Semaglutide vs Epithalon

Side-by-side comparison of key properties, dosing, and research.

GLP-1 / Weight Loss Agonists
Semaglutide
Anti-Aging & Longevity
Epithalon
Summary
Semaglutide is an FDA-approved GLP-1 receptor agonist originally developed for type 2 diabetes that has proven remarkably effective for weight loss. Clinical trials show average 15–20% body weight reduction. It is marketed as Ozempic (diabetes) and Wegovy (weight management).
Epithalon is a synthetic tetrapeptide developed from the pineal gland extract Epithalamin by Russian scientist Dr. Vladimir Khavinson. It is one of the most researched longevity peptides, known for activating telomerase and extending telomere length — the molecular hallmarks of cellular aging.
