What makes Epithalon different to source
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.
The top 3, explained
Purgo Labs
10/10Affiliate partnerWhat 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 (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
MyPurePeptide
10/10Affiliate partnerWhat we can verify
Janoshik Analytical report #223088 for BPC-157 10mg batch 10242025B2 (sample received 17 Aug, analysed 24 Aug 2026): 11.61mg measured, purity 99.635%. We opened it on the lab's own verification page (key 1GTY19EIMQE4) on 30 Sep 2026 — client, manufacturer and batch print as MyPurePeptide. A public COA directory lists 103 report records across 47 products, each with task number, verification key, report batch, the original report image and the sample photograph, plus endotoxin reports for most lots; every product page links its current report. Open catalog with sized prices (BPC-157 10mg $25; TB-500 10mg $25; GHK-Cu 100mg $35; Ipamorelin 10mg $25; Tesamorelin 10mg $40; NAD+ 500mg $35). Legal entity myPurePeptide LLC with a mailing address in Austin, Texas; Visa and American Express at checkout. Trustpilot 4.8 across 247 reviews (read 10 Oct 2026), claimed December 2025.
Net content: Report states 11.61mg measured on a 10mg label (116% — just over our 115% flag line), purity 99.635%; TB-500 #223097 11.54mg / 99.007%
Where it falls short
The printed address (12407 N Mopac Expy Ste 250 PMB 570, Austin) is a commercial mailbox, not premises — identity is awarded on the named LLC with that disclosure. The BPC-157 report measures 11.61mg on a 10mg label, 116% — just over our 115% flag line; TB-500 10mg measured 11.54mg. The vendor's own site says a report 'alone does not confirm the lot shipped'. The GLP-class pages print strike-through reference prices far above the selling price (Semaglutide 10mg 'was $399.99', now $70; Retatrutide 10mg 'was $699.99', now $80) — treat the 'you save' figures as marketing. Zelle is offered alongside cards. Returns: 7-day unopened window with a continuous unboxing video required for damage claims. A domain lookalike (mypurepeptides.com) is disclaimed on the vendor's homepage.
Oneday Compounds
10/10Affiliate partnerWhat we can verify
Read 29 October 2026 through a registered account (prices and the COA library sit behind a login). A WooCommerce store with 49 listings, sized pricing on each, all shown at 40% off a struck list price during a rebrand to 'BY ONEDAY' (BPC-157 10mg $23.99 from $39.99; TB-500 10mg $29.99; NAD+ 500mg $35.99; GHK-Cu 50mg $20.99; MOTS-c 10mg $26.99). The COA library carries 57 entries, every one with at least one lot-numbered certificate, and the links open on ILS Laboratories' own portal: the retatrutide ('OC-3RT') 10mg report COA-2026-3WBETH, lot OC-RT10-106, analysed 2 Sep 2026, reads 99.63% purity, identity retatrutide confirmed, net content 10.31 mg on a 10 mg label, with three vials averaging 10.37 mg, sterility (USP 71), endotoxin and heavy metals passed. Product pages print the lot shipping (BPC-157 10mg: OC-BPC10-104, 99.82%, 10.30 mg). Oneday Enterprises, LLC d/b/a Oneday Compounds, 2326 Washington Blvd, Fourth Floor, Ogden, Utah.
Net content: COA-2026-3WBETH (OC-3RT 10mg, lot OC-RT10-106): net content 10.31 mg on a 10 mg label, three vials 10.22 / 10.31 / 10.59 mg, purity 99.63%, identity retatrutide confirmed; BPC-157 10mg lot OC-BPC10-104 10.30 mg, 99.82%
Where it falls short
Prices and certificates need a free account (no purchase), which since 1 November 2026 no longer costs the ungated point. All sales are final, with damage to be reported within 24 hours; checkout takes cards, but Zelle carries a 5% discount and the FAQ still lists only Zelle, Cash App, Venmo and ACH. The product pages say 'up to 12X' (ILS lots) and the cart says 'up to 16X'; both hold, because Oneday's Ethos Analytics reports carry a wider panel (checked on CJC-1295/Ipamorelin lot OC-CJI10-104, 1 November 2026). GLP-class products are sold by code (OC-2TZ, OC-3RT); the lab confirms retatrutide for OC-3RT.
Purgo Labs for Epithalon
Purgo Labs sits at #1 of 28 on this page: 10/10 on the rubric, 10mg at $29.99 read 8 Nov 2026. Code HEALTH gives 30% off eligible products. We earn a commission; it did not decide the order above.
Before you order, check the batch
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.
Buying Epithalon — frequently asked
Where can I buy Epithalon?
As of 8 Nov 2026, 28 of the 106 vendors on our scoreboard list Epithalon with a price we have read on the product page: Purgo Labs, MyPurePeptide, Oneday Compounds, Premier Bio Labs, Rivn Peptides, Ameano Peptides, Snap Peptides, ezPeps, Pure Lab Peptides, Xcel Peptides, Pure Peptides, Oath Research, PS Peptides, Amplified Labs, Blue Ridge Peptides, Everest Peptides, Nexaph, Crush Research, Loti Labs, ZC Labs, Peptide Partners, GigaCompounds, Value Research Labs, Puratek Peptides, Blue Sky Peptide, Peptide Pros, Peak Lab Peptides, Elite 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.
Who sells the cheapest Epithalon?
At the 10mg size, the lowest price we have on record is Nexaph at $14.30 (read 26 Oct 2026) — Store API · sold as 'Epitalon 10mg (10 vials/kit)' $143.00/kit on sale, regular $168.00 · per-vial = kit ÷ 10. It scores 8/10 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.
Which Epithalon vendor has the best documentation?
Purgo Labs, MyPurePeptide, Oneday Compounds, Premier Bio Labs 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.
Is it legal to buy Epithalon?
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.
How is this list ordered?
Rubric score first. Among equal scores, our editorial pick (Purgo Labs) comes first, then a short, named list of affiliate partners we choose to list first inside a tie, then the lower verified price per milligram at 10mg, then the larger independent review base. 15 of the 28 vendors here are partners. A partnership never changes a score and never moves a vendor above one with a higher score.
Are Epithalon and Epitalon the same thing?
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.
Why do vendors sell epithalon in such large vials?
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.
