Frequently asked questions
What is a peptide cycle tracker?
A peptide cycle tracker counts the days you've been on a compound, shows progress toward your cycle end date, and helps you plan washouts between cycles.
How long should a typical cycle be?
It depends on the compound and your protocol. Common research cycles range from 4–12 weeks. The tracker accepts any cycle length in days.
Can I track multiple cycles at once?
Yes. Every compound has its own cycle bar and end date. The dashboard shows all of them on one screen.
What happens when a cycle ends?
The progress bar fills to 100%. You can extend the cycle or archive the compound and start a new one.
