NAD+ vs Semax

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

Anti-Aging & Longevity
NAD+
Cognitive Enhancement
Semax
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.
Semax is a synthetic heptapeptide derived from ACTH developed in Russia. It is a potent nootropic that enhances memory, focus, and provides neuroprotection. Approved in Russia for cognitive disorders, stroke recovery, and traumatic brain injury.
Half-Life
Varies by route; IV provides direct cellular delivery
Minutes (but effects persist for hours via BDNF induction)
Admin Route
IV, SubQ, Oral
Intranasal, SubQ

  • Fast-acting — effects within 30–60 minutes
  • Approved in Russia for cognitive disorders and stroke recovery
Side Effects
  • Flushing and warmth during IV infusion
  • Nausea during rapid IV administration
  • Chest tightness (from rapid infusion — slow the rate)
  • Injection site irritation (subcutaneous)
  • +1 more
  • Headache (rare, often from higher doses)
  • Anxiety or overstimulation at high doses
