Epithalon price comparison

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied in laboratory and animal models for its interactions with telomerase activity and circadian/pineal regulation. It is sold strictly for research use only and is not approved for human or veterinary use. This index tracks research-use-only vendor pricing for Epithalon so lab buyers can compare cost across suppliers.

Multi-peptide products (e.g. BPC-157 + TB-500). We don't rank these by $/mg — a per-milligram figure across different peptides isn't comparable — so they're listed separately by total price and kept out of the headline index above.

▸ Why compare $/mg for Epithalon?

Per-mg prices for Epithalon vary widely because vendors differ in synthesis scale, stated purity, vial size, and how lyophilization and shipping costs are bundled into the listed price. Comparing normalized $/mg across suppliers lets a researcher see the true unit cost and spot listings that look cheap only because of a small fill weight.

▸ Reading the COA

For Epithalon, confirm identity by mass spectrometry against the expected mass of the Ala-Glu-Asp-Gly tetrapeptide (molecular weight ~390.35 Da; monoisotopic mass ~390.14 Da), and check that HPLC purity meets or exceeds a stated threshold (commonly 98%+ for research material). Because it is a short peptide, watch the HPLC trace for truncation or deletion sequences (e.g., missing-residue fragments) and for residual acetate or TFA counterions, which can inflate net weight versus actual peptide content.

▸ FAQ

How is lyophilized Epithalon typically stored and handled in a lab?
As a lyophilized powder, Epithalon is generally kept sealed, desiccated, and protected from light, with long-term storage at freezer temperatures (commonly -20C or colder). Short peptides in solution are generally less stable than the dry powder, so material stability can be limited; consult the specific vendor's stated storage conditions on the label and COA. This is general material-handling information, not use guidance.
What is a COA and what should I check on one for Epithalon?
A Certificate of Analysis (COA) is a lab document describing a specific batch of material. For Epithalon, check that mass-spec confirms the correct tetrapeptide mass, that HPLC purity meets the stated percentage, and that the report lists batch/lot number, test dates, and any residual solvent or counterion content so you can verify identity and purity of the actual material you received.
Why do per-mg prices for Epithalon differ so much between vendors?
Differences come from production scale, stated purity grade, vial fill weight, and whether analytical testing (mass spec, HPLC) is included, plus packaging and shipping handling. A larger vial usually lowers $/mg, while extra testing or higher stated purity can raise it, so normalizing to cost per milligram is the clearest way to compare listings.
