Pros & Cons
Wisp
Pros
- ✓Wider GLP-1 menu than the prior stub suggested — both branded injectables (Wegovy, Zepbound, Saxenda) AND the compounded sublingual option
- ✓LegitScript certified, board-certified providers (Dr. Shannon Chatham DO, Andrea Sleeth WHNP-BC publicly named)
- ✓Wisp's product page uses appropriately cautious language around sublingual: 'lab tests using human-derived tissues suggest it may begin working' and 'effectiveness in patients may vary' — disclosure is more rigorous than most compounded GLP-1 marketing
Cons
- ✗EFFECTIVENESS CAVEAT: sublingual compounded semaglutide has not been tested in humans — Wisp's own product page explicitly states this. Injectables (Wegovy, Zepbound, Saxenda) on the same platform have FDA safety/efficacy data; sublingual does not.
- ✗Pharmacy partners not publicly named
- ✗States served list not publicly enumerated
Zealthy
Pros
- ✓34 states served — meaningful nationwide footprint
- ✓Asynchronous model removes friction for patients comfortable without a synchronous video visit
- ✓Independent licensed prescribers retain full clinical authority
Cons
- ✗TWO FDA warning letters for false/misleading marketing of compounded GLP-1s (Feb 2026 letter 717987 verified at fda.gov; September 2025 letter from secondary sources)
- ✗Active Novo Nordisk false-advertising lawsuit: Novo Nordisk A/S et al v. Zealthy Inc., case 1:25-cv-06391 (S.D.N.Y., filed 2025-08-04), alleging trademark infringement and marketing of compounded products as 'FDA-approved alternatives'
- ✗Active DOJ/FTC enforcement: United States v. Cerebral, Inc. et al, case 1:24-cv-21376 (S.D. Fla., amended complaint adding Zealthy Inc., Gronk Inc., founder Kyle Robertson, and others), alleging ROSCA violations (failure to disclose subscription terms, no informed consent for billing, locked cancellation), and unauthorized health-data sharing for targeted advertising
- ✗Founder pattern of conduct: Kyle Robertson previously founded Cerebral, which settled with the FTC in June 2024 ($5M consumer redress + $10M civil penalty suspended to $2M) for similar deceptive practices. Robertson then founded Zealthy and is alleged to have continued the same conduct
- ✗Company recently renamed FitRX/Zealthy to Gronk Inc. — rebrand pattern is itself a concerning signal in the context of active enforcement
- ✗Continued marketing of compounded semaglutide after FDA removed it from the shortage list on 2025-02-21 (post-shortage compounding without legal authorization)
- ✗Adds a $135/month membership fee on top of medication cost — total cash price is $286-$351/month
- ✗Compounded only — no FDA-approved Ozempic, Wegovy, Zepbound, or Mounjaro option
Our Verdict
Wisp edges out Zealthy with a higher overall score of 7.0/10 and is particularly strong for buyers who want a board-certified telehealth platform offering both branded injectables AND a sublingual alternative — with full disclosure that the sublingual form is not human-tested. Zealthy remains a solid alternative, especially if you're looking for not currently recommended — listed for transparency and reader awareness only.
