Longevity medicine, explained by clinicians
Clear, physician-reviewed answers to the questions people actually ask about NAD+, sermorelin, and at-home longevity care. No hype, just how it works and what the evidence does and doesn't say.
What is NAD+?
The coenzyme behind cellular energy and DNA repair: what it is, why levels fall with age, and how physician-directed NAD+ therapy is delivered.
Read NAD+ · ComparisonNAD+ injections vs. IV drips
At-home subcutaneous shots or an in-clinic intravenous drip? A clear comparison of cost, convenience, and continuity of care.
Read NAD+ · How-toHow to do NAD+ injections at home
A small subcutaneous shot you give yourself after a physician's instruction. Here is what the routine actually looks like.
Read NAD+ · ComparisonNAD+ vs. NMN vs. NR
Injectable NAD+ or oral NMN and NR supplements? The honest difference is oversight and quality control, not a winner.
Read NAD+ · CostHow much does NAD+ therapy cost?
A transparent breakdown of at-home subcutaneous NAD+ at $299 per month versus in-clinic per-session pricing, and what drives the difference.
Read NAD+ · SafetyNAD+ injection side effects
NAD+ injections are generally well tolerated when physician-monitored. Here are the common, mild effects and when to check in.
Read NAD+ · DosingNAD+ dosage, explained
There is no universal NAD+ dose. It is individualized and physician-directed, typically started low and titrated to your response.
Read NAD+ · BenefitsNAD+ for energy
How NAD+ relates to cellular energy metabolism, what the early evidence shows, and the physician-directed path. Individual results vary.
Read NAD+ · Get StartedHow to get NAD+ prescribed online
The legitimate, physician-directed path: a four-step telehealth process from a LegitScript-certified practice.
Read NAD+ · BenefitsNAD+ for brain fog
How NAD+ relates to cellular energy, what the early evidence shows about mental clarity, and when to see a physician.
Read Trust & SafetyIs telehealth longevity medicine legitimate?
Yes, when it's physician-directed, certified, and transparent. Here's exactly how to tell a credible clinic from a prescription mill.
Read Sermorelin · BasicsWhat is sermorelin?
A growth hormone-releasing hormone analog that signals your own pituitary rather than replacing the hormone. What it is, what it is not, and what the published evidence actually shows.
Read Sermorelin · How it worksSermorelin injections at home
What a subcutaneous injection actually involves, why the timing follows sleep, and why at-home is a location rather than a level of supervision.
Read Sermorelin · SafetySermorelin side effects
What the published human studies actually report, what a prescribing physician screens for, and which reactions mean call us rather than wait.
Read Sermorelin · ProtocolSermorelin dosage
Why a dosing chart is the wrong artifact, what the published protocols used, and how baseline IGF-1 turns a dose into a decision rather than a guess.
Read Sermorelin · PricingHow much does sermorelin cost?
The published price, what it covers, why the lab panel is billed separately, and why a per-vial number found elsewhere is not the same purchase.
Read Sermorelin · Getting startedHow to get sermorelin prescribed online
Four steps, and the third one decides whether there is a fourth. What a clinical process looks like when the lab step is allowed to end it.
Read Sermorelin · EvidenceSermorelin for sleep and recovery
A well-described physiological link and a thin outcome literature are two different claims. Which one the evidence supports, and what to rule out first if sleep is the real problem.
Read Longevity Stack · Cross-productNAD+ and sermorelin together
Two separately studied pathways in one program. What each is supported by on its own, and why the combination is a rationale rather than a result.
Read Sermorelin · MechanismWhat is growth hormone-releasing hormone (GHRH)?
The upstream signal, not the hormone. Where GHRH is made, how it reaches the pituitary, why growth hormone comes out in pulses, and what the measured age-related decline actually is.
Read Labs · ProtocolLab work and peptide therapy
Why the baseline panel is a prerequisite rather than an upsell, why IGF-1 is the marker, and what it means that a result is allowed to end the conversation.
Read Trust · How care is deliveredPhysician-directed versus direct-to-consumer
The difference is not the website. It is whether the process contains a step that is allowed to end in no therapy. Three questions, and what the research says about why they matter.
Read Trust · Vetting a providerIs online sermorelin legitimate?
A sermorelin-specific version of the vetting checklist: what to verify before you pay, and the one question whose answer separates a clinical process from a fulfilment pipeline.
