Why Batch-Level COA Transparency Matters for Your Research
A purity claim is only as credible as the evidence behind it. Generic COAs that don’t correspond to a specific batch are meaningless. At Midnight Sun Peptides, every Certificate of Analysis is batch-specific — meaning the document you see is the actual test result for the exact lot you receive, not a template or a historical sample result.
