Rex MD review

By Priya Anand · Aminoscope

Real labs, blended price

Our verdict

Rex MD's sermorelin sits inside its testosterone program rather than in a longevity catalog, and that placement comes with a stricter gate than questionnaire-only sellers use: a real lab panel at Quest or LabCorp or an at-home kit, then a video consultation, before anything is prescribed.

Main trade-offs

  • No sermorelin-specific price — the $250 to $299 monthly range spans four different medications
  • The sermorelin page contradicts itself on frequency: five times a week in the summary, once daily in the body

Full assessment

Rex MD's sermorelin sits inside its testosterone program rather than in a longevity catalog, and that placement comes with a stricter gate than questionnaire-only sellers use: a real lab panel at Quest or LabCorp or an at-home kit, then a video consultation, before anything is prescribed. Compared with a five-minute questionnaire, that is worth a great deal. What you cannot get is a sermorelin price — the program charges $99 once and then $250 to $299 a month depending on which of four medications is prescribed, without saying which lands where, so the range is a program price, not a molecule price.

What it is

Rex MD is a large US men's telehealth platform with categories spanning sexual health, weight loss, sleep, hair loss, premature ejaculation and testosterone. Sermorelin is one of four options inside its Testosterone Program, alongside testosterone cypionate injection, testosterone gel and Clomid (clomiphene citrate). Its weight-loss line is built around branded GLP-1s such as Wegovy, with compounded medication mentioned as an option where a provider finds it appropriate. It states coverage in all 50 states, runs the testosterone program without insurance, and says it is LegitScript-certified. Its sermorelin page is explicit that the product is compounded and not FDA-approved.

How care works

Questionnaire, then bloodwork, then a video consultation, then prescribing — in that order. You answer a dynamic online questionnaire about symptoms and history; once prequalified, you complete lab work at a local Quest or LabCorp facility or with an at-home kit; then you have a virtual consultation with a Rex MD-affiliated provider who decides whether treatment is appropriate. Requiring an actual panel before a growth-hormone secretagogue or a testosterone product is the correct clinical standard and it is the main reason to consider this program for sermorelin at all. The program then continues with new labs 90 days after you start, labs every six months after that, and a video call with your provider at least once a year, which is a real monitoring cadence rather than a repeat-billing arrangement. Two things to be aware of. Sermorelin is framed as a testosterone-support option, and the page is not consistent about how far that goes: its summary says sermorelin "may help support energy levels, overall vitality, and testosterone levels," while the body text retreats to improved growth hormone that "may positively influence factors associated with low testosterone." Neither is the same as raising testosterone, and the body text is the more accurate of the two. And the page contradicts itself on dosing: the summary panel says the injection is given five times a week while the body text says it is typically administered once daily before bedtime. Ask which it is, because it changes what a month contains and what it costs you in vials.

Costs, billing and cancellation

Program-level, not molecule-level, and that distinction is the whole story. The Testosterone Program starts with a one-time $99 fee, shown as discounted from $199, covering the initial lab tests and a consultation with a licensed provider. For patients who are then prescribed, the monthly subscription includes the medication and ranges from $250 to $299 depending on which medication is prescribed, with subsequent lab tests covered by that fee. Because that range spans four different medications — testosterone cypionate, testosterone gel, Clomid and sermorelin — and the site does not say which sits where, it does not tell you what sermorelin specifically costs. Treat the range as a program price, not a sermorelin price, and ask for the sermorelin figure before you pay the $99. What the structure does get right is that ongoing labs are inside the monthly figure, which on a therapy requiring monitoring is the inclusion that matters. The testosterone program does not use insurance. Its weight-loss program is separate and is pitched around insurance copays for branded GLP-1s, which tells you nothing about a peptide price.

Medication and evidence

Compounded; not FDA-approved. Prescription required only if a licensed provider finds it appropriate. Rex MD states this plainly in the safety panel on its own sermorelin page — that sermorelin is a compounded drug that is not FDA-approved but may be prescribed where appropriate — which is exactly the right disclosure in exactly the right place, and it still means the preparation has not been reviewed by the FDA for purity and potency the way approved drugs are. It also flags that heart-rate and blood-pressure changes may occur with inadvertent overdosage. On the evidence, sermorelin is a synthetic GHRH analog that stimulates the pituitary to secrete growth hormone, preserving the feedback loop that injected HGH bypasses; the mechanism is real and well described, and the long-term human outcome data behind the energy, vitality and body-composition claims stays thin. The claimed link to testosterone is thinner still — raising growth hormone is not a testosterone therapy, and the page's own wording concedes as much. The rest of the program is better grounded: testosterone cypionate is FDA-approved and testosterone replacement has a large randomized safety base, with real monitoring obligations around hematocrit, PSA and testosterone levels and suppression of natural production and fertility, which is precisely why the lab gate exists. Clomiphene raises endogenous testosterone by blocking estrogen feedback at the pituitary and preserves fertility, but is not FDA-approved for that use in men. Individual results vary.

Pros and watch-outs

What we like

  • Requires a real lab panel at Quest or LabCorp or an at-home kit, plus a video consultation, before prescribing
  • States on the sermorelin page itself that the product is compounded and not FDA-approved
  • Follow-up labs at 90 days and every six months, plus a yearly video call, are stated as covered by the monthly fee
  • $99 one-time start covers the initial labs and the consultation, so the diagnostic step is priced openly
  • All 50 states, a stated LegitScript certification, and four distinct treatment routes inside one program

Watch-outs

  • No sermorelin-specific price — the $250 to $299 monthly range spans four different medications
  • The sermorelin page contradicts itself on frequency: five times a week in the summary, once daily in the body
  • The page's summary says sermorelin may support testosterone levels, a stronger claim than its own body text makes
  • The testosterone program is cash-pay only, and the surrounding site is heavily ED- and promotion-led
  • Marketed exclusively to men through a men's-health platform

Best for

Men who want sermorelin prescribed only after bloodwork and a video consultation, with ongoing labs inside the monthly cost.

Who should look elsewhere

Anyone who needs to know what sermorelin alone costs before starting, anyone wanting NAD⁺ or a repair peptide, or anyone who does not want to be inside a testosterone program to get it.

Frequently asked

What does sermorelin cost at Rex MD?
Rex MD does not publish a sermorelin price. The Testosterone Program starts at a one-time $99 covering the initial labs and a provider consultation, and then runs $250 to $299 a month depending on the medication prescribed, with later labs covered — but that range spans testosterone cypionate, testosterone gel, Clomid and sermorelin without saying which costs what, so it is a program price, not a molecule price.
Do I have to get bloodwork first?
Yes, and that is the strongest thing about this program. After the online questionnaire you complete lab work at a local Quest or LabCorp facility or with an at-home kit, then have a virtual consultation with an affiliated provider before anything is prescribed, rather than shipping after a questionnaire alone.
How often do I inject sermorelin here?
The page says both. Its summary panel states a subcutaneous injection given five times a week; its body text says injections are typically administered once daily, often before bedtime. That is a real contradiction on Rex MD's own page and it changes how many vials a month costs you — ask your provider to confirm the schedule in writing before your first shipment.
Will sermorelin raise my testosterone?
Do not count on it. The page's summary says sermorelin may help support testosterone levels, but its own body text retreats to improved growth hormone that may positively influence factors associated with low testosterone — a hedge, not a testosterone effect. Sermorelin acts on the growth-hormone axis; if low testosterone is the problem, the testosterone and clomiphene options in the same program are the routes that address it directly.
Is Rex MD legit?
Rex MD is a peptide telehealth service you reach through a video visit with a clinician. Its stated availability: All 50 states. What it publishes up front: $99 one-time start covering a lab panel and video consult; program then $250–$299/mo depending on medication, labs included. It is cash-pay and states it does not bill insurance. It shows a LegitScript seal. Ask the company for its certificate number before you rely on it. Before you pay, ask in writing about a single monthly price you can check before an intake and which medications it dispenses.
