NAD+ (nicotinamide adenine dinucleotide) is a coenzyme essential for cellular energy production and DNA repair. NAD+ levels decline with age. Physician-supervised NAD+ therapy may support energy metabolism, mitochondrial function, and cellular repair. Peptide therapies including Sermorelin may support growth hormone secretion and recovery. All require physician evaluation and prescription.
The conversation around men's health has shifted. A growing cohort of men — particularly those in their 40s, 50s, and beyond — are no longer satisfied with "normal for your age." They want to perform at the level they did at 30. They want to recover faster, think more clearly, and maintain the physical capacity they've built over decades.
Longevity medicine — the physician-supervised use of compounds that support cellular health, mitochondrial function, and hormonal optimization — has moved from fringe biohacking to mainstream clinical practice. NAD+ therapy and peptide protocols are at the center of this shift.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of the body. It is essential for:
NAD+ levels decline significantly with age — by approximately 50% between the ages of 40 and 60. This decline is associated with reduced energy, slower recovery, cognitive decline, and increased susceptibility to age-related disease.
Physician-prescribed NAD+ therapy is available in multiple forms:
| Form | Administration | Onset | Notes |
| IV Infusion | Intravenous (clinic) | Immediate | Highest bioavailability; requires clinic visit |
| Subcutaneous Injection | Self-injected | Fast | High bioavailability; at-home administration |
| Nasal Spray | Intranasal | Moderate | Convenient; good CNS delivery |
| Oral Tablet (Flex Tablet) | Daily oral | Slower | Most convenient; lower bioavailability |
Redline RX provides physician-prescribed NAD+ via subcutaneous injection, nasal spray, and oral tablet — all available for at-home administration and shipped monthly.
Sermorelin is a growth hormone-releasing hormone (GHRH) analogue — a peptide that stimulates the pituitary gland to produce and release growth hormone (GH) naturally. Unlike synthetic HGH, Sermorelin works through the body's own regulatory mechanisms, making it a safer and more physiologically appropriate option for most men.
Growth hormone supports muscle protein synthesis, fat metabolism, bone density, sleep quality, and recovery. GH levels decline with age, contributing to the body composition changes many men experience after 40.
Sermorelin is available as a subcutaneous injection or orally dissolving tablet, physician-prescribed and shipped monthly.
For men seeking comprehensive optimization, Redline RX physicians build individualized longevity protocols that may include:
| Compound | Primary Benefit | Form |
| NAD+ | Cellular energy, DNA repair | Injection / nasal spray / oral |
| Sermorelin | GH stimulation, recovery, body composition | Injection / ODT |
| Glutathione | Antioxidant, detoxification, immune support | Injection |
| MIC B12 | Fat metabolism, energy, neurological support | Injection |
| Methylene Blue | Mitochondrial support, cognitive function | Oral |
| GHK-Cu | Tissue repair, collagen synthesis, anti-inflammatory | Topical / injection |
| Lipo-C | Fat mobilization, liver support | Injection |
Each protocol is individualized based on labs, symptoms, age, and goals. No two protocols are identical.
Men over 40 who are already optimizing their testosterone and sexual health often find that longevity protocols provide the additional layer of performance they're looking for. Specific candidates include:
All Redline RX longevity protocols are physician-prescribed and monitored. Peptide therapies are generally well-tolerated with minimal side effects under proper physician supervision. NAD+ therapy may cause transient flushing or nausea at higher doses — typically managed by dose adjustment.
Physician evaluation is required before initiating any longevity protocol. Results may vary.
