Executive Summary
Certificate of Analysis (COA) Practices
Status: COA on request
COA URL: https://pristineaminos.com/testing/
Notes: Pristine's Testing page claims HPLC, mass-spectrometry, sterility, and endotoxin testing for each lot. It also claims ISO/IEC 17025:2017 accreditation. PeptidePrices found no downloadable report, named laboratory, batch table, accession number, search code, or working public lookup on that page, including while signed in. A separate Welcome page names Krause Analytical but provides no report identifier that can be checked. The homepage sample lot text is not a COA. Request the full report for the exact product, strength, and lot before relying on any panel claim. 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.
