What is the difference between Endoluten and Epithalon?

Endoluten: Pineal-targeted peptide complex that modulates melatonin synthesis pathways and circadian gene expression. May help restore age-related decline in pineal activity and improve circadian rhythm regulation. Epithalon: Epithalon is believed to activate telomerase, the enzyme responsible for maintaining telomere length, with several in vitro and animal studies reporting telomere elongation.

Is Epithalon FDA approved?

Epithalon is the subject of a favorable FDA advisory committee vote but not FDA approved, and its legal status for compounding is unchanged. It is discussed for research and educational purposes only, not as medical guidance.

How is Endoluten administered in research settings?

In research settings, Endoluten is typically administered via the oral or subcutaneous routes. PeptideBase does not provide dosing or administration instructions.

How is Epithalon administered in research settings?

In research settings, Epithalon is typically administered via the subcutaneous or intravenous routes. PeptideBase does not provide dosing or administration instructions.

About Endoluten

Pineal-targeted peptide complex that modulates melatonin synthesis pathways and circadian gene expression. May help restore age-related decline in pineal activity and improve circadian rhythm regulation.

Research Areas

About Epithalon

Epithalon is believed to activate telomerase, the enzyme responsible for maintaining telomere length, with several in vitro and animal studies reporting telomere elongation. It also appears to regulate the expression of p53 and other cell-cycle control genes, modulate the hypothalamic-pituitary axis via pineal gland activity, and upregulate antioxidant defences including superoxide dismutase and catalase.

Safety Profile

Information below reflects published research data only — not medical advice. Consult a qualified provider before use.

Endoluten

No established clinical contraindications. This is an investigational compound with limited human data and has not been evaluated by the FDA for safety in this context. Consult a qualified clinician.

Used Together?

Epithalon

GHK-Cu
Research suggests Epithalon and GHK-Cu may produce complementary longevity-associated effects when combined. Epithalon is studied for telomere maintenance and pineal function, while GHK-Cu is studied for antioxidant gene expression and tissue remodeling — different mechanisms in aging research.
