NAD+ therapy has emerged as one of the mostpromising interventions in longevity medicine. But once you’ve decided topursue NAD+ therapy, a practical question arises: how should you take it?
Luvo’s longevity program is one of the fewthat offers three distinct NAD+ delivery options — injection, oral liquiddrops, and nasal spray. Each method has different absorption characteristics,convenience factors, and potential advantages. This guide helps you understandthe differences so you can make an informed choice with your Luvo provider.
NAD+ injection delivers the molecule directlyinto your body via subcutaneous or intramuscular injection, bypassing thedigestive system entirely.
Bioavailability is the standout advantage.Because the NAD+ enters your system without passing through the GI tract orliver first-pass metabolism, a much higher percentage of the administered dosereaches your cells. This makes injection the most efficient delivery method interms of dose-to-effect ratio.
Injections are typically administered on a setschedule — often 2-3 times per week depending on your protocol. Many patientsreport the most pronounced and rapid effects with injectable NAD+, includingnoticeable energy improvements and mental clarity within the first week.
The trade-off is that injections requirecomfort with self-administration (though the needles are very small) and properstorage of the medication. For patients who want the highest-impact NAD+delivery and don’t mind the injection process, this is often the preferredchoice.

NAD+ oral liquid drops are designed forsublingual administration — placed under the tongue and held for 30-60 secondsbefore swallowing. This route allows a portion of the NAD+ to absorb directlythrough the mucous membranes of the mouth into the bloodstream.
Sublingual absorption partially bypassesdigestive degradation, offering better bioavailability than standard oralcapsules or tablets. The liquid formulation is also easier to dose preciselyand absorb than solid supplements.
The primary advantage is convenience and easeof use. There are no needles, no special storage requirements beyond basicguidelines, and the drops can be taken anywhere as part of a daily routine.This makes oral drops particularly appealing for patients who are new to NAD+therapy or prefer a gentler introduction.
Bioavailability is moderate compared toinjection — some NAD+ is still lost to digestive processes. However, consistentdaily dosing can build and maintain meaningful NAD+ levels over time.

NAD+ nasal spray delivers the molecule throughthe nasal mucosa — the thin, highly vascularized tissue lining the nasalpassages. This route offers rapid absorption into the bloodstream and a uniquepotential advantage: proximity to the brain.
The nasal cavity is separated from the brainby the cribriform plate, a thin bony structure that allows some moleculesdelivered intranasally to reach the central nervous system more directly thanother delivery routes. While research on intranasal NAD+ specifically is stilldeveloping, the theoretical advantage for cognitive benefits — includingimproved focus, mental clarity, and neuroprotection — makes this an excitingoption for patients whose primary concern is brain health.
Nasal spray is also needle-free and quick toadminister, making it a practical choice for daily use. Most patients find itstraightforward after the first few uses.
The bioavailability of nasal delivery fallsbetween injection and oral drops, offering a solid middle ground for patientswho want better absorption than oral but prefer to avoid injections.

The right choice depends on your priorities.
If maximum potency and fastest results areyour priority, NAD+ injection is the clear leader. It delivers the most NAD+per dose and produces the most pronounced effects. Choose this if you’recomfortable with needles and want the strongest intervention.
If convenience and simplicity matter most,NAD+ oral liquid drops fit seamlessly into any daily routine. They’re theeasiest to start with and require no special technique. Choose this if you wanta low-friction daily habit.
If cognitive function and brain health areyour focus, NAD+ nasal spray offers a compelling combination of ease andpotential neuro-specific benefits. Choose this if mental clarity, focus, andbrain longevity are top priorities.
If you want comprehensive coverage, somepatients in Luvo’s longevity program use a combination of delivery methods —for example, injections twice weekly supplemented by daily nasal spray. Yourprovider can help design a protocol that maximizes benefit for your specificgoals.

Starting around age 30, your body’s productionof growth hormone begins a steady decline — roughly 14% per decade. By the timeyou’re 60, you may be producing a fraction of the growth hormone you made inyour twenties. This isn’t a disease. It’s a natural part of aging. But theconsequences are far-reaching.
Growth hormone isn’t just about growth. Inadults, it plays critical roles in maintaining muscle mass, regulating body fatdistribution, supporting bone density, enabling tissue repair, and sustainingenergy and recovery. When levels decline, you experience what many peoplesimply accept as “getting old” — increased belly fat, muscle wasting, slowerrecovery, poor sleep, and declining vitality.
Sermorelin offers a way to address thisdecline naturally, and it’s a cornerstone of Luvo’s longevity program.
Sermorelin is a growth hormone-releasinghormone (GHRH) analog — a synthetic version of the first 29 amino acids of thenaturally occurring GHRH your hypothalamus produces. When administered, itstimulates your pituitary gland to release more of its own growth hormone.
This mechanism is fundamentally different fromsynthetic human growth hormone (HGH) injections, which introduce externalgrowth hormone directly into your body. With Sermorelin, you’re not replacingyour natural growth hormone — you’re reactivating your body’s own productionsystem.
This distinction matters for several reasons.Sermorelin preserves the natural pulsatile pattern of growth hormone release,which is how the body is designed to use it. It works with your body’s feedbackloops rather than overriding them, reducing the risk of excess. And because thepituitary maintains control, the risk of supraphysiological (above-normal)growth hormone levels is significantly lower than with direct HGH injection.
Synthetic HGH therapy has been available fordecades, but it carries significant concerns that make it poorly suited forlongevity use. Direct HGH injection bypasses the body’s regulatory mechanisms.This can lead to side effects including joint pain, carpal tunnel syndrome,insulin resistance, and potential concerns about accelerated growth of abnormalcells.
HGH also has regulatory and legal complexity.It’s a controlled substance with strict prescribing criteria, and its use for“anti-aging” purposes exists in a legal gray area.
Sermorelin avoids these issues. Because itworks through your pituitary gland, growth hormone release is self-regulated —your body produces what it needs, not an arbitrary external amount. Sideeffects are generally mild and uncommon. And Sermorelin is legally prescribedfor growth hormone optimization without the regulatory concerns of HGH.
Competitors like Remedy Meds and OrderlyMedsmay offer basic peptide access, but Luvo’s program integrates Sermorelin into acomprehensive longevity protocol with clinical oversight, dosing optimization,and complementary therapies like NAD+ and B12/MIC.
The clinical and patient-reported benefits ofSermorelin therapy address many of the most frustrating aspects of aging.
Improved body composition is one of the mostnoticeable effects. Growth hormone plays a direct role in fat metabolism andmuscle maintenance. Patients on Sermorelin commonly report reduced abdominalfat and improved muscle tone, even without dramatic changes to their exerciseroutine.
Better sleep quality is another significantbenefit. Growth hormone is primarily released during deep sleep, and Sermorelinhelps restore this natural pattern. Many patients report falling asleep faster,sleeping more deeply, and waking more refreshed — improvements that cascadeinto every area of health.
Enhanced recovery shows up as faster healingfrom workouts, injuries, and the general wear-and-tear of daily life. Growthhormone is essential for tissue repair, and restoring healthy levels supportsthis process.
Stronger immune function, improved skinelasticity, and better cognitive clarity are also commonly reported, thoughindividual results vary based on baseline growth hormone levels and overallhealth.
Sermorelin is administered via subcutaneousinjection, typically in the evening to align with the body’s natural growth hormonerelease cycle during sleep. Most patients adapt to the injection processquickly — the needle is small and the injection is virtually painless.
Results develop gradually. Most patientsnotice improvements in sleep quality and energy within the first 2-4 weeks.Body composition changes and recovery improvements typically become apparentover 2-3 months. The full benefits of Sermorelin therapy continue to developover 3-6 months of consistent use.
Your Luvo provider will establish yourstarting dose based on your health profile and goals, then monitor yourprogress with regular check-ins. Dose adjustments are made based on yourclinical response and, when indicated, lab work to track growth hormone andIGF-1 levels.

The longevity conversation has exploded inrecent years. Podcasts, bestselling books, and a growing community ofresearchers and biohackers have brought the science of aging into mainstreamawareness. But beneath the hype, there’s a serious and rapidly evolving medicaldiscipline focused on one central question: how do we extend not just lifespan,but healthspan — the number of years you live in good health, free from chronicdisease and functional decline?
That’s the foundation of Luvo’s longevityprogram. It’s not about miracle cures or reversing the clock. It’s about usingevidence-based therapies to support your body’s own repair and regenerationsystems as they naturally slow down with age.
The wellness industry is flooded with productspromising to “reverse aging.” Most of these claims are unsupported by clinicalevidence. Longevity medicine is fundamentally different. It’s a clinical disciplinerooted in the biology of aging — specifically, the molecular and cellularmechanisms that drive age-related decline.
Researchers have identified several hallmarksof aging: mitochondrial dysfunction, cellular senescence, epigenetic changes,loss of proteostasis, and declining levels of critical molecules like NAD+ andgrowth hormone. Longevity medicine targets these mechanisms directly, usingtherapies that have measurable biological effects — not just cosmetic ones.
Competitors in the telehealth space —companies like Hims and Pomegranate — tend to focus on single-symptomtreatments. Luvo’s longevity program takes a systems-level approach, combiningmultiple therapies that address different hallmarks of aging simultaneously.
Luvo’s longevity program is built around fivemedications, each targeting a different aspect of age-related decline.
Sermorelin is a growth hormone-releasingpeptide that stimulates your pituitary gland to produce more of its own growthhormone. Growth hormone levels decline significantly with age, contributing tomuscle loss, increased body fat, reduced bone density, and slower recovery.Sermorelin restores this signaling naturally.
NAD+ therapy is available in three deliveryformats — injection, oral liquid drops, and nasal spray. NAD+ (nicotinamideadenine dinucleotide) is a coenzyme essential for cellular energy production,DNA repair, and activation of sirtuins — the proteins that regulate aging atthe cellular level. NAD+ levels decline by as much as 50% between ages 40 and60.
Vitamin B12/MIC is a lipotropic injectioncombining Vitamin B12 with methionine, inositol, and choline. This combinationsupports energy metabolism, fat metabolism, liver function, and methylation — abiochemical process critical for DNA maintenance and detoxification.
Together, these therapies create acomprehensive protocol addressing energy production, hormonal optimization,cellular repair, and metabolic health.
Luvo’s longevity program is designed foradults who are proactive about their health — people who don’t want to waituntil disease develops to take action. You might be a good candidate if you’reexperiencing age-related fatigue, brain fog, or declining physical performance,if you’re interested in optimizing your healthspan based on the latest science,if you want clinical-grade therapies under medical supervision rather thanover-the-counter supplements of questionable quality, or if you’re looking fora comprehensive approach rather than a single-product solution.
The program is available through Luvo’stelehealth platform, with licensed providers who specialize in longevitymedicine and can tailor a protocol to your specific needs and goals.
Many competitors offer individuallongevity-adjacent products — an NAD+ supplement here, a B12 shot there. Whatsets Luvo apart is the integrated program design. Our providers don’t justprescribe a single therapy; they assess your overall health profile and build aprotocol that combines therapies for synergistic benefit.
Sermorelin supports the hormonal axis. NAD+fuels cellular repair. B12/MIC optimizes metabolic pathways. Together, theywork on multiple fronts — and that’s the kind of comprehensive approach thatlongevity science actually supports.

If you read most longevity articles, they focuson a single mechanism: take this one supplement, boost this one molecule, fixthis one pathway. But aging doesn’t work that way. It’s a convergence ofmultiple interconnected declines happening simultaneously — and addressing onlyone while ignoring the others produces limited results.
Three of the most well-documented andconsequential age-related declines are NAD+ depletion, growth hormonereduction, and methylation dysfunction. Individually, each drives significantaspects of aging. Together, they create a self-reinforcing cycle thataccelerates the entire process.
Luvo’s longevity program is specificallydesigned to address all three — and the science explains why this integratedapproach matters.
NAD+ sits at the center of cellular energymetabolism. As the essential coenzyme for mitochondrial ATP production, NAD+determines how efficiently your cells convert nutrients into usable energy.When NAD+ declines, mitochondria become dysfunctional — they produce less energyand more reactive oxygen species (free radicals), creating oxidative stressthat damages cellular components.
But NAD+’s role extends beyond energy. It’sthe required substrate for sirtuins, the family of proteins that regulate DNArepair, inflammation, and metabolic homeostasis. It’s consumed by PARP enzymesduring DNA repair. And it participates in over 500 enzymatic reactions thatmaintain cellular function.
The decline of NAD+ with age is a masterswitch that affects virtually every other cellular process. This is why NAD+therapy — whether through Luvo’s NAD+ injection, oral drops, or nasal spray —forms one pillar of the longevity program.
Growth hormone (GH) and its downstreammediator, IGF-1, are the body’s primary signals for tissue repair,regeneration, and maintenance. GH stimulates protein synthesis in muscles,collagen production in skin and connective tissue, bone mineralization, andimmune cell production.
The decline in GH production with age — termedsomatopause — directly contributes to muscle wasting (sarcopenia), increasedvisceral fat, reduced bone density, slower wound healing, and declining immunecompetence. These aren’t cosmetic issues; they’re functional declines thatpredict frailty, falls, metabolic disease, and reduced quality of life.
Sermorelin addresses somatopause by restoringthe pituitary’s natural GH output. But here’s the critical connection: growthhormone’s tissue-building effects require adequate cellular energy. Withoutsufficient NAD+ to power the metabolic machinery, the cells receiving GH’srepair signals may not have the energy to execute them. This is why Sermorelinand NAD+ therapy work better together than either does alone.
Methylation is a biochemical process where amethyl group (CH3) is transferred from one molecule to another. This seeminglysimple reaction is involved in DNA repair and gene expression regulation,neurotransmitter synthesis (serotonin, dopamine, melatonin), detoxification ofenvironmental toxins and metabolic waste, immune system regulation, andhistamine metabolism.
The methylation cycle requires adequate levelsof B12, folate, methionine, and choline — exactly the components in Luvo’sB12/MIC injection. When methylation declines with age or due to nutrientinsufficiency, the consequences cascade across multiple systems.
Perhaps most importantly, methylation is themechanism behind epigenetic regulation — the system that determines which genesare turned on or off. Disrupted methylation leads to aberrant gene expressionpatterns that are increasingly recognized as a hallmark of biological aging.Researchers now use DNA methylation patterns as “epigenetic clocks” to measurebiological age.
These three systems don’t operate inisolation. They’re deeply interconnected.
NAD+ fuels the sirtuins that regulateepigenetic patterns (methylation). Growth hormone stimulates tissue repair thatrequires NAD+-powered energy. Methylation recycles the precursors needed forboth NAD+ biosynthesis and growth hormone signaling. B12 and methionine supportthe salvage pathways that regenerate NAD+ from its metabolites.
When you address only one pillar, the othersbecome rate-limiting. Boosting NAD+ without supporting growth hormone leavesthe repair signals inadequate. Stimulating growth hormone without supportingcellular energy leaves cells unable to respond. Supporting methylation withoutadequate NAD+ limits the epigenetic maintenance that methylation is supposed toprovide.
This is the fundamental insight behind Luvo’smulti-therapy longevity program. Sermorelin, NAD+ therapy, and Vitamin B12/MICaren’t three random treatments bundled together — they’re three interventionstargeting the three pillars of cellular aging in a way that creates genuinesynergy.
