Evidence summary

Eon Peptides COAs and evidence

Testing history and coverage

Eon’s testing program has expanded considerably. The complete library retains 239 certificate files across 283 pages, representing 226 laboratory-report identities after repeated exports are reconciled. Eighty-five distinct reports name Eon Peptides across 88 files. Those Eon-named files span August 14 through October 22, 2026, with 49 dated in September and 38 in October. That sequence shows repeated testing activity across recent batches rather than reliance on a single launch-day certificate.

Seven-category ILS testing

The newest group adds 28 complete two-page reports from ILS Laboratories, each resolving to a specific official laboratory record. The peptide and compound panels cover purity, content, identity, heavy metals, microbial PCR, endotoxin and fentanyl. The water report includes pH and benzyl-alcohol measurements in place of peptide purity and content. Across the retained archive, 234 files provide numerical purity results from 99.00% to 99.99%, with none below 98%. Fifty-seven files contain at least four measured categories.

A complete current-batch example

The current PT-141 10 mg report is a strong example of the expanded testing. ILS recorded 10.39 mg and 99.90% purity, confirmed identity, reported five metals as not detected, and recorded no growth in the PCR screen. Its official endotoxin result is 0.031 EU/mL, and the fentanyl screen reports not detected. The complete two-page document and specific laboratory record are available together, so the results can be checked at their source.

Laboratories and supply chain

The archive also shows testing across repeated lots and different strengths. It includes 132 Freedom Diagnostics files, 76 Accurate Test Labs files, 28 ILS files, two pH Solutions documents and one Vanguard Laboratory report. Eon uses its own stock and third-party fulfillment stock, which accounts for certificates printed for Authentichain and wholesale suppliers. Each document retains its printed client, laboratory, batch and report date. Accurate Test Labs documents open with a neutral View COA control, while their original verification history remains part of the evidence record.

Individual report results

Purity and the amount in a vial are separate measurements, and the library preserves both. For example, an older Authentichain 5-Amino-1MQ document reports 12.83 mg against a 50 mg label, while a separate historical NAD+ file records 1098.97 mg against a 500 mg label. These results remain visible on their individual certificates alongside the larger body of recent testing. Current product rows use exact compound and strength matching rather than borrowing a certificate from another product.

Current prices

Eon has also reduced prices on many established sizes. Eighteen of the 33 directly comparable September catalog sizes are cheaper, and fifteen are unchanged. BPC-157 10 mg fell from $60 to $40, ARA-290 10 mg from $60 to $50, Wolverine Stack 20 mg from $100 to $80, and PT-141 10 mg from $45 to $30. These are the displayed single-vial prices. The store’s separate buy-one-get-one promotion is described separately from the recorded PEPTIDEPRICES offer.

Ordering and customer evidence

Ordering terms are clearly published. FedEx standard shipping is $8.99 and free above $200 after discounts. Orders paid before 2 PM Eastern qualify for same-business-day dispatch, with a stated 1–2-business-day transit estimate. The refund policy covers documented COA mismatches and allows unopened returns within 14 days. Building a larger, independently documented customer-review history is the main remaining opportunity to strengthen the overall evidence.

Horrible customer service

I have try to send messages in their inbox page, but They respond whenever they feel like it, and the order never arrived. I intend to file a complaint with my institution because they're deceiving me by claiming they're out of stock. They might have restocked the item the next day, but that will be tomorrow, and then another day, and so on.
