Provider review

RxSpan MD review: it names its doctor, and never says what a price buys

RxSpan MD does something most of this market avoids: it names the doctor behind the service, with a full biography and a credential you can check. Then it publishes a price list with no billing period on it. Semaglutide is $249 — for what? A month, a quarter, one vial? The page does not say, there are no product pages to click through to, and no wording anywhere near those figures gives a term. You would have to start the signup to find out what you are being asked to pay for.

Names its physician and his credentials, then lists every price with no billing period attached to any of them.

Worth trusting if

  • You want the doctor behind the service named, with a biography you can check
  • You want a seller that makes no promise about how much weight you will lose
  • You want the branded products listed beside the compounded ones at their real prices

Be skeptical if

  • You need to know whether a price is a month, a quarter or a single vial before you start
  • You want to know which pharmacy fills the prescription
  • You want a physician whose board specialty is metabolic or internal medicine

Provenance

What RxSpan MD actually dispenses

Regulatory category is the axis consumers are most reliably misled about, so it comes first. Every product below is sorted by what it legally is, not by what it costs.

FDA-approved1 product

The finished product holds an FDA approval and carries an NDC. Approval covers the specific product, dose form and indication on the label — not the molecule in general.

  • Wegovy, brandListed at $1,349 against $249 for the compounded version.
Compounded (503A)2 products

Prepared by a state-licensed pharmacy against a prescription for a named patient. Compounded preparations are not FDA-approved and are not reviewed by FDA for safety, effectiveness or quality.

  • Compounded semaglutide injectionListed at $249 with no billing period stated anywhere on the page.
  • Compounded tirzepatide injectionListed at $329 for the injection and $349 for capsules, both without a term.

Evidence

Has the molecule been tested for what it is sold for?

One row per product, graded on how far the published human evidence goes for the MOLECULE inside it, for the use it is sold for — not for the molecule in general, and never a claim about this seller. Nobody trials a compounded preparation; what a trial can tell you is whether the molecule has been tested for the thing it is being advertised to do. A molecule with phase 3 evidence for one outcome has none for another, and that distinction is where peptide marketing lives.

Phase 3 trials

What the trials show for Semaglutide

  • NCT03548935 STEP 1Phase 3, completed, n=1,961. 68 weeks in 1,961 adults, titrated to semaglutide 2.4 mg, mean weight reduction of about 15%. Listed as the molecule's evidence base; RxSpan MD cites no trial anywhere on its site.

There is no outcome claim here to weigh against the trial. RxSpan MD sells on the credential of its physician and on convenience, and attaches no weight-loss percentage, pounds figure or timeline to this product anywhere. What is missing instead is the commercial information a buyer needs: the figure beside the product has no billing period attached, no product page exists to explain it, and the only qualifier in sight is a site-wide coupon. Saying nothing about efficacy is the right instinct; saying nothing about what that figure buys is not the same kind of restraint.1

Phase 3 trials

What the trials show for Tirzepatide

  • NCT04184622 SURMOUNT-1Phase 3, completed, n=2,539. 72 weeks in 2,539 adults at 5, 10 and 15 mg once weekly, mean reduction of roughly 21% at the top dose. Again the molecule's evidence base rather than a citation this seller makes.

The same pattern: a product name, a bare figure and no promise. Worth noting that RxSpan MD prices tirzepatide capsules above the injection, which is the usual direction in this market because an oral formulation generally needs far more drug to reach a comparable exposure — but no trial cited anywhere on this site, or on any site we grade, tested a compounded tirzepatide capsule. Nothing here overstates the evidence, and nothing here connects the product to it either.2

Phase 3 trials

What the trials show for Semaglutide

  • NCT03548935 STEP 1Phase 3, completed, n=1,961. The trial supporting approval of this exact product. Unlike the compounded rows, the evidence here attaches to the thing being sold.

The branded products are the one place on this site where the trial evidence attaches directly to what is being sold, and RxSpan MD claims nothing for them beyond listing them. The gap between $1,349 for branded semaglutide and $249 for the compounded version is the trade a buyer is actually being offered, and the site does not frame it either way. Ozempic sits in the same list at $1,299, which is a diabetes medicine rather than a weight-management one — worth knowing before comparing the two figures.1

Dispensing chain

Who actually fills your prescription

Pharmacy not named
Read the full account

No pharmacy is named. The terms say only that medications may be fulfilled by licensed pharmacies if prescribed, and nothing states whether your medication would be made to order under your prescription or dispensed ready-made. What RxSpan MD does name, unusually, is its physician — Dr. John Diaz, with a biography covering his degree, his medical school and his honors. That credential is real and checkable, and it is worth reading precisely: the board certification named is in plastic surgery rather than in endocrinology or internal medicine. That is not a disqualification, and plenty of physicians practice weight management outside their board specialty. It is simply the fact, and a site that leads with a doctor's credentials invites a reader to look at them.

Third-party testing, and what is published

Nothing published on the pages searched

Certificate of analysis readable

No lot report a buyer can open

Read the full testing account

No certificate of analysis, potency, purity or sterility result is published — and neither is a billing period or a product page. The price list is a single index of bare figures, and every product address we tried returned a page that does not exist. The only strong claim on the whole property sits on a line this page does not grade: the hair-loss category promises clinically proven topicals and orals to slow loss and support regrowth, with no study named. Its weight-loss and peptide lines make no efficacy claim at all, which is the right instinct and leaves nothing to verify in either direction.

Licensing

Licensed to dispense, and where

Coverage

RxSpan MD publishes no list of states and makes no nationwide claim, checked on September 13, 2026 across the homepage, the products page, the about page and the terms. Its terms require that you be in the same state as your shipping address at the time of a consultation, which describes how telehealth works rather than where this company operates.

Read the full licensing claim

The operating company is named in its terms as RxSpan MD LLC, and a named physician is presented with a full biography on the about page. No pharmacy is named, and no address or state of incorporation appears.

Regulatory

The FDA warning letter

Checked, and none found

A search of the 113 warning letters issued to telehealth firms in the September 9, 2025, February 20, 2026 and June 8, 2026 enforcement waves — matched on full company name rather than substring, because a substring match attaches one company’s regulatory history to another — returns no entry for RxSpan MD (RxSpan MD LLC). That is a statement about those three waves as of September 2026, not a claim that no action exists anywhere.

Assessment

What holds up, and what does not

What holds up
  • It names its physician and publishes his degree, medical school and honors.
  • It names its operating company in its own terms.
  • It makes no weight-loss claim of any kind on its GLP-1 or peptide products.
Show 3 more
  • It lists the branded products beside the compounded ones, so the price gap is visible.
  • It publishes prices at all, before any signup, which several sellers we grade do not.
  • No FDA warning letter, against the brand or the named physician.
What does not
  • Not one price on the site carries a billing period — no month, supply, term or per-anything.
  • There are no product pages; every product URL we tried returned a not-found page.
  • The physician it names is board-certified in plastic surgery rather than metabolic medicine.
Show 4 more
  • No pharmacy is named, and nothing says whether the medication is made to order.
  • A 10% site-wide coupon means the first charge differs from every figure listed.
  • Its hair-loss line claims clinically proven treatments and names no study.
  • It sells NAD+, sermorelin and glutathione with no product page, dose or trial reference.

Verdict

The bottom line

Before anything else, ask what $249 buys — a month, a quarter, or one vial. Nothing on this site answers that, and it is the first thing you need. The physician is named and his credentials are real, which is more than most of this market offers; just read them carefully, because the board that certified him certified him in plastic surgery.

It names the doctor

From RxSpan MD's about page:

"Meet Dr. John Diaz. Dr. John Diaz is a board-certified plastic surgeon with more than 20 years of experience… He earned his undergraduate degree from Cornell University… went on to attend the Albert Einstein College of Medicine… He received his M.D. with Distinction in Research and was honored with Alpha Omega Alpha recognition, awarded to the top 10% of medical students nationwide."

That is a real, named, checkable physician with real credentials, and most sellers we grade name nobody at all.

Read the specialty carefully, though. The board named is plastic surgery — not endocrinology, not internal medicine. That is not a disqualification: physicians prescribe lawfully outside their board specialty and many practice weight management. But a site that leads with a doctor's credentials as the reason to trust it is inviting you to look at them, so look.

And then the price list

Here is RxSpan MD's entire price list, as published:

Semaglutide Injection $249 · Semaglutide Capsules $249

Tirzepatide Injection $329 · Tirzepatide Capsules $349

Wegovy® $1,349 · Zepbound® $1069 · Ozempic® $1299

$249 for what?

A month? A three-month supply? A single vial? We swept that page on 13 September 2026 for the words month, supply, per, starting and from anywhere near a figure. None of them appears.

There are no product pages to click into either — we tried three URL patterns and every one returned a not-found page. So that list is the whole of it: seven numbers with nothing attached.

A 10% coupon rides every page as well, so the first charge is below all seven, and nothing says whether it repeats.

What it does not claim

On the GLP-1 and peptide side, nothing at all. No weight-loss percentage, no pounds figure, no timeline, no testimonial. Nothing here reaches past STEP 1 1 or SURMOUNT-1 2 because nothing here reaches.

The one strong claim on the property is in a different aisle:

"Clinically proven topicals and orals to slow loss and support regrowth."

That is the hair-loss line, which this page does not grade — noted so our silence is not read as agreement.

The products it sells and will not describe

The affiliate program behind this site pays separate rates for NAD+, sermorelin and glutathione. All three appear in the price list. None has a product page, a dose, or a trial reference anywhere on the site.

We have not graded them, because grading a claim about a drug the seller has not described means inventing both halves.

Questions

Frequently asked questions

What does $249 actually buy?

RxSpan MD doesn't say. That figure sits on its products index with no billing period attached, there are no product pages to click through to, and nothing near it says month, supply or term. You would have to begin the signup to find out.

Who is the doctor?

Dr. John Diaz, named on the about page with his degree, medical school and honors. He is board-certified in plastic surgery rather than endocrinology or internal medicine, which is worth knowing on a site that presents the credential as the reason to trust it.

Does it claim how much weight I'd lose?

No — no percentage, pounds figure or timeline appears on any GLP-1 or peptide product. That means nothing here overstates the trials, and it also means the site gives you nothing to set expectations against.

Why is Wegovy five times the price?

Because it is the manufacturer's approved product rather than a compounded preparation made to order by a pharmacy. The trial evidence attaches directly to Wegovy; for the compounded version it describes the molecule rather than the preparation you would receive.

What about the NAD+ and sermorelin products?

They appear in the price list and nowhere else — no product page, no dose, no trial reference. We have not graded them, because there is nothing published to grade against.

Glossary

Key terms

Show definitions
Board certification
A specialty credential awarded after additional training and examination in one field of medicine. A physician may lawfully prescribe outside their board specialty; the certification tells you where their formal training was concentrated.
Compounded
Made to order by a pharmacy for an individual patient rather than manufactured and approved as a finished product. Compounded drugs are not FDA-approved and the FDA has not evaluated their safety, effectiveness or quality.
STEP 1
The phase 3 trial of once-weekly semaglutide 2.4 mg for weight loss — 1,961 adults over 68 weeks, published in the New England Journal of Medicine in 2021.

Method

How we checked this

Non-product facts last checked September 2026. Read the editorial policy for the rules this page is held to.

Read our methodology

Claims read first-party

Every quoted claim was read off RxSpan MD's own pages, first-hand, on the date stamped against it — never from a summary, an aggregator, or an earlier version of this review.

Trials read from the registry

Phase, status and enrollment come from ClinicalTrials.gov; identifiers and journals from PubMed's own records. Nothing here is cited from memory.

Absence claims bounded

Where we report that no trial exists, the page says what was searched, where, and when — never an unbounded claim that nobody has tested something.

Letters matched on full name

FDA letters are matched on the complete company name. A substring match would attach one firm's regulatory history to another with a similar name.
