I’m a longevity doctor — 3 peptides that can help you live longer

Epitalon
Another hallmark of aging? Shortened telomeres.

“As the cells divide, your telomeres — the end caps of chromosomes — get shorter and shorter,” Aziz explained. “And eventually there is no more cell division, and there’s cell death. So longer telomeres mean longer life. Shorter telomeres means shorter life.”

GHK-Cu
Though the research on the longevity properties of this peptide are insufficient, existing research suggests that GHK-Cu — a property found in human saliva, urine and plasma and combined with a copper compound — can build collagen and facilitate DNA repair via injection, helping to recoup the stem cells we lose as we age.

“We have about 700,000 stem cells in our body when we’re born, and they go down as we age,” Aziz said. “By age 60, they’re all gone. And it’s believed that GHK-Cu helps keep the stem cells alive longer.”
