Side-by-side comparison of key properties, dosing, and research.

Sermorelin
Summary
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that declines dramatically with age. It is critical for energy metabolism, DNA repair, and sirtuin activation. IV and subcutaneous NAD+ supplementation is used in anti-aging protocols and addiction recovery programs.
Sermorelin is a bioidentical synthetic peptide comprising the first 29 amino acids of naturally occurring GHRH. It is FDA-approved for diagnostic use and widely prescribed off-label for anti-aging, stimulating growth hormone production in a natural pulsatile pattern that mimics the body's own rhythm.

Key Benefits
  • Restored cellular energy production (ATP)
  • Sirtuin activation for longevity and metabolic regulation
  • Enhanced DNA repair capacity
  • Improved mitochondrial function and biogenesis
  • Cognitive clarity and mental energy
  • Reduced inflammation
  • Addiction withdrawal support (opioids, alcohol, benzodiazepines)
  • Improved sleep quality
  • Enhanced athletic endurance
  • Increases energy and vitality
  • Improves body composition (more muscle, less fat)
  • Enhances skin thickness and elasticity
  • Strengthens immune system
  • Improves sleep quality and REM sleep
  • Supports bone density
  • Enhances mental clarity and focus
  • Safer than exogenous HGH — respects natural feedback loops
  • FDA-approved for GH diagnostic use
Side Effects
