P3 Labs

Executive Summary

Certificate of Analysis (COA) Practices

Status: COA ✓ (third-party lab tested)

COA URL: /coa-library?vendor=P3%20Labs

Notes: Reviewed September 18, 2026. All 18 one-page PDFs name P3 Labs or P3 Labs LLC and match official BioViridian records. Every report includes identity, purity, and measured-content results. Seventeen current product-and-strength rows receive exact controls; an older NAD+ 500 mg report remains available as historical evidence. The archive does not include endotoxin, sterility, or heavy-metals panels. P3 Labs storefront labels GLP-R3 and GLP-T2 remain unchanged on public listings.

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.
