This page compares what is documented about Epithalon and Pinealon, rather than ranking them by effect. What each molecule is, the sizes and prices actually carried, what the certificate covers, and how the two differ on the bench. Everything here is research-use-only material and we do not publish outcome, dosing or administration content for any compound in the catalogue.
What is Epithalon and what is Pinealon?
Epithalon. Epithalon (AEDG) is the synthetic version of Khavinson's pineal tetrapeptide, studied in telomerase-activity and cellular-senescence models since the 1990s.
Pinealon. Pinealon is a tripeptide from the bioregulator family, studied in neurological research contexts.

At their best sizes Epithalon works out at $2.18 per mg against $4.25 for Pinealon — 95% more for the mg. Vial prices start at $40.00 and $60.00 respectively, which is the number most people compare and the one that says least, because the two are not sold in the same sizes. Full sizes, tier pricing and the lot certificate sit on the Epithalon page and the Pinealon page.
What is each one studied for?
What the published literature investigates, which is a different question from what either will do, and the only one of the two a supplier can answer.
Epithalon is studied in telomere-biology research. Telomere-biology research keeps the Khavinson peptides in circulation, with epithalon much the most-cited.
Pinealon is studied in peptide bioregulator research. Short peptide research continues to generate a steady publication stream, particularly outside English-language journals.
Studied in the same area does not make two compounds interchangeable, and the research library holds the per-compound documentation.
Pinealon vs Epithalon: how they differ on the bench
Pinealon. Tripeptides are among the most stable materials in the catalogue when dry and among the least stable once water is present.
Epithalon. AEDG's aspartate is prone to isomerisation in storage — the exact failure mode our epithalon stability guide walks through.
What actually differs between Pinealon and Epithalon
Worth doing the arithmetic before comparing sizes: Pinealon is 418.4 g/mol and Epithalon is 390.35 g/mol, a factor of 1.1. A milligram of Epithalon therefore contains roughly 1.1 times as many molecules as a milligram of Pinealon, so two vials of the same labelled mass hold quite different amounts of substance. Equal milligrams are not equal moles, which is what the molarity calculator exists to convert, and it is the reason a price-per-milligram comparison and a price-per-mole comparison can point at different vials.
Identity is the other analytical axis, and it is settled per lot rather than per compound. Epithalon. Catalogued as Epitalon, and the certificate's identity test resolves to that.
Both are released against a certificate reporting identity, purity by the stated method and net peptide content, readable before anything is bought.
Which is better, Pinealon or Epithalon?
Neither Pinealon nor Epithalon is ranked against the other here, and the refusal is deliberate. Better, safer and stronger are questions about effects in a living system, and we sell neither compound for use in one — why none of these pages ranks two compounds sets out the reasoning in full.
What it does instead, for these two:
- Epithalon is the cheaper of the two per mg, at $2.18 against $4.25.
- Pinealon is the heavier molecule by a factor of 1.1, so equal milligrams are not equal moles.
- Both are carried in 2 sizes, and each lot carries its own certificate.
Every one of those is checkable before you buy.
Common questions
What is the difference between Pinealon and Epithalon?
Different molecules before anything else: Pinealon is C15H26N6O8 and Epithalon is C14H22N4O9. Pinealon is a tripeptide from the bioregulator family, studied in neurological research contexts. Epithalon (AEDG) is the synthetic version of Khavinson's pineal tetrapeptide, studied in telomerase-activity and cellular-senescence models since the 1990s.
Which one should I choose?
Epithalon is carried in 10 mg, 50 mg and Pinealon in 10 mg, 20 mg, each lot with its own certificate. Which of those suits the work is yours to decide; everything here is research-use-only rather than guidance for use in a human or an animal.
Do both Epithalon and Pinealon come with a certificate of analysis?
Neither is in stock at the moment, so in each case the certificate is the one attached to the lot that arrives. A certificate belongs to a lot, not to a product. It is linked from the product page, and reports identity, purity by the stated method, and net peptide content for the material actually in that lot.
Which is cheaper, Pinealon or Epithalon?
Per mg, Epithalon at $2.18 against $4.25, taking each one's best size. By vial they start at $40.00 for Epithalon and $60.00 for Pinealon, which is the comparison most people make and the one that says least, because the two are not sold in the same sizes.
Is a milligram of Epithalon the same as a milligram of Pinealon?
By mass yes, by amount of substance no. Pinealon is 418.4 g/mol and Epithalon is 390.35 g/mol, a factor of 1.1, so a milligram of Epithalon holds roughly 1.1 times as many molecules. Two vials with the same number on the label are not the same amount of substance, which is what the molarity calculator converts.
