Age-Related Decline: Slow It Down and Take Years Back
Age-related decline is the cumulative effect of falling NAD+ (cellular energy), growth hormone (tissue repair), and other key molecules. NAD+ and sermorelin address the two most impactful age-related deficiencies, restoring the biological infrastructure that deteriorates after 30.
What it is
You used to bounce back from everything. Late nights, hard workouts, stressful weeks -- you recovered and kept going. Now each one takes a visible toll. The reserves you used to draw on are depleted, and each year they get a little shallower.
Age-related decline is not a single process -- it is the convergence of multiple biological systems losing capacity simultaneously. NAD+ drops 50% by age 40, reducing cellular energy production across every organ. Growth hormone drops 14% per decade, slowing tissue repair and body composition maintenance. Antioxidant defenses weaken. Inflammatory markers rise. The cumulative effect is what we experience as getting old.
The important insight is that these declines are individually addressable. You cannot stop time, but you can restore the specific molecules and hormonal signals that your body uses to maintain itself. The deterioration is not inevitable -- it is a set of deficiencies that modern medicine can correct.
Common causes
- •NAD+ decline -- 50% reduction by age 40, continuing to fall
- •Growth hormone decline -- 14% per decade after 30
- •Cumulative oxidative damage from decades of free radical exposure
- •Chronic low-grade inflammation (inflammaging) increasing with age
- •Mitochondrial dysfunction from accumulated DNA damage
- •Hormonal cascade effects -- each declining hormone affects others
Why typical solutions don't work
Anti-aging supplements target individual pathways without addressing the most impactful deficiencies. Taking 15 supplements that each move the needle 2% is less effective than restoring the two molecules (NAD+ and GH) that produce the largest functional improvements.
Lifestyle optimization is the foundation but has a ceiling. After 40, even perfect sleep, nutrition, and exercise cannot fully compensate for NAD+ and GH levels that have dropped below functional thresholds. Targeted restoration of these specific molecules breaks through the ceiling.
What clinical research shows
NAD+ supplementation increased blood levels 2.6-3.1x in a Lancet eClinicalMedicine trial, restoring cellular energy production to levels closer to youth. Sirtuins (longevity enzymes) depend on NAD+ and reactivate as levels rise, improving DNA repair, circadian regulation, and metabolic function.
Sermorelin restored IGF-1 to youthful levels within 14 days (Corpas et al., Journal of Clinical Endocrinology & Metabolism). Growth hormone drives tissue repair, muscle maintenance, fat metabolism, and deep sleep -- the systems that decline most noticeably with age. A 6-month study showed improved body composition and hormonal markers.

When you'll start feeling better
Week 1-2: Sleep quality improves (sermorelin). Energy begins rising (NAD+). These are the foundation.
Week 3-6: Cognitive clarity sharpens. Recovery from exercise and daily stress accelerates. Afternoon energy sustains.
Month 1-3: Body composition begins improving. Lean mass preserved or increasing, body fat decreasing. Skin quality improving.
Month 3-6: Full restoration of function. The compound effects of better energy, repair, and recovery produce a measurably different daily experience.
Month 6+: Sustained anti-aging benefit. Continued supplementation maintains the restored biological infrastructure against ongoing age-related decline.
Frequently asked questions
At what age should I start addressing age-related decline?
NAD+ decline begins in your 20s and becomes meaningful by 30-35. GH decline starts at 30. By 40, both are significantly depleted. The optimal time to start is when you first notice the effects -- declining energy, slower recovery, poor sleep quality, or body composition changes. Earlier intervention preserves more baseline function.
Why NAD+ and sermorelin specifically?
These address the two most impactful age-related deficiencies. NAD+ drives cellular energy production across every organ. GH (via sermorelin) drives tissue repair, muscle maintenance, and deep sleep. Together, they restore the biological infrastructure that all other body functions depend on.
Is this the same as hormone replacement therapy?
Sermorelin is not HRT in the traditional sense -- it stimulates your own pituitary to produce GH rather than injecting synthetic hormones. NAD+ is a coenzyme, not a hormone. Neither creates dependency or suppresses natural production. They restore levels that have declined below functional thresholds.
Will I feel like I'm 25 again?
The goal is to close the gap between your chronological age and your biological function. Most patients report feeling 10-15 years younger in terms of energy, recovery, sleep quality, and cognitive function. The improvement is meaningful and measurable, though it is restoration, not reversal to a specific age.
How long do I need to continue treatment?
NAD+ and GH continue declining with age. Maintaining restored levels requires ongoing supplementation. The benefits persist as long as treatment continues. If you stop, levels gradually return to their age-related baseline over weeks to months.
