Joust

Log your protocol. See what works.

Joust is a progress tracker that logs your compounds and your outcomes together — doses, weight, bloodwork, and labs on one timeline.

Know what's actually working

Joust surfaces what changed in your numbers — and the dose change that lines up with it. See how your body responds to each adjustment, not just that something happened.

What you're after, on your timeline

Set what you're working toward — cut to a target weight, hold testosterone in range, watch how your markers respond. Joust shows your dose history next to the metrics that matter.

If you can dose it, Joust can track it. You bring the compound and the dose. Joust handles the schedule, the timing, and the record for every compound in your stack.

Lyophilized vials

Vial mass, BAC water volume, target dose — Joust calculates units to draw and tracks the BUD from the moment you mix.

Inventory tracking

Doses remaining across every compound in your stack, with reorder reminders timed so you never run out.

Fasting windows

Window-open alerts, a live countdown to your dose, and post-dose fasting tracked through the whole loop.

Daily, weekly, or as needed

Create your dosing plan. Steady, titration, or cycle on/off. Joust tracks each dose, reminds you when it's time, and lets you know when your plan calls for a change.

Steady
Same dose, same days, every week.
Titration
Ramp the dose up week by week to find your protocol.
Cycle on/off
Alternate an on phase with an off phase.
