What peptides are commonly combined for anti-aging purposes?

GHK-Cu and Epithalon are two peptides frequently studied in anti-aging research. GHK-Cu is a naturally occurring copper peptide that declines with age and has demonstrated effects on collagen synthesis, wound healing, and antioxidant activity in studies. Epithalon is a tetrapeptide researched for its potential to upregulate telomerase activity, which helps maintain telomere length associated with cellular longevity. Clinical guidance generally recommends limiting peptide stacks to two or three compounds at once with proper monitoring.
