How it works

From setup to your first dose, in minutes.

No data-entry marathon. Add your compounds, set your protocol, log your first dose — and watch your levels come alive.

1

Add your compounds

Pick from 100+ peer-reviewed profiles — Test C, BPC-157, Tirzepatide, Tadalafil — or scan a vial with your camera.

2

Set your protocol

Frequency, dose, route — pre-loaded with the published range. Tune it to your goals or accept the standard.

3

Log & watch your levels

Voice, tap, or scan. Your blood level updates on the live PK curve the second you log a dose.

The features

Everything your protocol needs.
Nothing it doesn't.

Real-time PK modeling, AI bloodwork analysis, vial scanning, and a Mia that learns your body.

Live PK Modeling

Question
"How long after my last Test E should I wait before PCT?"
Test E has a half-life of ~10.5 days. Based on your last log (250 mg), wait until Jun 3 — that's 5 half-lives, when androgenic activity is biologically inactive.
Stack Audit
"What should I add to this stack for sleep?"
Your stack: Test C, Tirz, BPC-157. For sleep, the research-backed option is DSIP (100 mcg subQ pre-bed, ~7 min half-life, no AM grogginess).
Semaglutide compound detail — FDA approved, ~7 day half-life, 0.25–2.4 mg/wk dosing range, SubQ route, clinical uses and key benefits
