Core Research Peptides review: 60/100, real store, testing gaps

As of October 2026, Core Research Peptides (coreresearchpeptides.com, domain registered May 2026) publishes an HPLC and LC-MS report for each product, mostly from Janoshik Analytical, verifiable with Janoshik's key. Its COA library lists no lot numbers, so reports can't be matched to a vial, and it has no independent test record. It is not the same company as Core Peptides.
