INJECTION & PROTOCOL TRACKER

Your injection protocols,
logged and tracked.

Pinned is the injection tracker built for the people actually running a protocol. Peptides, TRT, HRT, GLP-1s — whatever your stack: log doses, track your cycles, monitor your vial inventory, and keep your records in one place. No clutter.

STACK

Run the whole protocol

Multi-compound stacks side by side — cycles, on/off periods, titration ramps, pause & resume.

DOSE

Track your schedule

Set reminders around your cycle, log doses in a tap, and record your injection-site history.

MATH

Reconstitution math

Calculate BAC water, concentration, and draw units based on the vial values you enter.

STOCK

Vial inventory

Track remaining volume with every logged dose and estimate when a vial might run out.

SIGNAL

See your numbers

View adherence heatmaps, weight logs, and quality-of-life check-ins alongside the records you entered.

PRIVATE

Private by design

Your protocols, doses and health records stay on your device and never leave it — Face ID lock, no accounts, no ads. Export a PDF report when you choose.

Guides

These guides explain the arithmetic and the practices behind injection tracking: how concentration is derived, what a syringe unit actually measures, why sites are rotated, and how supplies are stored and travelled with. They stop where advice begins — no doses, no ranges, no schedules — which is a deliberate limit rather than an omission.
