Prata et al., 2018)

This inhibition preserves cellular NAD+ levels by reducing their consumption, simultaneously increasing GLUT4 transporter expression and activating sirtuin 1, known as the "longevity gene." The compound exhibits high membrane permeability and selectivity without affecting related methyltransferases or NAD+ salvage pathway enzymes, creating targeted metabolic effects while maintaining cellular safety

This is because GHK-Cu itself works in picogram quantities

Sleep peptides Sleepsupporting peptides include Delta SleepInducing Peptide (DSIP), growthhormone secretagogues (CJC1295, Ipamorelin), Epitalon, and adjunctive peptides such as BPC157, which reduce inflammation and thus indirectly improve sleep continuity
