Trace: Peptide & TRT Tracker

New: AI Insights finds non-obvious patterns in your dose, check-in, and lab data. Private through AIProxy.

Trace is the private logbook for anyone on peptides, TRT, or HRT.

Log your doses, rotate injection sites, track symptoms, and see the long arc of your protocol — all on your device, all yours.

FOR GLP-1 USERS Track your weekly shot, ramp up titration, see weight drop against your dose timeline. Built-in templates for tirzepatide, semaglutide, and retatrutide.

FOR TRT USERS Log injections, monitor labs (testosterone, estradiol, SHBG), track mood and energy across cycles. Supports weekly, twice-weekly, and HCG-combo protocols.

FOR HRT + PERIMENOPAUSE Log estradiol, testosterone, and progesterone. Track how symptoms change week to week.

FOR RESEARCH PEPTIDE USERS BPC-157, Ipamorelin, CJC-1295, Sermorelin, GHK-Cu, TB-500 — every compound on one timeline. Reconstitution math shown as reference, never prescription.

PRIVACY FIRST No account. No cloud unless you opt in. No tracking pixels. Your data stays on your device. Face ID lock optional.

Trace is a logbook, not medical advice. It doesn't diagnose, prescribe, or recommend doses. Always follow your prescriber's plan.

Made for grown-up power users — TRT guys, GLP-1 patients, perimenopause, biohackers, and anyone serious about their protocol.
