Methodology

Source. Every night the index reads US research-peptide vendors’ public catalog pages and records each listed price and stated peptide content. No accounts, no checkout probing.
$/mg. Listed price divided by stated total peptide mass, in US dollars, excluding shipping. Blends and topical/cosmetic products are excluded from single-compound figures.
Daily median. For each compound and day, the median $/mg across that day’s comparable listings.
Monthly median. The median of that month’s daily medians. Medians are used because a single mislabeled or bulk-powder listing can distort a minimum; the live lowest price for each compound is on its price page.
Change in month. First to last observed daily median in the month, shown only when those days are at least 7 days apart. vs last month compares monthly medians.
Biggest movers rank compounds with at least 5 observed days by the size of the month-over-month change (or the in-month change when there is no previous month).
Vendors now is the vendor count when this page was generated, not a monthly average.
Gaps. A day the crawl missed has no row. It is left out of every figure, never interpolated.
