Where it shows up in research

literature areas · not a health claim
Pineal-peptide and circadian-biology research (animal studies)Telomere and cellular-aging research (cell and animal studies)Antioxidant and gene-expression research (preclinical)

These are areas explored in the scientific literature, largely in cell and animal studies; they are not health claims and do not indicate any effect in people.

Storage & handling

Planning a reconstitution? Use the calculator — it is math for handling a vial, not dosing.

Looking at this for yourself? Epithalon is a research compound — whether it is right for a person is a medical question we cannot answer. Talk to a licensed clinician. Everything on this page is for laboratory research use only.

Frequently asked

How much does Epithalon cost?
About $33–$67 per vial, depending on vial size. Compare the same size across vendors.
Why do Epithalon prices vary so much?
Vial sizes differ, so always compare the same vial size across vendors. Batch testing, stock, and pack discounts move the true cost too — see what "Verified" means.
How are Epithalon vendors verified?
A vendor earns a Verified badge only after independent batch testing (HPLC purity + mass-spec identity) checks out against its COA. Verification is never for sale.
