Epitalon reconstitution calculator
Type in a vial size, the diluent volume you added, and a dose figure — the calculator below converts those three numbers into a concentration, a draw volume, and a syringe reading. It performs the same arithmetic as our tirzepatide and sermorelin calculators. What it cannot do, for epitalon specifically, is check that arithmetic against an FDA-approved product's own label, because no such label — or product — exists. Read why below before you use it.
There is no approved product or dosing standard behind this calculator
Epitalon — sometimes spelled "Epithalon" — is a synthetic four-amino-acid peptide (Ala-Glu-Asp-Gly) modeled on epithalamin, a natural pineal-gland peptide preparation studied in Russian aging research since the late 20th century. It is chemically and clinically distinct from the other peptides on this calculator: its research base centers on telomerase activation, pineal/circadian function and sleep, and longevity biology, drawn mostly from animal studies and a limited, dated body of Russian human research that has not been replicated in FDA-standard trials. It has never had an FDA-approved drug product of its own: a direct check against DailyMed, the National Library of Medicine's official archive of FDA-approved drug labeling, returns zero results for both "epitalon" and "epithalon."
Its compounding status is unsettled, and moved recently: at FDA's Pharmacy Compounding Advisory Committee meeting on July 23-24, 2026, epitalon was one of seven peptides formally reviewed for inclusion on the 503A bulks list — reviewed on the second day, alongside Semax and Emideltide/DSIP. The committee voted 7-4-1 recommending epitalon be added, for its nominated insomnia indication — a closer vote than a simple majority might suggest, and notably not every peptide reviewed that week fared the same: Emideltide/DSIP, reviewed the same day, failed to get a majority recommendation at all (6-7-1). FDA has published no minutes or vote record for that meeting; the tally comes from law-firm accounts of the public session. A committee recommendation is not final agency action — as of this page's last review, FDA had not yet formally added epitalon to the list.
What the tool below actually does is narrower than that context might suggest: it takes the vial size, diluent volume, and dose you type in and returns the concentration and draw volume that arithmetic implies — nothing more. It cannot confirm that a particular vial is what its label claims, that the dose you enter is appropriate for you, that it is currently legal for a pharmacy to have compounded it, or that the product you drew that number from came from a legitimate source. A correct-looking syringe reading is not evidence that any of those things are true.
