Testosterone intelligence platform
Know your levels.
Own the trend.
Population testosterone fell about 1.2% a year across the cohort that measured it — and most men have never seen their own numbers at all. TestoTrack turns scattered lab results into one clear trend line, with an AI coach that explains what your numbers mean and what to do next.

AI coach: trend improving
The silent decline
A generational drop, hiding in plain sight.
~1.2%
per-year decline in male testosterone measured across a US cohort from 1987 to 2004 — independent of aging
Travison et al., JCEM 2007 ↗38.7%
of men aged 45 and over seen in US primary care met the biochemical criteria for hypogonadism
Mulligan et al., Int J Clin Pract 2006 ↗2 draws
are what guidelines require before a diagnosis — one morning result is a data point, not an answer
Bhasin et al., JCEM 2018 ↗Fatigue, low drive, slow recovery, brain fog — symptoms get dismissed as “just getting older.” The data says otherwise. The problem isn't that testing doesn't exist. It's that nobody is tracking.
