the regulatory picture.

How the care model holds up

Zealthy's asynchronous model and broad 34-state footprint are real conveniences for patients who want to avoid a video visit. But the trade-offs here are the most serious here, and this review independently confirmed the central one: a genuine FDA warning letter, issued September 2025, for unlawful sale of unapproved and misbranded drugs. Layered on top: active DOJ/FTC enforcement over undisclosed subscription terms and locked cancellation, an active Novo Nordisk trademark lawsuit, and a founder with a prior FTC settlement at a previous company. Given a confirmed active FDA warning letter and multiple active enforcement actions, this review recommends most readers look elsewhere until these matters are resolved; tirzepatide carries labeled warnings for acute pancreatitis, gallbladder disease, and a boxed thyroid C-cell tumor warning — see our guides on Zepbound side effects, the gallbladder risk, and the thyroid cancer warning.

Does the drug work? (Separate from the provider)

Judge the provider on price, oversight and disclosure; judge the molecule on its trials. Tirzepatide's are strong — roughly 15–21% of body weight over 72 weeks in SURMOUNT-1¹, and better than semaglutide head-to-head² — but they were run on the brand drug at FDA-approved doses. Our tirzepatide evidence guide has the full picture.

The honest verdict

This review independently confirmed a genuine FDA warning letter against Zealthy's legal entity, layered on top of active DOJ/FTC enforcement and a pending trademark lawsuit — the most serious regulatory picture in this entire ranking. Until these matters resolve, compare it instead against a provider with a clean, confirmed record, like Vitara RX or Zera Health. See our best tirzepatide providers ranking for the full field.
