Your body is changing.
Nobody explained why.
KRUUSH puts perimenopause in one place. The research. The tracking. The doctor report. So you stop guessing and stop feeling alone.
72 symptoms from 8 peer-reviewed sources. 3 minutes. Zero sign-up required.
Compiled from 8 peer-reviewed sources including Aras et al. (2025), The Lancet, Cleveland Clinic, and Harvard Health.
Your data matters. Every answer you share (completely voluntary, totally anonymous) helps build a perimenopause dataset created by women, for women. Nothing like it exists yet. No names. No emails. Just your truth, helping future women get better answers. How we protect your data →
Not medical advice. KRUUSH is a wellness tracking tool. Always consult your healthcare provider.
Here's something nobody told you: testosterone isn't just a "male hormone." Your ovaries make it. You need it. When it drops during perimenopause, menopause, or just life, it affects your energy, your mood, your libido, your brain, your bones.1
Yet. As of 2022, 33 FDA approved testosterone therapies existed in this country. Every single one approved for men.2
Not because the research isn't there. It is.
Not because it doesn't work in women. It does.3
But because testosterone is a generic drug. Nobody can patent it, so nobody's rushing to fund the trials that would get it approved for us.4
Right now, if your doctor wants to prescribe it, she has to give you a men's formula at one tenth the dose and call it "off label." Or a compounded version with no standardized safety data. That's where we are.5
For the record: estrogen is FDA approved for women's menopausal symptoms. This gap is specific to testosterone. We're not starting from zero. We're being left behind.
Your daughter deserves better than the same silence you inherited. So do you.

From early testers
"Finally something that helped me explain this to my doctor. I walked in with 30 days of data and she actually listened. First time in two years."
Sarah, 48. Early perimenopause.
"I thought I was losing my mind. Turns out my brain fog peaks every time my sleep tanks. I never would have connected those dots without tracking."
Michelle, 44. Pre perimenopause.
"My partner and I took the quiz together. We've been married 22 years and it started a conversation we should have had a decade ago."
Dana, 51. Late perimenopause.
