Epitalon vs Sermorelin
Both Epitalon and Sermorelin are used for anti-aging. Here's how their evidence, dosing, and regulatory status actually compare.
Epitalon
Evidence C+Epitalon (Epithalon, AEDG)
A synthetic tetrapeptide that reportedly upregulates telomerase activity. Russian longevity studies suggest mortality reductions but Western RCTs are absent.

Evidence B+Sermorelin Acetate (GHRH 1-29)
The original synthetic GHRH(1–29) and the most accessible GH-stimulating peptide for age-related hormone decline. Stimulates the body's own pulsatile GH release rather than replacing it.
