Does TrackPep give peptides dosing advice?

No, and it never will. TrackPep is a record-keeping and education tool: you enter what you were prescribed, and it keeps the log, the maths, and the reminders straight. Dosing decisions belong with your prescriber.

Does TrackPep work with a titration schedule?

Yes. Dose changes are part of the log, so your history shows what you were taking and when it changed — which is exactly the record a prescriber asks for at a review.

Tracking, done properly

A GLP-1 tracker that follows the whole protocol

Weekly injections, dose escalations, weight, hydration, and the side effects that come with them belong in one record. TrackPep keeps them together and shows the trend rather than the noise.

01 — What you get

Everything a peptides log actually needs

Six tools that work together, so your doses, vials, and results live in one record instead of four apps.

Inventory

Track vials, BAC water, expiration & remaining doses. Never run out mid-protocol.

Reconstitution calculator

Math you can trust. Convert mg per vial → syringe units in milliseconds.

Body-map injections

Rotate sites visually. Reduce lipohypertrophy with a calendar-aware map.

Side-effect log

Log symptoms with severity. Spot patterns across compounds & dose changes.

Weight & hydration

Beautiful trendlines that smooth daily noise. Goal-aware, never judgemental.

Privacy controls
