Protocol Tracking
Why a Dosing Calendar Is Not Enough for Complex Protocols
What a protocol dose log captures that a calendar cannot, why missed doses are invisible in calendar-based tracking, how multi-compound protocols break calendar-based systems, and what a complete protocol timeline looks like.

Why a dosing calendar is not enough
A calendar shows you when to inject. It does not show you what you injected, whether you actually injected on that day, how many units you drew, which site you used, or how you felt afterward. A calendar is a schedule; a protocol log is a record.
For simple single-compound protocols at a flat dose, a calendar is probably sufficient. But as soon as two variables change — compound added, dose escalated, vial changed — a calendar starts failing. It doesn't capture the actual history; it only shows the intended history.
What a protocol log captures that a calendar can't
| Data point | Calendar | Protocol log |
|---|---|---|
| Scheduled injection date | ✓ | ✓ |
| Actual injection date/time | ✗ | ✓ |
| Dose in mg (not just compound name) | ✗ | ✓ |
| Units drawn (auditable calculation) | ✗ | ✓ |
| Injection site used | ✗ | ✓ |
| Site rotation history | ✗ | ✓ |
| Vial/reconstitution batch | ✗ | ✓ |
| Side effect notes | Limited | ✓ |
| Missed doses (visible as gaps) | No — missed dose looks the same as injected day | ✓ — visible gap in log |
| Escalation date history | Only if manually annotated | ✓ — from actual dose entries |
The missed dose problem
A calendar with a weekly tirzepatide reminder marked doesn't distinguish between "injected Thursday" and "didn't inject Thursday." Four weeks later, when you're trying to evaluate whether steady state has been achieved, the distinction matters enormously. A protocol log captures actual injection dates — the blank is a missed dose, not a day that was already accounted for.
Multi-compound protocol calendars: where they break completely
Consider a protocol with:
- Tirzepatide: weekly, dose escalating every 4 weeks
- BPC-157: daily, once or twice daily
- TB-500: twice weekly during loading, weekly during maintenance
A shared calendar requires a separate entry type for each compound and each dose level. When the TB-500 loading phase ends and maintenance begins, the calendar needs to be restructured. When tirzepatide escalates, the dose entry needs updating. A missed BPC-157 dose on Tuesday looks identical to an injection day on the calendar.
The compound-tracking problem grows geometrically, not linearly. Three compounds with different schedules and dose changes aren't three times harder to track than one — they're nine times harder (each compound's state interacts with the others). A calendar wasn't designed for this.
What a protocol timeline looks like in My Pep Calc
My Pep Calc renders your protocol as a timeline: each compound has its own log of actual doses, with dates, amounts, sites, and notes. The half-life chart translates that log into a visual active concentration curve — so you can see when BPC-157 is active (daily pulses), when TB-500 is accumulating (loading curve), and when tirzepatide has reached steady state, all on the same timeline from your actual injected doses.
This is the difference between a schedule (what you intended) and a record (what happened). Clinical decisions — escalation, dosing holds, provider visits — should be made from the record, not the schedule.
Frequently asked questions
- Can I just use a calendar to track my peptide protocol?
- A calendar shows scheduled injection days but can't distinguish between injected and missed doses, doesn't capture the dose amount at each step, doesn't track injection site rotation, and doesn't store the escalation history your provider needs. For single-compound flat-dose protocols, a calendar is workable. For multi-compound or escalating protocols, a dedicated dose log is more reliable.
- How do I know if I've missed a dose?
- If you're relying on memory or a calendar, a missed dose is often only discovered when you try to reconstruct your history. A dose log makes missed doses immediately visible as a gap — there's no entry for that date. This matters pharmacokinetically: for weekly GLP-1s, a missed dose changes the timeline to steady state and may affect how you tolerate the next dose.
- What is the best app to track peptide injections?
- My Pep Calc is purpose-built for multi-compound peptide and GLP-1 protocols: dose logging with amounts and injection sites, reconstitution calculator integration, half-life charts from actual logged doses, and escalation history your provider can review. Generic apps (notes, calendars, habit trackers) work for simple protocols but lack the dose-specific and pharmacokinetic features needed for complex stacks.
- Why does injection site need to be logged?
- Repeated injections at the same site cause lipohypertrophy — fatty tissue buildup that reduces absorption by 25–40%. Logging the site per injection enables rotation tracking: you can see which sites have been used recently and avoid overusing any single site. For daily BPC-157, this matters significantly because there's no accumulation buffer — impaired absorption directly reduces active levels.
