MYRNK Review : NAD+ & Sermorelin Longevity Therapy — Is It Worth It?

Quick Verdict

Our Rating: 7.9/10 — Very Good

Best For: Individuals serious about longevity, energy optimization, and cellular health who want clinician-guided NAD+ injectable therapy or Sermorelin — delivered directly to their door with 1-on-1 coaching support across all 50 states.

If you have been researching GLP-1 weight loss platforms, you have probably noticed that most of them offer the same thing: a Semaglutide prescription, a telehealth consultation, and home delivery. MYRNK is different.

Operated by RNK Health, MYRNK has built its reputation around two treatments that most telehealth platforms completely ignore: NAD+ injectable therapy and Sermorelin — two of the most talked-about longevity and performance optimization tools in 2026. Weight loss is part of the picture too, but at MYRNK, the bigger draw is helping patients address energy and cellular health alongside their weight loss goals.

With 300+ Trustpilot reviews and active responses from their team, MYRNK has built a real patient community — though as with many compounded-medication telehealth platforms, reviews reflect both genuine strengths and some recurring complaints worth knowing about before you subscribe.

Why NAD+ and Sermorelin Are the Real Story Here

Before diving into how MYRNK works, it is worth understanding why NAD+ and Sermorelin have become two of the most talked-about treatments in the longevity space:

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of the human body, playing a role in energy metabolism, DNA repair, and cellular function. NAD+ levels are known to decline with age. That said, it’s worth noting that current published research characterizes NAD+ precursors as promising but still-emerging adjuncts rather than established anti-aging therapies — so it’s reasonable to keep expectations realistic.

Sermorelin is a growth hormone-releasing peptide that stimulates the pituitary gland to produce more natural growth hormone, offering a more physiologically gradual approach than synthetic HGH. One practical note: Sermorelin is classified as a prohibited substance under the WADA 2026 Prohibited List, so competitive athletes should discuss this with both their clinician and their sport’s anti-doping authority before starting.

How It Works

MYRNK’s telehealth process is fully remote and designed to get patients started quickly:

  1. Free Online Quiz: You complete a short quiz sharing your goals — from weight loss to energy and focus — and MYRNK recommends a personalized path.
  2. Licensed Clinician Evaluation: Independent licensed clinicians (through the OpenLoop Healthcare Partners network) review your information and determine whether treatment is appropriate, then prescribe if suitable.
  3. Flexible Delivery Formats: NAD+ is available in multiple delivery formats (injectable, nasal, liposomal liquid), giving patients flexibility in how they administer treatment at home.
  4. 1-on-1 Coaching: You work with a personal RNK coach to track progress and make adjustments along the way.

The Pros & Cons

What We Like (Pros):

  • NAD+ in Multiple Formats: MYRNK offers NAD+ injectable, nasal spray, and liposomal liquid options — more delivery flexibility than most competitors offer.
  • Sermorelin for Performance & Recovery: A clinically recognized, physiologically gradual approach to supporting natural growth hormone levels — something most GLP-1-only telehealth platforms don’t offer.
  • 1-on-1 Coaching Included: Personal coaching is built into the program, adding accountability beyond just receiving medication.
  • Accessible Starting Price: NAD+ and Sermorelin programs both start from $129/month — competitive for clinician-guided injectable therapy with home delivery.
  • GLP-1 Weight Loss Also Available: Compounded Semaglutide (from $197/month) and Tirzepatide (from $297/month) are available for patients who want to combine weight loss with longevity therapy.
  • GLP-1 Money-Back Guarantee: MYRNK offers a 100% money-back guarantee specifically for GLP-1 medications, for patients who document six months of adherence.
  • 50-State Reach: RNK Health collaborates with labs and pharmacies across all 50 states for delivery.

What to Consider (Cons):

  • Cold-Chain Shipping Complaints: Multiple verified reviewers report temperature-sensitive medications (NAD+, Sermorelin) arriving without proper cold packing in warm weather. If you order, ask about cold-chain shipping safeguards and inspect your package on arrival.
  • Money-Back Guarantee Doesn’t Cover NAD+ or Sermorelin: The 100% money-back guarantee applies only to GLP-1 medications — it explicitly does not extend to NAD+, Sermorelin, or DNA testing.
  • Dosage-Related Complaints: Some reviewers report their requested NAD+ dosage (e.g., 2400mg) was changed or delayed pending additional documentation after signup — clarify your exact dosage and any conditions in writing before subscribing.
  • Mixed Billing/Cancellation Reviews: Some reviewers cite billing and refund friction; cancellation requires two days’ notice before your billing date. Read the full refund and cancellation policy carefully.
  • NAD+ Is Still Emerging Science: Published research treats NAD+ precursors as promising but experimental rather than established anti-aging therapy — set realistic expectations.
  • Compounded Medications: MYRNK’s NAD+ and Sermorelin are compounded prescriptions, not FDA-approved finished products.

Pricing Breakdown

MYRNK/RNK Health operates on a subscription model with treatment-specific pricing (per the company’s published rates; always verify current pricing before enrolling, as it may change):

  • NAD+ Injectable, Nasal, or Liposomal Liquid: Starting from $129/month.
  • Sermorelin: Starting from $129/month.
  • Compounded Semaglutide: Starting from $197/month (oral option from $198/month).
  • Compounded Tirzepatide: Starting from $297/month.
  • Enclomiphene (testosterone support): Starting from $189/month.
  • DNA Blueprint Testing: $399, covering 80+ biomarkers.
  • Pricing includes medication, clinician consultation, and coaching access, with no published membership fee separate from treatment cost.

Who Is MYRNK Best For?

MYRNK is an excellent choice if you:

  • Want clinician-guided NAD+ injectable, nasal, or liposomal therapy for energy and cellular support
  • Are interested in Sermorelin for natural growth hormone support and recovery
  • Want 1-on-1 coaching alongside your clinical treatment
  • Are looking to combine GLP-1 weight loss with longevity therapy in one platform
  • Are comfortable verifying cold-chain shipping practices and reading refund terms carefully before subscribing

It may not be the right fit if you want a simple low-cost GLP-1 prescription only, if a broad money-back guarantee across all treatments matters to you, or if billing transparency and easy cancellation are your top priorities.

Final Thoughts

For patients ready to move beyond standard weight loss prescriptions and explore NAD+ and Sermorelin, MYRNK delivers something relatively rare in the telehealth space: multiple NAD+ delivery formats, personal coaching, and GLP-1 availability for those who want to combine both. That said, the recurring shipping and dosage-related complaints in patient reviews mean it’s worth going in with clear expectations, careful attention to the refund policy, and questions ready for your clinician about cold-chain handling.

As with any subscription platform, we strongly recommend reviewing all pricing, refund, and cancellation terms before enrolling.
