RNK Health Review: One Price With Everything Included — And a Guarantee That Covers Almost None of It

What Is RNK Health?

RNK Health, trading online as MYRNK, is a telehealth platform selling compounded longevity and wellness treatments on monthly subscriptions. Its catalogue spans NAD+ in liposomal and nasal forms, sermorelin, B12 injections, testosterone-support products including enclomiphene, a naltrexone-based craving product, GLP-1 weight-loss medication and DNA testing.

The pricing structure is genuinely clean on paper. A $129/month entry tier covers liposomal NAD+, sermorelin, B12 and testosterone support, with higher tiers at $189, $197 for nasal NAD+ and $297 for the craving product. RNK describes this as a single subscription price including the medication, access to coaching and clinician consultations, with no hidden fees and shipping included — which is a better structure than the membership-plus-medication stacking used by several competitors.

The company launched in March 2026, making it roughly five months old at the time of this review. We could find no BBB profile for it. We also want to be clear about something we checked and did not find: a June 2026 FDA warning letter that appears near this brand in search results was addressed to Roen Health, Inc. dba RoenRx — a different company entirely. We found no FDA warning letter directed at RNK Health.

What we did find is a guarantee that does far less than the marketing suggests, and a set of complaints about being billed for products that did not arrive. Both are set out below.

Products & Pricing

Prices are drawn from RNK's own site data as at 7 August 2026. The tiering is easy to misread: $129/month is the entry point across several products, but nasal NAD+ is $197 and the naltrexone craving product $297, so the headline figure does not describe the catalogue. A promotional code offering $240 off appears in the site's own data, which suggests heavy discounting on longer commitments — check what happens to your price after any introductory period, because the complaint record here concerns billing rather than pricing transparency.

Regulatory Status and What the Evidence Supports

Everything RNK sells in these categories is compounded. Compounded medications are not FDA-approved and are not reviewed by the FDA for safety, effectiveness or quality before marketing.

The evidence position varies enormously across the catalogue and the pricing does not reflect it. Enclomiphene for raising natural testosterone is an off-label but recognised clinical approach with a plausible mechanism. Naltrexone has genuine evidence in appetite and craving contexts, though prescribing it alone off-label for weight is a different proposition from the approved naltrexone-bupropion combination. B12 is genuinely useful — if you are deficient, and does nothing if you are not.

NAD+ is where the marketing runs furthest ahead of the evidence. Most published human research concerns oral precursors such as nicotinamide riboside and NMN, and even that shows biomarker changes rather than demonstrated improvements in energy, cognition or ageing. Controlled outcome trials of injected NAD+ in healthy adults are essentially absent. The nasal formulation at $197/month is weaker still: intranasal absorption of NAD+ has not been meaningfully studied, and paying a 53% premium over the injectable for a route with no absorption data is difficult to justify on anything but convenience.

Sermorelin carries an additional caution rather than merely an evidence gap. It is a growth hormone-releasing hormone analogue with no FDA approval for adult body composition, sleep or recovery use, and it acts on the growth hormone/IGF-1 axis, which is implicated in cell proliferation — so it warrants real care in anyone with a history of cancer, and can affect glucose tolerance.

The Consultation Process

Eligibility

• •Eligibility is determined by an independent licensed provider from your online intake. No lab work is described as a requirement.
• •States served are not published on the pages we reviewed. Confirm before subscribing.
• •Sermorelin and other growth-hormone-axis products should not be used by anyone with an active malignancy, and warrant real caution in anyone with a cancer history because the growth hormone/IGF-1 pathway is involved in cell proliferation. They can also worsen glucose tolerance.
• •Enclomiphene is an off-label use in men and can cause visual disturbance, mood changes and headache. Testosterone-related treatment should be based on measured hormone levels — an early-morning serum sample, confirmed on a second — rather than symptoms alone, and no lab requirement is described here.
• •Naltrexone must not be taken by anyone using opioids, and can precipitate acute withdrawal in anyone opioid-dependent. It also requires caution in liver disease.
• •GLP-1 medicines are contraindicated with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2, and in pregnancy or while trying to conceive.
• •B12 supplementation is genuinely beneficial in deficiency and does nothing for energy in people with normal levels. Deficiency is diagnosed by a blood test, which this service does not require.
• •None of these products should be understood as treatment for a diagnosed condition. Persistent fatigue, low mood or unexplained body composition change deserve a proper workup — thyroid, iron, B12, sleep apnoea, depression, testosterone — before a subscription aimed at symptoms nobody has measured.

Clinicians, Lab Testing & Pharmacy

Shipping & Support Services

Shipping is included in the subscription price. It is also the weakest part of the service on the public record. Complainants describe NAD+ orders arriving late, leaking, and with damaged bottles — and in more serious cases not arriving at all. One reports paying $378 for three months of NAD+ supplies that were never received; another reports being charged $269 for two months and never receiving the November shipment. For an injectable product, packaging failures are not a cosmetic complaint.

• •Single subscription price covering medication, coaching, clinician consultations and shipping
• •No separate membership or consultation fee
• •Entry pricing at $129/month across several products
• •Both injectable and nasal NAD+ formats offered
• •Broad catalogue including testosterone support, B12, craving management and GLP-1s
• •Clinician consultations included rather than charged per visit
• •Coaching bundled into the price

Fees, Cancellation & Refunds

Insurance & HSA/FSA

Pros & Cons

Who RNK Health May Be Best For

• •Few readers on the current record — the guarantee carve-out and fulfilment complaints outweigh the pricing structure
• •People who specifically want enclomiphene or naltrexone and have confirmed the price and cancellation terms in writing
• •Anyone who proceeds should pay with a disputable card and verify that each shipment actually arrives before the next charge

Limitations

• •The guarantee is the problem, and it is a problem of framing rather than of the terms themselves. A 100% money-back guarantee is a powerful thing to put on a landing page. Discovering afterwards that it covers only semaglutide and tirzepatide — and not the NAD+ or sermorelin that most of this catalogue consists of — means the reassurance that prompted the purchase does not apply to the purchase. Even where it does apply, six months of documented adherence with time-stamped photographs is a demanding evidentiary bar.
• •The fulfilment complaints are more serious than ordinary shipping grumbles. Paying $378 for three months of NAD+ and receiving none, or being charged $269 across two months with a shipment never delivered, describes money taken for goods not supplied. The reported explanation — that customers are billed whether or not they receive product — would, if accurate, describe a subscription decoupled from fulfilment entirely. Combined with no refunds after shipping, that leaves very little protection.
• •On the products themselves, the pricing runs opposite to the evidence. Nasal NAD+ at $197/month costs 53% more than the injectable at $129, and intranasal absorption of NAD+ has not been meaningfully studied — you are paying a premium for a route nobody has shown works. Injectable NAD+ is barely better supported. The items with the most plausible mechanisms, enclomiphene and naltrexone, sit at the cheap and expensive ends respectively without that reflecting evidence quality.
• •Prescribing testosterone support, a growth-hormone-axis peptide and B12 without any lab work is the clinical weak point. All three are situations where the right answer depends on a measured baseline: testosterone deficiency is a laboratory diagnosis, B12 supplementation helps only in deficiency, and sermorelin warrants caution in anyone with a cancer history. A questionnaire establishes none of that.
• •In fairness, the commercial architecture is genuinely good — one price, no membership stacking, coaching and clinician access included, shipping covered. If the guarantee matched its billing and the shipments arrived reliably, this would rate considerably higher. At five months old with no BBB profile, there is not yet enough record to know whether the complaints are teething problems or the model.

Alternatives to Consider

Frequently Asked Questions

Our Verdict

RNK Health has built its pricing the way this market should: one subscription covering the medication, the clinician consultations, the coaching and the shipping, with no membership fee stacked on top and a $129 entry point. That is cleaner than most competitors, and some reviewers describe the service as responsive and professional.

The guarantee undoes much of the goodwill. A '100% Money-Back Guarantee' displayed prominently, which on inspection covers only semaglutide and tirzepatide — not the NAD+ and sermorelin that make up most of the catalogue, and not DNA testing — is reassurance aimed at a purchase it does not protect. Even for the GLP-1s it requires six months of adherence evidenced by time-stamped photographs. And once anything ships, there is no refund at all.

That matters more because of what the complaint record contains. Customers describing $378 paid for three months of NAD+ never received, $269 charged with a shipment that never came, and being told they are billed whether or not product arrives, are not describing slow delivery — they are describing paying for nothing. Reports of bottles arriving leaking and damaged are a separate concern for an injectable.

On the products, the pricing inverts the evidence. Nasal NAD+ at $197 costs half again as much as the injectable at $129, for a route whose absorption has not been meaningfully studied. Sermorelin has no approval for the uses it is sold for and needs real caution in anyone with a cancer history. And selling testosterone support and B12 with no lab work means nobody establishes whether you needed either.

We rate RNK Health 2.1 out of 5. Good commercial architecture, a guarantee that does not cover what it appears to, fulfilment complaints that involve money rather than inconvenience, and five months of history with no independent record to check. If fatigue, sleep or body composition is the real problem, Hone Health's $65 biomarker panel will tell you what is actually going on before you spend $129 a month on a hypothesis.
