What it does

Log in one tap

Next dose on a countdown ring, a week strip, Site Rotation Compass and a 5-second Undo. Pens stay simple; vials get counted.

Every vial, counted

Enter what your pharmacy label says once. PeptideUp counts the doses left and runs the 28-day clock from the day you mix. It keeps your numbers; it never works them out.

See where you're headed

A projected trajectory from your own weigh-ins, estimated medicine level, protein and water targets. Estimates, never promises.

Cold Vault

Every pen and vial with its freshness clock. Mixed vials get a 28-day countdown and a nudge three days before it ends.

Scan your plate

One photo, four macros with their likely range, portion pills and steppers to fix anything the camera got wrong.

Ask Pengu

Knows your logs, answers in plain English, shows an action card before it ever writes anything. Never a dose, never a compound.
