RxSpan MD Review 2026
Reviewed August 7, 2026 · Both — compounded GLP-1, brand-name GLP-1 and microdosing options, plus compounded NAD+, sermorelin and glutathione. Compounded products are not FDA-approved.
Visit RxSpan MD WebsiteOverview
RxSpan MD is a physician-founded telehealth practice covering weight loss, longevity, hair loss and sexual health, built around the idea of extending healthspan through prescribed medication. Its most distinctive feature is one almost no competitor in this directory offers: it names the doctor behind it. Dr John Diaz is identified as a board-certified plastic surgeon with more than 20 years of experience, and the site explains his route into the practice — patients seeking aesthetic treatment who also asked for guidance on weight, nutrition and general wellness. Publishing a named, checkable clinician with a stated specialty and background is more accountability than the anonymous 'licensed providers' formulation used almost everywhere else here, and it deserves credit. The weight-loss offering is also sensibly structured, spanning compounded GLP-1, brand-name GLP-1 and a microdosing option, so a patient is not locked into whichever route the platform happens to stock. On the sexual health side it lists tadalafil, sildenafil and vardenafil as separate products rather than combining them into one tablet — a choice that, after finding two providers in this same queue stacking PDE5 inhibitors, reads as sound clinical judgement. Two things hold it back. No pricing appears anywhere we could reach, so 'No Hidden Fees' cannot be assessed against any actual figure. And a board-certified plastic surgeon is a genuine credential but not a specialist one for metabolic medicine or endocrinology, which is worth knowing rather than being a criticism in itself.

RxSpan MD advertises physician-reviewed treatment plans and doctor-led plans with coaching. Ask at this stage which route — compounded, brand-name or microdosed — is being recommended and why.

Provider Involvement
Better disclosed than most, at least at the top. Dr John Diaz is named as the founding physician with a stated board certification and two decades of practice, and the service advertises doctor-led plans with coaching and physician-reviewed treatment plans. What is not published is who else prescribes, what monitoring cadence applies, or whether any laboratory work is required. Note also that plastic surgery is not a specialty in obesity medicine, endocrinology or metabolic health — that does not disqualify a physician from prescribing GLP-1s, but a patient choosing a provider on clinical grounds should know it.
Lab Requirements
None published. Ask what baseline and ongoing monitoring applies to your protocol.
Pharmacy Fulfillment
Not named. RxSpan MD offers both compounded and brand-name GLP-1s but does not identify its compounding pharmacy or state its 503A or 503B status. Ask before ordering compounded product.
Shipping Frequency
Free expedited delivery. Cadence and window not published.

Pros
- Names its founding physician — Dr John Diaz, a board-certified plastic surgeon with 20+ years of experience

- Advertises doctor-led plans with coaching and physician-reviewed treatment plans
- States 'No Hidden Fees' and includes free expedited delivery
- Covers weight loss, longevity, hair and sexual health on one platform
Cons
- No pricing published anywhere on the pages we could reach
- The named physician is a plastic surgeon rather than an obesity medicine or endocrinology specialist
- Also sells NAD+, sermorelin and glutathione on longevity claims the evidence does not support
- No published cancellation policy, refund terms, state list, BMI criteria or lab requirements
- No named compounding pharmacy
- Little independent review record to corroborate the on-site claims
Who RxSpan MD May Be Best For
- Patients who want a named physician behind the service rather than anonymous providers
- People who want the option of brand-name or microdosed GLP-1s as well as compounded
Limitations
- No published pricing at all
- No cancellation, refund, state, eligibility or lab disclosure
- Longevity products sold on unevidenced claims
- Founding physician's specialty is not metabolic medicine
Reputation & Trust
RxSpan MD gets the most important accountability question right and the most important commercial one wrong. Naming Dr John Diaz as the founding physician, with a stated board certification and 20 years of practice, puts a checkable person behind the service — set that against the anonymous 'licensed providers' and 'certified medical professionals' formulations used almost everywhere else in this directory, and it is a meaningful difference. Offering compounded, brand-name and microdosed GLP-1 routes rather than one, and pricing tadalafil, sildenafil and vardenafil as separate products rather than stacking PDE5 inhibitors into a single tablet as two other providers in this queue do, both suggest reasonable clinical judgement. But no price appears anywhere, which makes 'No Hidden Fees' an unfalsifiable claim, and the standard disclosures are all absent: no cancellation terms, no refund policy, no state list, no eligibility criteria, no lab requirements, no named pharmacy. The NAD+, sermorelin and glutathione line carries the usual longevity framing that the evidence does not support. And a plastic surgery background, while a real credential, is not specialist training in metabolic medicine — worth knowing when the practice's stated purpose is extending healthspan through prescribed medication.
What Makes RxSpan MD Different
- Names a checkable board-certified founding physician
- Compounded, brand-name and microdosed GLP-1 routes all offered
- PDE5 inhibitors sold separately rather than combined
- Doctor-led plans with coaching included
Our Verdict
RxSpan MD earns 3.5/5. It does the single most unusual thing in this directory: it tells you who the doctor is. Dr John Diaz is named as the founding physician with a stated board certification and 20 years of practice, and the site explains how the practice came about — set that against the anonymous 'licensed providers' language used almost everywhere else here, and it is real accountability. The clinical structure is sensible too: compounded, brand-name and microdosed GLP-1 routes rather than one, and tadalafil, sildenafil and vardenafil sold as separate products rather than stacked into a single tablet, which two other providers in this same queue do against approved-labelling guidance. What we cannot get past is that nothing is priced. 'No Hidden Fees' is advertised, but with no published figures at all there is no way to test it, and no cancellation terms, refund policy, state list, eligibility criteria or lab requirements appear either. The longevity range carries the usual unevidenced framing. And while a plastic surgeon is a fully qualified physician, it is not specialist training in metabolic medicine — worth knowing for a practice built on extending healthspan through prescription. Promising structure; ask for the numbers before committing.

Frequently Asked Questions
What does RxSpan MD cost?
We could not find out. No prices are published for any product on the pages we could reach, despite the service advertising 'No Hidden Fees'. Cost is disclosed during the consultation. Ask for a full written quote covering medication, any recurring charge and shipping before providing payment details — and compare it against providers like Aspire Health that publish complete dose-by-dose ladders.
Who is the doctor behind RxSpan MD?
Dr John Diaz, identified on the site as a board-certified plastic surgeon with more than 20 years of experience, who founded the practice after patients seeking aesthetic treatment also asked for guidance on weight and wellness. Naming a checkable physician is genuinely unusual here and to the practice's credit. It is also fair to note that plastic surgery is not a specialty in obesity medicine or endocrinology.
Does RxSpan MD offer brand-name GLP-1s?
Yes. It lists compounded GLP-1, brand-name GLP-1 and a microdosing option, so you are not restricted to compounded product. That matters, because compounded semaglutide and tirzepatide are not FDA-approved while brand-name Wegovy, Ozempic, Mounjaro and Zepbound are. Ask which specific brand-name products are available and at what price.
Are the NAD+ and sermorelin products worth buying?
We would be sceptical. NAD+, sermorelin and glutathione are compounded products marketed on longevity and recovery claims that the published evidence does not firmly support, and none is FDA-approved for those uses. They are also outside the scope of weight management, which is what most readers arrive here for.
