Compounded Tirzepatide Tracker
Engineered for compounded tirzepatide vials. Convert mg to syringe units across 10 mg/mL, 20 mg/mL, and custom concentrations, model 5-day dual-agonist half-life curves, and forecast reorder dates on iOS.
GLPme is a dedicated tracking and calculation app built for compounded tirzepatide patients. Managing multi-dose tirzepatide vials (10 mg/mL, 20 mg/mL, and custom peptide reconstitution) with insulin syringes requires exact concentration math. GLPme translates prescribed milligrams into syringe units, graphs your 5-day half-life decay, tracks injection site rotation, and monitors weight loss progress without subscriptions.
Key takeaways
- Precision syringe conversion: maps compounded tirzepatide mg to syringe units across 10 mg/mL, 20 mg/mL, and custom vials.
- Visual confirmation prevents concentration mix-ups between starting doses (2.5 mg) and maintenance doses (15 mg).
- Tirzepatide 5-day half-life graph reveals active blood levels and predicts end-of-week hunger return.
- Vial supply forecasting warns you when your vial is running low to prevent missed injection weeks.
- 100% on-device private logging on iOS: zero accounts, zero trackers, zero data sharing.
Compounded tirzepatide: The syringe calculation challenge
Compounded tirzepatide is dispensed in diverse concentrations — most commonly 10 mg/mL, 20 mg/mL, or concentrated blends containing vitamin B12 or glycine. Because tirzepatide doses range widely from 2.5 mg up to 15 mg, drawing medication with a U-100 insulin syringe requires flawless arithmetic.
A mistake of 10 syringe units can mean under-dosing by half or accidentally doubling a dose, resulting in severe gastrointestinal distress. GLPme provides a failsafe visual confirmation: simply select your vial strength and your prescribed dose, and the app shows the exact syringe volume to draw.
Syringe unit conversion matrix
Here is how common compounded tirzepatide doses translate on a standard U-100 syringe:
| Dose | 10 mg/mL Vial | 20 mg/mL Vial | 25 mg/mL Vial |
|---|---|---|---|
| 2.5 mg | 25 units (0.25 mL) | 12.5 units (0.125 mL) | 10 units (0.10 mL) |
| 5.0 mg | 50 units (0.50 mL) | 25 units (0.25 mL) | 20 units (0.20 mL) |
| 7.5 mg | 75 units (0.75 mL) | 37.5 units (0.375 mL) | 30 units (0.30 mL) |
| 10.0 mg | 100 units (1.00 mL) | 50 units (0.50 mL) | 40 units (0.40 mL) |
| 12.5 mg | 125 units (Requires 2 syringes) | 62.5 units (0.625 mL) | 50 units (0.50 mL) |
| 15.0 mg | 150 units (Requires 2 syringes) | 75 units (0.75 mL) | 60 units (0.60 mL) |

Modeling tirzepatide's 5-day half-life curve
Tirzepatide has an elimination half-life of 5 days (120 hours). At steady state, weekly injections produce a predictable wave: concentration peaks at 24 to 48 hours post-injection, and decays by roughly 60% by Day 7. GLPme graphs this pharmacokinetic reality so you can anticipate appetite shifts and coordinate your injection timing with your weekly schedule.
Vial supply and reorder forecasting
Compounded telehealth pharmacies frequently require 7 to 14 business days to compound, quality-test, and ship a replacement vial. GLPme's vial tracker calculates your remaining volume based on logged doses and alerts you 10 days before your vial runs dry, ensuring you never face an unexpected supply gap.
