Our Verdict
Core Peptides uses Vanguard Laboratory — the same ISO/IEC 17025:2017 accredited lab used by Licensed Peptides and Certified Pep — for independent third-party purity testing. All recent COAs (April 2026) are batch-specific, with lot numbers traceable to individual production runs. Tested products show purity between 98.16% and >99.80%. They have a confirmed physical address and contact info, but no ownership disclosure and no Finnrick coverage. At this tier, Core Peptides is a legitimate, well-documented vendor with real independent verification. The remaining gaps are ownership transparency and community review history.
