Tracking a Retatrutide Schedule

This page is about the record, not the regimen. It explains why retatrutide tracking tends to follow a weekly pattern and what a good log captures. It does not contain a dose, a titration amount, or a schedule for you to follow.

What retatrutide is

Retatrutide is an investigational triple agonist, acting on the GIP, GLP-1 and glucagon receptors. It is in Phase 3 clinical trials and is not approved by any regulator for any use. Because it is unapproved, there is no label, no authorised dosing, and no clinician-facing guidance for it outside of trial protocols. Anything you have read about what it does or how well it works comes from trial reporting, not from an approved indication, and this page makes no claim either way.

Why the tracking follows a weekly pattern

Structurally, people who log retatrutide log it on a weekly cadence: one entry per week, on the same day, stepping up over time in stages set by whoever directs their use. That shape comes from the trial design and is the reason a log for it looks different from a daily-injection log. Two things follow from it. First, a missed week is a bigger gap than a missed day, so the record needs to make a missed week obvious at a glance. Second, each titration step is a change in what you are doing, and the date of that change is the single most useful fact in the whole history when you look back. To be plain: this page provides no doses and no titration amounts. The figures belong to you and the person directing your use, and the log exists to record what those were, when.

What matters in tracking it

Consistent day and time — pick the day, pick the clock time, and record the actual time each week. Drift is invisible until it is written down.
Site rotation — weekly does not mean the site gets a week off by default; it means you have fewer injections to spread across your zones, so it is tempting to reuse the easy one. Follow a fixed sequence; see the rotation guide.
Reconstitution records — note the water volume and concentration for every vial. A weekly draw from a vial that lasts several weeks is exactly the situation where a forgotten concentration becomes a wrong draw. The reconstitution calculator converts the figures you already have.
Weight trend — a weekly weight on the same morning, in the same conditions, alongside the log. The single number never means much; the line over months is the part worth keeping.
Titration dates — every time the amount changes, log the date it changed. That turns a list of injections into a history you can read.

The record is the point

With a weekly compound, there are relatively few entries, which makes each one matter more. A clean log of day, time, site, vial, weight and any change in step gives you and whoever directs your use something real to look at. The general method is in how to track peptide cycles properly; the reconstitution working is in the reconstitution guide.

This page describes record-keeping only. It does not recommend retatrutide or any other substance, and it provides no dose, titration amount, or schedule. Retatrutide is investigational and not approved for any use.

Pepti’s peptide tracker app keeps the weekly log, the site sequence, the vial count and the weight trend in one place.
