Why athletes pick it

Everything dialed in,
nothing left to guess.

A single dashboard for compounds in circulation, weekly load, body composition, and personal records — built for serious protocols.

Active compound levels

Real-time serum modeling for TRT esters, peptides, and oral compounds — see exactly what's circulating, right now.

PR-anchored insights

Tie every personal record to the protocol that produced it. Bench, squat, deadlift — with the compounds that fueled the lift.

Smart dose schedule

Calendar-aware dosing with timing windows, reconstitution math, and inventory across vials and peptides.

Energy & sleep markers

Daily subjective markers — energy, libido, sleep, irritation — overlaid on your protocol so you can see what's working.

Body composition

Weight trends with a 14, 30 and 90-day view. Spot momentum and plateaus before they become problems.

Private by default

Your data stays on your device. No accounts, no cloud, no surveillance. Export when you want, never required.

One protocol view for everything you take.

Open the app and your week is laid out — TRT, peptides, orals — color-coded and timestamped, side by side.

Active compounds, always current.

See exactly what's circulating right now — dosed, modeled, and updated the moment you log.

Hit a PR? Capture the protocol that got you there.

Each personal record stores the active compounds at the moment it happened — so you can repeat what works.
