What we reviewed, with the limits of that evidence kept explicit.
Eternal Peptides is a US research storefront. Its site identifies Cenvira LLC and lists Little Neck, New York 11362. It publishes support@eternalpeptides.com and a text support number. The site accepts cards, Zelle, and Bitcoin. It states that paid orders process within 24 hours.
The public Lab Tests page exposed 43 distinct current Kovera verification links plus one current reconstitution-solution PDF during the August 30, 2026 rescrape, with previous-batch links retained beneath many product groups. PeptidePrices opened current Kovera reports for BPC-157 10mg lot EP-260521-BPC10, Retatrutide 10mg lot EP-260514-RE10, and BPC-157/TB-500 5mg/5mg lot EP-260514-BT05. Each report names Eternal Peptides. Each one includes LC-MS identity, HPLC purity, measured content, endotoxin, microbial sterility, and arsenic, cadmium, lead, and mercury results.
The three sampled reports listed 99.329%, 99.337%, and 99.508% purity. Finnrick lists 10 passes and 17 failures across 27 tests under its unusually strict method. Some high-purity results can still miss that method's threshold. Its current page gives Eternal a 63% rating, with the weakest product records in BPC-157 and Semaglutide. This classification is the slight drawback that keeps the COA factor from a perfect 10.
No mature exact-domain independent customer-review aggregate was found. Reddit discussion is mixed. One complaint thread says that Eternal later reshipped and resolved the problem. Another thread questions a difference between a vendor-posted BPC-157 report and independent results. The owner reviewed these mixed signals and set reputation at 6.5. Eternal receives 8.5/10 from COA 9.5, reputation 6.5, transparency 8, and operations 8.5. Affiliate status does not affect the score.

Decision guide
Customer reputation
Customer reviews describe service and order experiences. They do not prove identity, purity, vial content, sterility, or manufacturing standards. We keep them separate from COA and independent-testing evidence.
Finnrick is independent product-testing evidence, not a customer-review platform. Its strict method shows stronger Retatrutide, Tirzepatide, and Melanotan II results than BPC-157 and Semaglutide results.
