What it does

Built for one job. It does that job well.

01

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.

02

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.

03

Your protocol, on schedule

Weekly, every-other-day, split-weekly, or bi-weekly. Set your regimen once, get reminders, never miss a dose.

04

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.

05

Your health data stays on-device

No cloud sync, no account. Every dose, lab, and note lives on your iPhone, and you can wipe it all from Settings.

Every dose and lab stays on your iPhone

Your injection history, bloodwork, and notes are stored locally — no cloud sync, no account required — and you can erase everything from Settings at any time.

FAQ

Straight answers.

Is TRT Vault free?

The download is free. TRT Vault Pro unlocks the app — dose logging, regimen scheduling, bloodwork timeline, site rotation, and the compound reference — at $9.99/month or $29.99/year. Cancel anytime in Settings.

Where does my data go?

Your health data — injections, labs, notes — is stored locally on your iPhone with no cloud sync and no account. 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.
