RNK Health review: big promises, and a headline price that isn't the monthly one
RNK Health sells GLP-1s, NAD+ and sermorelin with unusually loud copy. Tirzepatide makes hunger disappear instantly. NAD+ clears brain fog instantly. Sermorelin builds muscle and shreds belly fat. None of that matches the trials. Its prices need care too. On the NAD+ and sermorelin pages, the "one price" in large type is a six-month plan, and paying month to month costs $169.

Provenance
What RNK Health 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.
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 injection — Advertised from $197 a month. The page shows no plan options, so ask whether that's the monthly rate or a prepaid one.
- Compounded tirzepatide injection — Advertised from $297 a month, with no plan options shown on the page.
- Compounded NAD+ injection — $169 a month if you pay monthly. The $129 headline is the six-month plan, billed as one charge.
- Compounded sermorelin injection — $169 a month billed monthly. The $129 figure in large type is the six-month plan, one charge of $774.
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.

The comparison
What they claim, against what the trials show
Each claim below is quoted word for word from RNK Health’s own page. Tap a row to see the quote, the trials behind it, and why it got that verdict.
Compounded semaglutide injectionSemaglutide · Compounded (503A)Claim reaches past the trials
“Effortless Weight Loss: Shed pounds by naturally curbing your appetite. Kill Cravings: Stop thinking about food all day long. Keep the Muscle: Burn fat while staying strong and toned.”
Read on the RNK Health site, September 2026
Phase 3 trials
What the trials show for Semaglutide
- NCT03548935 STEP 1 — Phase 3, completed, n=1,961. 68 weeks in 1,961 adults on semaglutide 2.4 mg, including 16 weeks of dose escalation, alongside a lifestyle program.
Semaglutide does curb appetite, and STEP 1 showed real weight loss. The trouble is the word effortless. Everyone in STEP 1 took the drug alongside a lifestyle program, and the result was measured after 68 weeks. RNK's homepage says noticeable loss typically comes within the first month, when the trial was still in its first low doses. Keeping the muscle is asserted with nothing behind it on the page.1
Compounded tirzepatide injectionTirzepatide · Compounded (503A)Claim reaches past the trials
“The Ultimate Weight Loss: Lose more weight, faster than other treatments. Total Craving Control: "Food noise" and hunger disappear instantly. Supercharge Metabolism: Force your body to burn fat for fuel.”
Read on the RNK Health site, September 2026
Phase 3 trials
What the trials show for Tirzepatide
- NCT04184622 SURMOUNT-1 — Phase 3, completed, n=2,539. 72 weeks at 5, 10 and 15 mg once weekly, including a 20-week dose-escalation period.
Tirzepatide is a strong drug, and SURMOUNT-1 is one of the best weight-loss trials ever run. Nothing in it happened instantly. The dose was raised over 20 weeks and the result was read at 72. Hunger disappearing instantly is not something any trial measured, and forcing the body to burn fat is a slogan, not a finding. The page also calls it the strongest tool on the market, on a site that sells a compounded version of it.2
Compounded NAD+ injectionNicotinamide adenine dinucleotide (NAD+) · Compounded (503A)No trial supports this claim
“Experience NAD's Proven Benefits: Endless Energy: Kill the afternoon crash. Improve Mood & Motivation. Laser Focus: Clear the brain fog instantly. Age Backwards: Repair your cells from the inside out.”
Read on the RNK Health site, September 2026
No trial for this use
No trial has tested injected NAD+ for energy, focus, mood or aging in healthy adults. A PubMed search in August 2026 for NAD+ given by injection or infusion, limited to randomized trials, found one study that actually gave it: a week of low-dose infusions in people with heart failure from ischemic cardiomyopathy, measuring heart function. Nothing in that literature measures the benefits RNK lists.
The heading says proven benefits, and nothing on the page is proven. The one randomized trial of injected NAD+ was in heart failure and measured how well the heart pumped, over a single week. Clearing brain fog instantly and aging backwards are not claims any study has tested. The explanation beside them, NAD+ as a battery your body refills, is a fair picture of the chemistry. It says nothing about what an injection does for you.3
Compounded sermorelin injectionSermorelin · Compounded (503A)Claim reaches past the trials
“Build muscle, shred belly fat, and wake up with more energy. Get More Lean Muscle. Burn Stubborn Fat. Have All-Day Energy. Sleep deep & Wake up ready to crush the day. Sermorelin flips the switch back on. It tells your body to act young again.”

No trial for this use
What the trials show for Sermorelin
Searched August 2026. ClinicalTrials.gov holds no completed study that actually gave sermorelin; the records that match it by name used other drugs or used growth-hormone-releasing hormone as a one-off diagnostic test. PubMed returns 19 randomized trials for sermorelin, the latest from 2005, almost all measuring hormone levels or growth in children. The closest to this use is a 1997 trial of a near-identical molecule in 19 adults aged 55 to 71.
Sermorelin does prompt the pituitary to release growth hormone, so the premise is real. The results promised on top of it are not. In the 1997 trial, 16 weeks of nightly injections raised lean mass in the nine men and not in the ten women. Body weight didn't change, nothing else in body composition changed, and sleep quality was unaffected in both sexes. So the muscle claim rests on nine men, the belly-fat claim has nothing under it, and the sleep claim runs against the one measurement that exists.4,5

Who actually fills your prescription

RNK prints a pharmacy address in Springville, Utah, and a pharmacy phone number at the bottom of every page, but never the pharmacy's name. Its terms say an independent licensed pharmacy prepares, compounds and ships the medication, and that RNK doesn't control it. The doctors come through named medical groups, OpenLoop Healthcare Partners and MD Integrations among them. So you can tell who prescribes, and where the drug ships from, without being told who makes it.

Verdict
The bottom line
Treat the copy as advertising, not information. None of the instant results it promises showed up in any trial. If you buy, budget $169 a month for NAD+ or sermorelin, not the $129 in large type. On the GLP-1s, find out whether $197 is a monthly or a prepaid rate before you pay, because the page doesn't say.

The copy
Here's what RNK's product pages promise:
- Tirzepatide: "Food noise" and hunger "disappear instantly."
- NAD+: "Clear the brain fog instantly." "Age Backwards."
- Sermorelin: "Build muscle, shred belly fat."
- Semaglutide: "Effortless Weight Loss."
The trials behind the two GLP-1s are real and strong. 1 2 They also took months. SURMOUNT-1 raised the dose over 20 weeks and read the result at 72. Nothing in it was instant.
For NAD+ and sermorelin there's much less to go on. The one randomized trial of injected NAD+ was a week of infusions in heart failure. 3 The closest sermorelin trial, from 1997, found more lean mass in men only, no change in weight and no change in sleep. 5
Full analysis — 2 more sectionsThe price in large type · Before you pay
The price in large type
The NAD+ page says:
“One Price. Zero Hassle. $129 — Everything. Included.”
Scroll down and there are three plans:
- Monthly: $169, billed monthly
- Three months: $149 a month, billed every three months
- Six months: $129 a month, billed every six months
So the one price is the six-month plan, taken as a single $774 charge. The sermorelin page works the same way.
The GLP-1 pages use the same "One Price" block, at $197 for semaglutide and $297 for tirzepatide. They show no plans underneath. The quiz asks for your name, phone and email before it gets any further, and the FAQ says full pricing appears at checkout. You can't tell from outside which kind of price it is.
Before you pay
Once you submit the intake form, the fee is final and non-refundable unless a clinician finds you ineligible. Cancel at least 72 hours before a billing date, or that cycle is charged. RNK does promise an email a week before every rebill, which helps.
Questions
Frequently asked questions
What does RNK Health really cost?
For NAD+ or sermorelin, $169 a month if you pay monthly. The $129 figure it leads with is a six-month plan paid as one charge of $774. For the GLP-1s, the pages say from $197 and $297 but show no plan options.
Does tirzepatide really stop hunger instantly?
No trial measured that. In SURMOUNT-1, the dose was raised gradually over 20 weeks and weight loss was measured after 72. Appetite does drop on the drug, but not overnight.
Will sermorelin build muscle and burn fat?
The evidence is thin. The closest trial, 19 older adults in 1997, found more lean mass in the men only, no change in body weight, and no change in sleep. Nothing supports shredding belly fat.
Can I get a refund?
Only in narrow cases. RNK's policy makes the fee non-refundable once you submit the intake, except if a clinician finds you ineligible or your order arrives damaged or wrong. Cancel 72 hours before a billing date to avoid the next charge.
Who makes the medication?
RNK doesn't say. Every page prints a pharmacy address in Springville, Utah, and a phone number, but not the pharmacy's name. Its terms say an independent licensed pharmacy compounds and ships it.

Claims read first-party
Every quoted claim was read off RNK Health'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.
