NAD+ (nicotinamide adenine dinucleotide) is a 6-Week peptide therapeutic cycle delivered through a convenient “Selfie” Variable, Multi Dose Pen. NAD+ is a vital coenzyme found in all living cells, central to energy production and cellular health. It alternates between oxidized (NAD+) and reduced (NADH) forms to drive over 500 enzymatic reactions that sustain life. Beyond metabolism, NAD+ supports DNA repair, gene regulation, and protects against aging by powering enzymes like sirtuins and PARPs, which regulate cellular function and maintain genomic stability. Research suggests NAD+ may enhance muscle performance, protect nerve cells, and slow age-related decline.
