Executive Summary

Certificate of Analysis (COA) Practices

Status: COA ✓ (third-party lab tested)

COA URL: https://endurapeptides.com/certifications/

Notes: Endura publishes 15 Freedom Diagnostics PDFs across the strengths listed in its current 11-product store. PeptidePrices opened BPC-157/TB-500 10/10mg accession 2605270239, GLP-3R 30mg accession 2605270236, and SS-31 10mg accession 2605270250. Each report confirmed LC-MS identity, HPLC-UV purity, and net content. The first two also included duplicate endotoxin passes at a stated sensitivity of 0.05 EU/mL; the sampled SS-31 report did not show endotoxin. The three Freedom search-code PDF URLs resolve at the lab host. Endura calls the lab accredited, but no accreditation identifier was visible in the sampled reports. Match the exact lot before relying on a report. 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.
