Vyvron review: 13 charges a year, not 12

Vyvron (vyvron.com) is new. Its testimonial section still says patient stories are coming once founding members give written consent, which is an honest thing to ship and also an unambiguous statement that this desk has no track record yet. We read its pricing out of its own application bundle in August 2026, because the site is a single-page app that serves an identical shell for every route and renders nothing a text fetch can see. Two findings came out of it, and both change what the advertised numbers mean.

Finding one: a month is not a month

Vyvron's fine print reads "$199 per 4 weeks, billed every 4 weeks; auto-renews until you cancel." Elsewhere on the same site, the same plan is advertised as "from $199/mo" and "starting at $199/mo".¹

Four weeks is not a month. Billing every 28 days produces 13 charges in a calendar year, not 12. At the $199 rung that is $2,587 a year, not the $2,388 a reader doing the obvious arithmetic would budget. The extra charge is not hidden — the cadence is disclosed in the fine print — but the unit on the headline is wrong, and a wrong unit on a recurring charge compounds quietly. This is a variant of the pricing behavior we catalog in why GLP-1 prices move: the number is accurate and the label is not.

Finding two: you cannot buy tirzepatide monthly

Vyvron's weight-loss page shows three tiers. Start is $199 per four weeks, recurring, and it is semaglutide only — the only recurring rung anywhere on the site. Transform, badged most popular, displays "$285/mo" and is in fact $790 billed once for twelve weeks of tirzepatide. Premium displays "$248/mo" and is $2,981 billed once for a full year of tirzepatide.¹

So there is no month-to-month tirzepatide plan at Vyvron. The smallest tirzepatide purchase is $790 up front. We do not file a monthly tirzepatide figure for this desk, because none exists, and any ranking that prints "Vyvron tirzepatide, $285/mo" is printing a price that cannot be bought for one month. If tirzepatide is the molecule you are shopping, our tirzepatide cost guide and the tirzepatide wire are the places to compare desks that actually sell it by the month.

There is a smaller arithmetic problem inside that same table. The "$285/mo" comes from dividing $790 across twelve weeks read as roughly 2.77 calendar months. Divide it instead by three four-week cycles — the unit Vyvron itself bills in — and it is $263 a cycle. Two different definitions of "per month" are in use inside one pricing table.

The founding-rate layer

Vyvron currently sells at founding rates: $199 per four weeks for weight loss, $149 for microdosing, $189 for longevity, against list rates of $249, $179 and $229 respectively once founding pricing closes. Its longevity products price individually at $229 a month for injectable NAD+, $229 for injectable sermorelin and $145 for B12-MIC.

The homepage disagrees with all of that. Its program cards say weight loss starts at $199, microdosing at $179 and longevity at $145. We take the program pages as authoritative, because that is where the enrollment button and the billing disclosure sit — and note what the two homepage figures actually are. The $145 is the cheapest single longevity product rather than the longevity program price. The $179 is the post-founding microdosing list price, displayed as though it were what you would pay today. Neither is fabricated. Both are the wrong number in the place they appear.

One more piece of the same furniture: the banner reading "100 of 100 founding spots left" is a hardcoded constant with a progress bar fixed at full width. It is not a live counter and it will not move.

What Vyvron discloses better than anyone here

Credit where it is earned. Vyvron publishes the most specific state disclosure in this batch: all 50 states plus the District of Columbia, with a live video visit required in Arkansas, DC, Delaware, Kansas, Mississippi, New Mexico, Rhode Island and West Virginia, and compounded GLP-1 unavailable in Mississippi where only branded product is offered. That is the level of detail our state-by-state telehealth guide says a desk should publish, and almost none of them do — Auren Rx publishes no state list at all.

Its clinical layer is OpenLoop Health and OpenLoop Healthcare Partners, named in the privacy policy. OpenLoop is a real, substantial telehealth infrastructure company, and it is the strongest thing on this site.

What it does not disclose

No pharmacy is named — the site says only "a licensed pharmacy". No prescriber is named and no NPI is published. The corporate entity is Vyvron, LLC at a Sheridan, Wyoming address that is among the most heavily used registered-agent mail drops in the country, so it tells you nothing about where anything happens. Its LegitScript seal does resolve to a real certification record.

Fees, refunds and the exit

You are charged when you complete the intake, before a provider reviews it. A full refund is available only if you cancel within 72 hours with no services rendered, or if a provider medically disqualifies you. Canceling a recurring plan requires 72 hours' notice before the next billing date or you are charged for that cycle; there are no cancellation fees. On the prepaid Transform and Premium plans, only months whose medication has not shipped are refundable — which is worth reading twice before handing over $790 or $2,981.

The regulatory screen

The trading name and the clinical partner both returned zero company-column matches in the FDA's live warning-letter index in August 2026, against a positive control that correctly returned a known February 2026 letter for an unrelated telehealth seller.² Nothing in the enforcement record counts against this desk.

Where it lands

If you want semaglutide and you read the cadence correctly, $199 every four weeks is a fair recurring rate and OpenLoop behind it is a genuine reassurance. Everything else here asks you to pay a lot up front to a company with no patient history, no named pharmacy and no named prescriber, on a page where two surfaces disagree about the price and the scarcity counter is decorative. Run it against the five-minute provider checklist before you decide, and if you want a desk with an explicit monthly rung on both molecules, Auren Rx and Trellis Vitality both have one.
