PeptCycle dashboard — daily progress and doses
Protocols

Every dose, planned in advance.

Describe the protocol once — frequency, time, injection sites, "on / off" cycling — and PeptCycle generates the schedule ahead. All you do is log.

Protocols — cards with cycles and progress
Calendar

One tap. Logged.

Taken, skipped or missed — every dose is logged in a second, even from the lock screen or a widget. Future dates cannot be logged ahead of time, so the history stays honest.

Progress

See where you are heading.

A weight chart with your goal and your protocol periods drawn on it. Streaks, adherence in percent, optional Apple Health — and a PDF report ready to review with your doctor.

What lipohypertrophy is, why injection guidance insists on rotating sites, and what the FITTER recommendations say about spacing, needle reuse and inspection.
