They help maintain energy production, membrane integrity, antioxidant protection, neurotransmitter communication, and gene regulation

The research reveals that GHK-Cu modulates the NAD-dependent deacetylase sirtuin-1 (SIRT1) and the signal transducer and activator of transcription 3 (STAT3) signaling pathway

When your mitochondria produce energy (using NAD+), they naturally create some oxidative stress as a byproduct
