Executive Summary
Certificate of Analysis (COA) Practices
Status: COA ✓ (third-party lab tested)
COA URL: https://eternalpeptides.com/lab-tests/
Notes: Eternal's August 30, 2026 lab page exposed 43 distinct current Kovera verification links plus one current reconstitution-solution PDF, with previous-batch links retained under many product groups. PeptidePrices opened three current Kovera verification reports: 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 and includes lot linkage, LC-MS identity, HPLC purity, measured content, endotoxin, microbial sterility, and arsenic, cadmium, lead, and mercury results. The reports listed 99.329%, 99.337%, and 99.508% purity. The independent Finnrick dataset is less favorable: 10 of 27 tests pass its strict method, with repeated BPC-157 and Semaglutide concerns. Match the exact product, strength, and lot. Affiliate status does not influence the rating.

Rating Methodology
PeptidePrices rates vendors on a 1–10 scale using a transparent, weighted rubric:
- 40% COA practices — named third-party lab, batch-to-vial linkage, public on-site publication, testing breadth (HPLC purity, mass-spec identity, endotoxin, sterility, heavy metals)
- 20% Community reputation — Trustpilot weighted by review volume, Reddit/forum sentiment, documented red flags
- 20% Transparency — physical address, company age, ownership disclosure, contact info, domain age, return policy
- 20% Operations — shipping speed, customer-service responsiveness, payment flexibility, and dispute handling; affiliate-program performance is not scored
PeptidePrices is independent. No vendor has paid to increase their score. Full methodology at peptideprices.net/trust.
