Peptide Tracker Apps in 2026: What We Found When We Tested Them All

We tested every peptide tracker app in 2026. Here's what we found, including where our competitors beat us.

The peptide tracker market went from empty to 15+ apps in 12 months. We tested them all and scored them on what matters: safety features, PK modelling, multi-compound support, and price. Pinned is ours. We're transparent about that.

FOXO4-DRI

A D-retro-inverso peptide that selectively kills senescent cells by disrupting the FOXO4-p53 survival interaction, triggering mitochondrial apoptosis in aged 'zombie' cells while sparing healthy tissue.

FOXO4-DRI breaks the molecular shield that keeps senescent cells alive. By freeing p53 from FOXO4 sequestration, it triggers selective apoptosis in aged cells, restoring kidney function, testosterone levels, and tissue vitality in preclinical models.
