This week's "Skin Renewal Guide" will discuss peptides. I currently receive NAD peptide and copper peptide injections five days a week. What are your thoughts on NAD peptides and peptides in general? Feel free to leave a comment below. Benefits of NAD peptide injections: Anti-aging, slows down cell aging, improves brain function, accelerates recovery, promotes metabolism, and boosts energy. Benefits of copper peptide injections: Promotes collagen and elastin production, accelerates skin repair, reduces inflammation, improves skin texture and smoothness, provides antioxidant benefits, evens skin tone, and strengthens the skin barrier. I inject for three months, then stop for three months, and then start injecting again.
