BUILT FOR GLP-1 USERS

The dose tracker built for
Semaglutide, Tirzepatide, and Retatrutide

Weekly dosing. Multi-week titration. Side-effect curves you can’t fake. Most habit trackers weren’t built for this. DoseCraft was.

Why GLP-1 needs its own tracker

Weekly dosing breaks habit-tracker math. Most apps assume daily cadence. GLP-1 protocols are weekly with multi-week titration steps. The compliance picture only works when the tracker thinks in weeks, not days.

Titration is the whole game. Dose-escalation steps can bring nausea and other side effects. Logging symptoms alongside your prescribed dose gives your clinician a clearer picture when you discuss whether to continue, pause, or adjust treatment. Don’t change your dose without clinical guidance.

Plasma concentration matters. With a 5–7 day half-life, drug levels change gradually. A half-life chart estimates that change; it cannot determine your therapeutic threshold. Follow your medication’s instructions and ask your clinician about missed doses.

The compounds, compared

Same family, different receptor profiles. Pick by goal, evidence depth, and tolerability.

Semaglutide

GLP-1

Single-receptor GLP-1 agonist. The most-prescribed, best-evidenced.

Receptor
GLP-1 only
Half-life
~7 days
Cadence
Weekly subcutaneous
Typical loss
~15% body weight @ 68 weeks (STEP-1 trial)
Full profile

Tirzepatide

GLP-1

Dual GLP-1 + GIP agonist. Stronger weight-loss data, comparable tolerability.

Receptor
GLP-1 + GIP (dual)
Half-life
~5 days
Cadence
Weekly subcutaneous
Typical loss
~20% body weight @ 72 weeks (SURMOUNT-5 head-to-head)
Full profile

Retatrutide

GLP-1

Triple GLP-1 + GIP + glucagon agonist. Phase III, not yet FDA-approved.

Receptor
GLP-1 + GIP + Glucagon (triple)
Half-life
~6 days
Cadence
Weekly subcutaneous
Typical loss
~24% body weight @ 48 weeks (Phase II data)
Full profile

What you get

The features that actually move the needle when you’re titrating a GLP-1.

Titration scheduling

Record your prescribed dose and set weekly reminders. Many GLP-1 schedules increase doses in multi-week steps; your clinician guides each change.

Side-effect log

Nausea, GI distress, fatigue, injection-site reactions — log severity 1–10 against the dose schedule. Spot which step is intolerable before it derails the cycle.

Weight + body comp trend

Track weight and body-fat % over time. Review your weight trend alongside your dose log to discuss changes with your clinician.

Half-life-aware reminders

Explore estimated concentration over time and set weekly dose reminders. The chart is a model, not a measured drug level or a guide to changing your dose.

Reconstitution math

5 mg vial + 2 mL bac water → 250 mcg per 0.1 mL → 10 units on a U-100. Calculator runs the math, syringe visual confirms the draw line.

Side-effect playbook

Coach explains research on common GLP-1 side effects and helps you prepare questions for your clinician. Dose changes need clinical guidance.

FROM DOSECRAFT COACH

Semaglutide and Tirzepatide are weekly subcutaneous incretin agonists, but they target different receptors. Trials show differences in average weight loss; side effects, access, and cost also matter. Both require gradual dose escalation under clinical supervision. Coach helps you explore the research and prepare questions for your clinician.
