Cross-vendor view of every Certificate of Analysis for GHK-Cu: purity distribution, test coverage gaps, recent batches. Sourced back to the original COAs.
Each dot is one COA. Color = vendor. The dashed line is a recency-weighted rolling mean (6-month half-life) — it tells you whether testing is trending up or down across the corpus, independent of which vendors happen to have published most recently. Tightly clustered points across many vendors = either real consistency or rubber-stamping; check the individual labs.
