Tracking GLP-1 Peptides (Semaglutide & Tirzepatide): A Complete Guide

GLP-1 receptor agonists like semaglutide and tirzepatide are unusual among peptides: the dose is deliberately titrated upward over weeks, the effects build slowly, and side effects often track the dose changes. That combination makes good record-keeping unusually valuable — without it, you can't tell whether last week's nausea came from the dose increase or something you ate, or whether the scale is actually moving.

Why GLP-1 protocols need careful tracking

• Titration: doses step up on a schedule, so you need to know exactly when each change happened.
• Slow signal: weight and appetite shift over weeks, not days — only a trend reveals what's working.
• Side-effect timing: nausea, fatigue, and GI effects often appear right after a dose increase; a log makes the pattern obvious.
• Weekly cadence: a once-weekly injection is easy to misremember — "did I dose Sunday or Monday?" is a question your tracker should answer.

What to log each week

The dose

• Compound (semaglutide, tirzepatide, or other) and batch/vial.
• Dose in mg or mcg, plus the units drawn on your insulin syringe.
• Date and time of the injection — critical for a weekly schedule.
• Injection site, rotated each week.

The response

• Body weight, ideally a consistent weekly weigh-in.
• Appetite and cravings on a simple 1–5 scale.
• Side effects: nausea, fatigue, GI changes, and how long they lasted.
• Energy, sleep, and mood so you can separate real progress from a rough week.

Tracking the titration schedule

The single most useful thing you can do on a GLP-1 protocol is keep a clean record of when each dose step happened. With that, every later observation — weight, appetite, side effects — can be read against the dose that was actually in effect at the time. A peptide tracker app timestamps each dose automatically, so your titration history assembles itself as you log, instead of living in your memory.

Need to convert your vial and BAC water into a draw volume for a specific dose step? The free reconstitution calculator does the math in mL and insulin-syringe units.

Reading the trend

After a few weeks, the questions that matter become answerable: Is weight trending down at a steady rate, or has it stalled? Did appetite suppression hold after the last increase, or fade? Did side effects settle within a few days of each step? This is where charts earn their keep — in LynkDose, your weekly weight (synced from Apple Health) is plotted directly against your dose history, so a stall or a plateau is something you see, not something you guess at.

Common mistakes

• Not recording dose-change dates. Without them, you can't attribute results or side effects to anything.
• Weighing daily and panicking. Daily weight is noisy; trust the weekly trend.
• Skipping the side-effect log. Side effects are data that inform whether to hold a dose longer.
• Forgetting inventory. A weekly protocol means a vial has to last — track stock so a missed reorder doesn't break your cadence.

The bottom line

A GLP-1 protocol is a slow, titrated experiment, and experiments need records. Log each weekly dose with its date and site, weigh in consistently, note side effects against dose changes, and review the trend — not the day. Do that and you'll know whether the protocol is working, when to expect a plateau, and what to discuss with your provider.
