Your hormones are not a problem to solve.
Estrogen, progesterone, and the rhythm between them shape how you sleep, train, think, and feel. Learning that rhythm is not about controlling your body. It is about finally having language for what you have always noticed.

The four phases, briefly
Menstrual, follicular, ovulatory, luteal. Each one shifts your energy availability, your appetite, your recovery capacity, and your tolerance for stress. None of them is the good phase.

Bars built on all of this.
Four protein bars, one for each phase of your cycle. First batch ships this fall.
