Science-backed support for cellular health.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell that is essential for converting nutrients into cellular energy and supporting DNA repair. NAD+ levels decline measurably with age, by roughly 50% between ages 40 and 60, and can be further depleted by chronic stress, poor sleep, and alcohol consumption. Without adequate NAD+, mitochondrial function slows, cellular repair processes become less efficient, and energy metabolism declines.

NAD+ is available as a nasal spray through Surfbound. Your provider will recommend the strength — including 900 mg or 1,200 mg — that best fits your health profile and goals.

NAD+ therapy may support cellular energy production, cognitive function, and metabolic health by replenishing declining coenzyme levels. People explore NAD+ — delivered as a nasal spray — for improved energy, mental clarity, exercise recovery, and support for healthy aging at the cellular level. Because NAD+ is fundamental to mitochondrial function and DNA repair, restoring levels may help offset some of the metabolic changes associated with aging.

Sermorelin is a synthetic peptide analog of growth hormone-releasing hormone (GHRH) that signals the pituitary gland to produce and release your own growth hormone in natural, pulsatile patterns. This is the key distinction from direct HGH injections: Sermorelin works upstream, prompting your body to make its own growth hormone rather than introducing exogenous hormone. Because the pituitary retains its natural feedback mechanisms, growth hormone output stays within physiological ranges. The body self-regulates.

Sermorelin may support lean body composition, bone density, sleep quality, and recovery by encouraging the body’s own growth hormone production in natural circadian pulses. Because it preserves the pituitary’s natural feedback loops, growth hormone levels stay within physiological ranges. People typically explore Sermorelin for body composition goals, improved recovery from exercise, deeper sleep, and supporting age-related changes in growth hormone secretion.

Longevity treatments through Surfbound are typically intended for adults experiencing age-related changes in energy, body composition, recovery, or overall cellular health. A licensed provider reviews your health profile, including medical history, current medications, and goals, to determine whether NAD+ or Sermorelin is medically appropriate. Lab work may be required for certain treatments (particularly Sermorelin). These treatments are not for everyone; the provider makes the clinical determination after review.

It depends on the treatment. For Sermorelin, providers typically require blood work, including IGF-1 levels, a comprehensive metabolic panel (CMP), and a complete blood count (CBC), to make an informed prescribing decision. For NAD+, lab work may be requested based on your individual health profile and history. Your provider will let you know exactly what is needed after reviewing your online intake.

Compounded medications, including NAD+ and Sermorelin, are not FDA-approved finished drug products. They are prepared by licensed compounding pharmacies for individual patients when a provider determines treatment is medically appropriate. Compounded drugs do not undergo the same FDA premarket review for safety and efficacy as brand-name medications. For context on Sermorelin specifically: the original FDA-approved brand (Geref) was voluntarily withdrawn by its manufacturer in 2008 for business reasons, not safety or efficacy, which is why compounding pharmacies are permitted to prepare it today.

They target different systems. NAD+ supports cellular energy and DNA repair at the mitochondrial level. Sermorelin works through the pituitary to encourage natural growth hormone production, affecting body composition, recovery, and sleep. They are complementary rather than competitive — some people use both. Your provider determines which, if any, is appropriate based on your health profile and goals.
