TRT Vault
Stop guessing which side you pinned last week
Log every injection, chart your bloodwork, and know which site to rotate to next. Built for men on physician-prescribed TRT — everything stays on your iPhone.
What it does
Built for one job. It does that job well.
Injection site rotation
Log each shot with the site you used and the app suggests the next one, so you never hit the same spot twice in a row. Scar tissue is real — rotation matters.
Bloodwork that shows trends
Ten markers — Total and Free Testosterone, Estradiol, SHBG, Hematocrit, Hemoglobin, LH, FSH, Prolactin, PSA — charted against adult-male reference ranges. Labs sort by drawn date, not the day you got around to logging them.
Your protocol, on schedule
Weekly, every-other-day, split-weekly, or bi-weekly. Set your regimen once, get reminders, never miss a dose.
A cited compound reference
18 TRT-relevant compounds — testosterone esters, AIs, SERMs, gonadotropins, DHT managers — every entry cited to FDA labeling, DailyMed, PubMed, and the Endocrine Society. No forum lore.
100% local storage
No cloud, no account, no analytics SDK. Every dose, lab, and note lives only on your iPhone, and you can wipe it all from Settings.
Screens
See it before you download it.
Every dose and lab stays on your iPhone
TRT Vault uses 100% local storage — no cloud, no account, no analytics SDK, no third-party data sharing. Your injection history, bloodwork, and notes never leave the device, and you can erase everything from Settings at any time.
FAQ
Straight answers.
Is TRT Vault free?
The download and the compound reference database are free. The tracking tools — dose logging, regimen scheduling, bloodwork timeline, and site rotation — require Pro at $9.99/month or $69.99/year (42% off). Cancel anytime in Settings.
Where does my data go?
Nowhere. Everything is stored locally on your iPhone — no cloud, no account, no analytics SDK, no third-party sharing. You can clear it all from Settings whenever you want.
Do I need an account?
No. No sign-up, no email, no login. Download it and start logging.
Will it tell me what dose to take?
No. Dose ranges in the reference database are labeled as reported in literature, never recommendations. The app doesn't suggest protocols and doesn't link to any vendor.
Is this medical advice?
No. TRT Vault is a passive tracking and reference tool, not a medical device. It's for logging a regimen already prescribed by a licensed healthcare provider — talk to your doctor before starting, stopping, or changing anything.
Who is this app for?
Men on physician-prescribed testosterone replacement therapy who want their injections, labs, and rotation history in one private place. If you also use Peptide Vault, the two apps are built to work side by side.
