Rex MD review

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 runs branded semaglutide and Zepbound vials rather than compounded GLP-1, it states coverage in all 50 states, it does not bill insurance, and it holds LegitScript certification. Its sermorelin page is explicit that the product is compounded and not FDA-approved.

How it 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 this entry exists on the peptide board at all. The program then continues with quarterly shipments, ongoing lab tests and a stated minimum of one video consult a year, which is a real monitoring cadence rather than a repeat-billing arrangement. Two things to be aware of. Sermorelin is framed throughout as a testosterone-support option, with the page suggesting improved growth hormone "may positively influence factors associated with low testosterone" — a hedged claim that is not the same as raising testosterone, and worth reading as the hedge it is. 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.

Pricing transparency

Program-level, not molecule-level, and that distinction is the whole story. The Testosterone Program starts with a one-time $99 purchase covering a lab panel and a video consultation with a provider or nurse practitioner. For patients who are then prescribed, the program is described as costing as low as $250 a month, covering quarterly shipments of the prescribed treatment, ongoing lab tests and a minimum of one video consult a year. Because that $250 floor spans four different medications — testosterone cypionate, testosterone gel, Clomid and sermorelin — it does not tell you what sermorelin specifically costs, and it may not be the tier sermorelin lands in. We are not quoting it as a sermorelin price and neither should anyone else. 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. Its GLP-1 program is separate at roughly $199 a month for branded semaglutide and around $349 for Zepbound vials rising with dose — those are weight-loss numbers and are not a peptide price. No insurance is billed.

Branded vs compounded

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 analogue 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 randomised safety base, with real monitoring obligations around haematocrit, 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 oestrogen feedback at the pituitary and preserves fertility, but is not FDA-approved for that use in men. Individual results vary.

Pros and watch-outs

The evidence behind what Rex MD prescribes

We grade the molecules, not the marketing. Here is what the human data actually shows for each thing on their menu.

• Sermorelin: a real GHRH drug, read against the anti-aging pitch

  An approved growth-hormone-releasing analog with a pediatric track record — and a longevity case built more on biomarkers than outcomes.

• TRT: what testosterone therapy is actually proven to do

  An FDA-approved therapy for diagnosed hypogonadism — with real but moderate benefits (sexual function, mood; not vitality), cardiovascular non-inferiority in TRAVERSE, and a real fertility trade-off.
