COA URL: https://essentialresearchlabs.com/coa

Notes: Reviewed September 14, 2026. PeptidePrices retained all 28 public /coa files (26 Freedom Diagnostics, 1 BioViridian, 1 MZ Biolabs). Twenty-five Freedom official PDFs match the vendor JPEGs on client, accession, lot, identity, purity, and content. Accession 2607090016 (ADX10 10mg) prints Identity Confirmed on the vendor JPEG and Failed on the official Freedom PDF; purity 99.28% and 13.61 mg otherwise match. The BioViridian Ipamorelin 10mg file names Wave Research and matches the official PDF. The MZ Biolabs Tesamorelin 10mg file names Eric R. Fong; MZ has no public registry. PeptidePrices does not treat PTA, Wave Research, or Eric R. Fong as Essential Research Labs. Zero certificates are counted as vendor-verified or attached to listings. About names Chromate and Janoshik; the live archive is Freedom, BioViridian, and MZ.

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.
