About TRT Companion
TRT Companion is the essential tracker for men on Testosterone Replacement Therapy — built to answer the question every patient has: is it actually working? Log your injections, track your blood work, monitor your wellness, and surface patterns that are easy to miss. Everything your treatment produces, in one place. TRACK YOUR PROTOCOL · Medications and injections – dose, volume, site rotation, next-dose countdown · Blood work panels – import from a PDF or enter manually, 40+ markers tracked over time · Daily wellness – energy, mood, libido, sleep quality, gym performance · Health metrics – resting heart rate, HRV, blood pressure, body mass (from Apple Health) · Injection site rotation so you never repeat a site too soon INSIGHTS THAT MEAN SOMETHING TRT Companion analyses your data and surfaces patterns: which markers are trending out of range, how your sleep affects next-day energy, whether your protocol change shifted your wellness score. Not guesswork – correlation across your actual data. BLOOD WORK, SIMPLIFIED Import your lab report as a PDF and the app reads it automatically. Every marker is mapped to reference ranges and flagged if it's outside. Trend lines show how you're tracking panel to panel. COMPOUND LIBRARY 200+ compounds used in TRT and adjacent protocols – from testosterone esters to ancillaries. Half-life, typical dose, and administration route, all in one searchable reference. DOCTOR-READY REPORTS Generate a clean summary of your protocol, recent blood work, and symptom history. Turn up to appointments prepared. AUGMENTED WITH APPLE HEALTH Pulls in sleep, resting heart rate, HRV, blood pressure, body mass, and step count – enriching your wellness picture and creating holistic insights.
