Epithalon

Epithalon, also written Epitalon or referred to as the AEDG peptide in the literature, is a synthetic tetrapeptide studied for its potential role in cellular longevity and biological-rhythm pathways. Research has focused on its relationship with telomere biology and pineal signaling, and recent reviews describe it as a highly bioactive pineal tetrapeptide. It is categorized as a longevity research compound and is supplied for laboratory research use only.

Research investigates two main pathways. The first is telomere biology: Epithalon has been studied for a possible influence on telomerase activity, which is tied to maintaining chromosomal end-caps during cell division. The second is circadian regulation, where it has been explored in research on pineal signaling and the systems coordinating rest, hormone release, and daily rhythm. A cell study has also proposed a possible epigenetic mechanism affecting gene expression.

A 2025 cell study reported increased telomere length in human cell lines through telomerase upregulation or alternative lengthening of telomeres activity. Other work has examined gene expression and protein synthesis during neurogenesis, delayed wound healing in an in vitro model of diabetic retinopathy, and protection against post-ovulatory aging-related damage in mouse oocytes. These findings come from laboratory and animal models, and their relevance to humans has not been established.

Human safety data for Epithalon are limited. The available literature is dominated by cell-culture and animal studies, and adverse events are not summarized in the cited studies. Long-term effects have not been characterized in controlled human trials. Because evidence is largely preclinical, conclusions about safety or tolerability in people cannot be drawn from the current body of research, and findings should be interpreted conservatively.

Research protocols have used 2 to 10 mg per administration, once daily before sleep, by the subcutaneous route. The reported cycle is 20 consecutive days followed by a break, repeated up to three times per year at roughly four-month intervals. These figures describe published research protocols only and are not recommendations. Each CoreX order ships with a protocol guide for laboratory reference.
