The Peptide Popularity Report 2026
What America is actually searching for in peptides, ranked by real monthly Google demand and 12-month momentum.
Tirzepatide is now the most-searched peptide in the US, with about 823,000 average monthly Google searches, and it is still climbing while semaglutide slips. Across the peptides tracked here there are about 2,742,700 monthly searches. This report ranks the most-searched and the fastest-rising peptides of 2026, from real search data.
The most-searched peptides in 2026
These are the individual peptides Americans look up most, by average monthly Google searches. Each row shows what the peptide is typically used for, so you can read this as both the most-searched and the most-used list. GLP-1 weight-loss molecules dominate the top, while recovery, longevity and skin peptides fill out the rest. For the full picture by category, see the by-goal breakdown below.
| Peptide | Monthly US searches | Goal |
|---|---|---|
| tirzepatide | 823,000 | Weight loss |
| semaglutide | 368,000 | Weight loss |
| retatrutide | 368,000 | Weight loss |
| glutathione | 165,000 | Skin & antioxidant |
| oxytocin | 165,000 | Sexual health |
| nad+ | 135,000 | Cellular health |
The fastest-rising peptides
Ranked by 12-month growth in search demand, comparing the most recent quarter with the same quarter a year earlier. GHK-Cu, KPV and retatrutide are drawing the sharpest new interest.
The GLP-1 crown is shifting from semaglutide to tirzepatide
The two biggest weight-loss peptides are moving in opposite directions. Tirzepatide search demand climbed to a 12-month high, while interest in semaglutide slipped by roughly a third over the same year.
The newer molecule is now the one people look up first. For anyone tracking where weight-loss demand is heading, tirzepatide is the clearer signal in 2026.
What people search for, by goal
Grouping the peptides by what they are used for shows where attention sits. Weight loss leads by a wide margin, followed by recovery and muscle support.
How this report was built
Figures are average monthly US Google search volume and 12-month trend per peptide, pulled from a commercial keyword dataset in July 2026. Search interest reflects curiosity, not medical use, effectiveness, or sales. Fastest-rising compares the most recent three months with the same quarter a year earlier. pru updates this report quarterly.
