Where to buy Epithalon (also sold as Epitalon, Epithalone, AEDG peptide): the 7 vendors below are the ones we have a dated product-page price for, ranked on documentation first and price second. Nothing here is typed from memory — every number links to a date.
Reference size 10mg — the size most of these vendors sell. Other sizes we have on record are listed per vendor.

Epithalon is a four-residue peptide (Ala-Glu-Asp-Gly), which makes it one of the simplest and cheapest compounds to synthesise on the research market. That shows up in the catalogs two ways: it is sold in unusually large vial sizes, and the price per milligram varies more between vendors than the synthesis cost can explain.
The spelling is inconsistent — Epithalon, Epitalon and Epithalone all appear, sometimes on the same site — and search results split across them. They are the same compound. What differs between vendors is the vial size and, as always, whether the certificate can be checked against the laboratory that issued it.
Because vendors sell it at sizes from a few milligrams to tens of milligrams, the reference size used to order this page is the size most vendors carry; the per-vendor rows list every size we have a dated price for.
What we can verify
Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Net content: Measured net peptide published per lot (e.g. BPC-157 lot PL-BPC-05: 11.16mg vs 10mg label)
Where it falls short
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
What we can verify
Public COA & Batch Verification Ledger covering 44 products and 87 batches with 539 COA links, including 380 Janoshik Analytical references (ISO 17025) and 141 Vanguard references. 4.9 across 311 Trustpilot reviews.

Where it falls short
Catalog includes hormone-class products (HCG, HGH 191AA, HMG) alongside peptides, a regulatory-sensitive class. Not an affiliate partner — we earn nothing from this vendor, and it ranks where the rubric puts it.
What we can verify

Where it falls short
The homepage advertises a 30-day money-back guarantee while its own FAQ says all sales are final. A live NAD+ batch was listed with 'no COA yet' despite the every-batch claim. No standalone semaglutide or tirzepatide; retatrutide only as a blend.
Purgo Labs sits at #1 of 7 on this page: 10/10 on the rubric, 10mg at $23.99 read 23 Sept 2026. Code HEALTH gives 20% off every order. We earn a commission; it did not decide the order above.

A ranking tells you which vendors have good practices; it cannot tell you about the specific vial you receive. When your order arrives, compare the batch number on the label to the certificate. If they do not match, or there is no batch number, the documentation does not cover what you were sent, regardless of who you bought from. How to read a peptide COA.
As of 23 Sept 2026, 7 of the 59 vendors on our scoreboard list Epithalon with a price we have read on the product page: Purgo Labs, Chameleon Peptides, Ameano Peptides, Rivn Peptides, Everest Peptides, Puratek Peptides, PS Peptides. Every one of them is scored on the same 10-point rubric; the table above shows the score, the dated price and what you can verify before ordering.
At the 10mg size, the lowest price we have on record is Purgo Labs at $23.99 (read 23 Sept 2026) — sale; list $29.99 struck. It scores 10/10 on documentation. Price is the second sort key on this page, not the first, because an underdosed vial at a low price is the most expensive outcome.
Purgo Labs and Chameleon Peptides share the top score at 10/10: named laboratory, certificates that resolve on the laboratory's own site, measured milligrams against the label, and a published legal identity. The per-criterion evidence, with dates, is on each vendor's review page.
Epithalon is sold by these vendors as a research chemical for laboratory use, not for human consumption; none of it is FDA-approved in this form. Legality of purchase varies by jurisdiction and the compound, and it is your responsibility to know your local rules. Our pages assess documentation and pricing; they are not legal or medical advice.
Rubric score first. Among equal scores, the lower verified price per milligram at 10mg. Then the larger independent review base. Affiliate partnership is not an input: 5 of the 7 vendors here are partners and they sit wherever the evidence puts them.
Yes. Both spellings, and occasionally Epithalone, refer to the same tetrapeptide Ala-Glu-Asp-Gly. Vendors are not consistent, so search both spellings on a catalog before concluding a vendor does not sell it.
It is a short peptide that is inexpensive to make, and much of the published research used relatively large total amounts. Vendors respond with larger sizes. Compare vendors on price per milligram at the same size rather than on the headline vial price, and note that a larger vial does not change the documentation question.
