nad+ and ghk cu together GHK-Cu Peptide NAD+ and GHK-Cu aren't interchangeable!

But since B12 is important for your overall health, you should prob up your intake anyway

It was also indicated that the fluorescence properties of Trp residues in the proteins can be described based on the existence of three discrete spectral classes, a buried in nonpolar regions of the protein ( max = 330332 nm, spectral band width = 4849 nm, quantum yield q = 0.11, and lifetime = 2.1 ns), a completely exposed to water ( max = 350353 nm, = 5961 nm, q = 0.2, = 5.4 ns)

NNMT (nicotinamide N-methyltransferase) is an enzyme that methylates nicotinamide, diverting it from NAD+ synthesis
