NAD+
Sirtuin activation (SIRT1/SIRT3); PARP-1 DNA repair; mitochondrial biogenesis via PGC-1α
GHK-Cu
Collagen synthesis; antioxidant gene upregulation (SOD, catalase); DNA repair via FOXO3a
Clinical Decision Framework
When evaluating NAD+ versus GHK-Cu for biological age reduction, the primary consideration is the specific hallmark of aging being targeted. While both compounds offer systemic healthspan benefits, their mechanisms of action are distinct.
When to prioritize NAD+:
Select NAD+ when the primary clinical objective aligns with its core mechanism: coenzyme that fuels sirtuins and parp enzymes for dna repair, mitochondrial biogenesis, and energy metabolism.. This is particularly relevant for protocols focused on cellular energy restoration, dna repair activation, and anti-aging pathway stimulation..
When to prioritize GHK-Cu:
Conversely, GHK-Cu is the superior choice when targeting copper-binding tripeptide that activates over 4,000 genes involved in collagen synthesis, antioxidant defense, and tissue remodeling., making it the preferred agent for skin regeneration, collagen synthesis, and systemic anti-aging gene activation..
