Semaglutide tracker
for iPhone.
Semaglutide protocols are deceptively simple — one weekly shot that sits in plasma for the better part of a week — and that long half-life is exactly why they get untracked. You forget what week you're on. You guess the units. You miss the appetite drift. Peptide Protocol holds the schedule, the math, and the symptom log in one place, so the only thing you have to do is the dose itself.

| Class | GLP-1 receptor agonist |
|---|---|
| Brand names | Ozempic (T2D), Wegovy (chronic weight management), Rybelsus (oral) — all manufactured by Novo Nordisk |
| Plasma half-life | ~7 days |
| Typical cadence | Once weekly, subcutaneous |
| Typical dose range | 0.25 mg → 0.5 mg → 1.0 mg → 1.7 mg → 2.4 mg, escalating every 4 weeks per FDA label |
| Common reconstitution | 5 mg vial + 2.0 mL bacteriostatic water → 2.5 mg/mL → 0.10 mL = 0.25 mg dose |
| Insulin syringe | U-100 most common (10 units = 0.10 mL = 0.25 mg at 2.5 mg/mL) |
| Common stack pairings | Cagrilintide ("CagriSema" pattern); some users transition to Tirzepatide for stronger appetite suppression |
| Common side-effect pattern | Nausea and slow gastric emptying during step-up weeks; usually settles after 5–10 days |

Built around Semaglutide protocols
Three things the app does that the manufacturer's pen, a calendar, or a spreadsheet won't.
Knows your step-up week
Lay out the 0.25 → 2.4 mg ladder with 4-week holds. The app advances you on the scheduled date and updates the dose calculator output in the same gesture — no mental arithmetic, no flipping between apps.
Vial-aware reconstitution math
3 mg, 5 mg, 10 mg vials supported with sensible BAC water defaults. Pick what you actually used, and the unit count for U-100 / U-50 / U-30 syringes appears instantly. Re-runs whenever the dose changes.
Weight + symptom timeline
Daily check-ins capture appetite, weight, energy, sleep. Insights overlays weight against the dose timeline so you can read off when each step actually started moving the chart, and where the GI weeks landed.

Semaglutide tracking — common questions
Does Peptide Protocol have a Semaglutide preset?
Yes. The reconstitution calculator ships with Semaglutide presets covering common research-vial strengths (3 mg, 5 mg, 10 mg). Choose the vial mass and BAC water volume you used, set your target dose, and the app outputs the unit count for a U-100, U-50, or U-30 insulin syringe.
How does Peptide Protocol handle the 0.25 → 2.4 mg ladder?
Add the five escalation steps to your protocol once: 0.25 mg → 0.5 mg → 1.0 mg → 1.7 mg → 2.4 mg, each held for 4 weeks per FDA label. The app increments the target dose on the scheduled date and the calculator follows automatically — your draw is always correct for the week you're on.
Can I track Semaglutide weight loss next to my dose log?
Yes. The Insights tab charts weight against your dose timeline, so you can see how each escalation step landed. Daily check-ins capture appetite, energy, sleep, and free-text notes — useful for spotting GI discomfort patterns common in the first weeks of each step-up.
