Free date tool
Cycle Date Mapper
Turn an active phase and break phase already chosen with a qualified clinician into calendar dates. This tool does not suggest whether to cycle anything or how long either phase should be.
Enter the start date and both clinician-provided phase lengths to build the date map.
What this mapper does
The active phase begins on the date you enter and lasts for the whole number of weeks provided. If a break phase is included, it begins the following day and the mapper marks when the next phase would start.
It performs calendar arithmetic only. It does not choose phase lengths, evaluate a compound, or determine whether a break is appropriate.

Frequently asked questions
What does the cycle date mapper do?
It converts a start date plus whole-week active and break phase lengths into calendar dates. It does not choose those lengths or decide whether a cycle is appropriate.
Why are there no default cycle lengths?
A default could look like a recommendation even though appropriate timing is specific to the person, substance, and clinical plan. Enter only lengths already established with a qualified clinician.
How are the dates calculated?
The active phase starts on the chosen date and runs for the whole number of weeks entered. If a break is included, it starts the following day and the next phase is marked after that break ends.
Can I map a plan with no break phase?
Yes. Enter 0 for the break phase and the mapper will show only the active phase. That is calendar behavior, not a statement that a break is unnecessary.
Does this tool recommend cycling a peptide?
No. It performs date arithmetic only and does not recommend starting, stopping, or cycling any substance. Those decisions belong with a qualified clinician.
