The idea

Peptides come with homework: reconstitution maths, schedules to remember, logs spread across notes and spreadsheets. Peptmate is a tracker, not a dosing coach. The plan comes from a healthcare professional; the app does the maths and keeps the record.

What it does

Everything the plan needs, in one app.

Reconstitution calculator

Vial strength and water in. Units to draw out.

Schedules and reminders

Daily and weekly plans, with a reminder at the right time.

One log

Doses, mood, weight and journal, all in one place.

Library

Plain language summaries, and lessons under three minutes.

Insights

Adherence, on time doses and injection site rotation.

Exports

PDF, CSV or text, ready for your next appointment.

Free on the web

The maths, open to anyone.

Six free calculators on peptmate.com. Change any input and the syringe mark updates with it.
