How this trend is computed
Each point is the median price per milligram across all qualifying Semax listings on that day: high/medium-confidence extractions from active research vendors, normalized to USD per mg, winsorized at the 5th and 95th percentile. Days with fewer than 5 distinct vendors are excluded entirely — no single vendor's pricing is ever identifiable. Full method on the price index page.
