Where to buy Epithalon (also sold as Epitalon, Epithalone, AEDG peptide): the 6 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.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.
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
Names Freedom Diagnostics (Nashville) as its per-batch testing lab — the same laboratory Purgo Labs uses. 43-product catalog with public sized pricing. 4.9 across 561 Trustpilot reviews on a claimed, active profile (read 19 Sep 2026). Free same-day shipping (order by 12pm CT), 30-day money-back, published street address in Gallatin, TN.
Net content: Certificate reports 1.19mg measured vs 1mg label, 99.76% purity
Where it falls short
Scored 10/10 on 19 Sep 2026, up from 8/10, and the timing is disclosed rather than buried: Rivn became an affiliate partner the same day, and that is what prompted the re-read. The two points it had been missing came from a single on-site '4.9 (1,247 reviews)' widget that contradicted the real Trustpilot record; that widget is gone, no in-house review count replaced it, and a searchable 47-certificate library now sits where seven loose images were in August. Full evidence and the exact pages checked are in the score history. Still vendor-stated and unverified: 'ISO 9001 certified facilities', 'Certified GMP', and the lab's ISO/IEC 17025 accreditation — claims we note but do not score.
What we can verify
Names Janoshik Analytical; certificates link to Janoshik's own verify portal with lot codes, viewable before purchase without an account. 4.7 across 407 Trustpilot reviews. Ameano Peptides LLC with a published Little Rock, AR street address and phone. 75-product catalog with sized pricing.
Net content: Janoshik report #163728 (BPC-157 10mg, batch BPC1005082026-22) states 12.09 / 12.25 / 12.18 / 11.95mg measured vs 10mg label, purity 99.9%, key VKEUQS8HE1UW — read 6 Sep 2026
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 6 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, 6 of the 78 vendors on our scoreboard list Epithalon with a price we have read on the product page: Purgo Labs, Rivn Peptides, Ameano Peptides, PS Peptides, Everest Peptides, Puratek 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 leads 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 6 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.
