Peptide Trends
Discover what the research community is exploring. These are the peptides the most Peptide Library researchers calculated, added to a watchlist or inventory, tracked, searched for and read about this week, each researcher counted once.

How Peptide Trends works
What we count
Unique researchers, not taps. Someone who runs the calculator ten times for one peptide counts once. Signed-in researchers are counted by account; signed-out ones by an anonymous device id.
Time periods
Each period is whole days in UTC, ending yesterday, and is compared with the period of the same length just before it. All Time is compared with the all-time ranking a week earlier. Data refreshes hourly.
Percentages
A percentage is the share of researchers who did that activity on any peptide in the period. One researcher can explore several peptides, so a list’s percentages can add up to more than 100%.
Growth and movement
Growth is shown only when both periods had enough activity to compare meaningfully. Rank arrows compare with the previous period; NEW means it wasn’t ranked then.
Privacy
Trends show percentages, never head counts: shares of researchers, growth, and charts of relative interest (100% is the chart’s highest point). A peptide appears only once enough researchers explore it, and very small chart points are hidden. No individual’s activity, doses or schedules are ever shown. You can leave Community Trends in Settings.
Not advice
Trends reflect what the Peptide Library community is researching. Popularity says nothing about safety, effectiveness or approval, and nothing here is a medical recommendation.
