A longevity doctor highlights three peptides, semaglutide, epitalon, and GHK-Cu, that may support healthier aging, while warning that benefits are still being studied and medical supervision is essential.

A growing wave of anti-aging research is focusing on peptides, small chains of amino acids that act as signaling molecules in the body, as scientists and “biohackers” search for ways to extend healthy lifespan.
According to longevity specialist Michael Aziz, author of The Ageless Revolution, certain peptides may improve metabolic health, protect cells, and slow aging processes when used responsibly under medical supervision.
He highlighted three compounds gaining attention.
1. Semaglutide
Best known through diabetes and weight-loss drugs like Ozempic and Wegovy, semaglutide is his top longevity pick.
Originally developed to control blood sugar, research suggests it may also reduce the risk of heart attack and stroke by around 20% by improving metabolic function.
Aziz says some doctors are now considering low “maintenance doses” for patients with prediabetes or high cardiovascular risk, not for weight loss but long-term metabolic protection.
However, other physicians caution that lifestyle changes should come first because GLP-1 medications can cause side effects ranging from nausea and dizziness to rare complications such as pancreatitis.
2. Epitalon
Epitalon targets aging at the cellular level by acting on telomeres, protective caps at the ends of chromosomes that shorten as cells divide.
Preliminary laboratory studies suggest it may lengthen telomeres and delay cell aging. Aziz says potential benefits could include improved sleep, antioxidant effects, and reduced risk of age-related diseases, though human research remains limited.
Experts emphasize that it is not widely approved for routine medical use and requires far more clinical testing.
3. GHK-Cu
This copper-binding peptide occurs naturally in human fluids and is already popular in skincare products.
Early research suggests it may stimulate collagen production, support DNA repair, and help preserve stem cells as people age. It is commonly applied topically, though injectable forms exist.
For now, scientists say its strongest evidence remains cosmetic rather than medical.
Safety concerns and “gray market” risks
Aziz warns that many peptides, especially those not formally approved, are being purchased online from unregulated sellers. Prices can range from about $1,000 per month for brand-name GLP-1 drugs to far cheaper unofficial versions sold on social media platforms.
“Patients should work with a medical professional,” he said, noting counterfeit or contaminated compounds can be dangerous.
Researchers stress that peptides are not a miracle cure for aging. Diet, exercise, and sleep remain the foundation of longevity, with peptide therapies still an emerging field requiring more human studies.
