Score overview
How we score →Weighted composite across 8 criteria; the letter grade follows our published bands and integrity gate.
Key facts
Pros
- Genuine, correctly-attributed independent Janoshik per-batch testing program (~40+ reports on /lab-tests/, 2024-06 to 2025-08); five personally opened, all naming Eternal Peptides as client and manufacturer and spanning HPLC purity (Selank 99.920%, TB-500 99.007%), content quantification and microbial sterility, each with a janoshik.com verify key
- Transparent and buyer-friendly: named New York LLC (Cenvira LLC) with address, published terms and NY governing law, thorough research-use-only labeling, clean tech (HTTPS + HSTS preload + CSP + nosniff, no dark patterns), competitive US-market pricing with vial sizes (BPC-157 5mg USD34.99 / 10mg USD64.99), fast tracked USPS Priority/Express shipping, all three payment rails (card, Zelle, Bitcoin) and positive Trustpilot (4.6/5, ~59 reviews) plus positive Reddit sentiment
Cons
- Contradictory refund policy: the Shipping/Returns page advertises a 7-day no-questions-asked return of unused/unopened items, while the Terms page states all sales are final with no refunds under any circumstances; there is no reship or money-back guarantee for lost, seized or failed packages
- Coded GLP product naming obscures that GLP-1 (S) / GLP-2 (T) / GLP-3 (R) are semaglutide / tirzepatide / retatrutide; the graded domain (eternalpeptides.net) is now only a redirect to the ~14-month-old eternalpeptides.com; and several COAs are content/sterility rather than HPLC purity and sit on a central lab-tests page rather than embedded on each product page
