A peptide cycle tracker that remembers the off weeks too.
Many peptide routines run in phases: a stretch on, a break, then a restart. Peptide Protocol keeps each protocol's start date, schedule and dose history, marks breaks and cycle ends on the calendar, and lets you pause with a return date so the routine resumes on the day you chose rather than the day you remember.
Download Peptide Protocol — FreeWhat is a peptide cycle tracker?
A peptide cycle tracker records when a protocol is running, when it is on a break and when it restarts. In Peptide Protocol each protocol has its own start date and schedule; the calendar and timeline mark done, scheduled, missed, skipped and paused doses alongside breaks and cycle ends; and a paused protocol auto-resumes on the return date you set. Cycle and break lengths come from your own plan or clinician; the app records them and does not choose them.
What Peptide Protocol tracks
| Start date and schedule | Each protocol keeps its own start date, dose, cadence and schedule, entered once when you build it. |
|---|---|
| Calendar and timeline | See done, scheduled, due, missed, skipped and paused doses by day, with cycle ends and break days marked. |
| Pause with a return date | Pause a protocol for an off-period and it auto-resumes on the date you picked. |
| Cycles side by side | Protocols run independently, so one compound can be on a break while another continues. |
| Phase history | Dose log, check-ins and the weekly report keep every on- and off-period on one timeline for later review. |

How to use it
- 1
Build the protocol
Enter the compound, dose, cadence and start date from your own plan or prescription.
- 2
Log doses during the run
Each logged dose becomes part of the record of that phase; missed and skipped days stay visible.
- 3
Pause for the break
When your plan calls for an off-period, pause the protocol and set the return date.
- 4
Review before restarting
Compare adherence, check-ins and side-effect patterns between phases in Insights and the weekly report.

Peptide cycle tracker — common questions
Can I track peptide cycles with on and off periods?
Yes. Build each protocol with its start date and schedule, then pause it with a return date when the break starts. The protocol auto-resumes on that date, and the calendar shows paused days, break days and cycle ends next to the doses you logged.
Does the app tell me how long a peptide cycle should be?
No. Cycle length, break length and dose come from your own plan or your clinician. Peptide Protocol records and schedules what you enter; it does not recommend, calculate or adjust a regimen.
Can I run more than one cycle at the same time?
Yes. Protocols run side by side, each with its own compound, dose, cadence, inventory and injection-site rotation, so one can be on a break while the others continue on the Today screen.
