Your 24/7 Biohacking Expert
Finally.
Finally, you can stop Googling your symptoms and getting advice written for a man's body.
Finally, you can stop pushing through workouts on empty and wondering why nothing's working.
Finally, you can stop feeling like a stranger in your own skin.
Bestie will...
- Answer any question about your body — instantly, personally, accurately
- Tell you exactly what to eat, when, and why — based on your cycle phase
- Sync your workouts to your hormones so you stop burning out and start burning fat
- Explain why you feel the way you feel — and what to actually do about it
- Be there at 2am when you're spiralling about your skin, your weight, your energy
Instead of Googling for hours, booking expensive consultations, or buying supplements you don't need — you can just ask Bestie.
DOES THIS SOUND FAMILIAR?
“I eat well and work out but I can't shift the weight. What am I doing wrong?”
“My skin breaks out every month in the same spot. Is that hormonal?”
“I'm at a restaurant — which option on this menu is actually good for my hormones?”
“I made eggs and avocado for breakfast. How do I make this more hormone-balancing?”
“Why am I SO tired on Day 22 even when I sleep 8 hours?”
“I've been tracking my cycle for years but I still don't know what to do with the information.”
Then the doubt creeps in...
"I should be further along by now."
"What if my body is just broken?"
"What if I'm doing everything right and it still won't work for me?"
Every woman hits this point.
You are not alone.
Life doesn't stop for your hormones. You're at a work dinner and you don't know what to order. You're at the gym and you don't know if you should push or rest. You're standing in your kitchen at 7am trying to make a healthy breakfast and you don't know if it's actually helping or hurting.
That's exactly what Bestie is for.
IS THIS YOU?
You know you eat "healthy" but you still feel bloated, tired, and stuck
You track your cycle but have no idea what to actually do with that information
You've tried every diet and the weight always comes back
You push through workouts on your worst days and wonder why you're not seeing results
You Google your symptoms and get advice that was clearly written for a man's body
Your skin breaks out, your mood crashes, your energy disappears — and no one can explain why
You spend money on supplements, programs, and consultations — but nothing sticks
You feel like your body is working against you
You want to finally understand what's actually going on inside — and what to do about it
The Simple Truth
The problem was never you.
Every program you've ever tried was designed for a male body. They don't account for the female 28-day hormonal cycle — the rhythm that controls your hunger, your fat-burning, your energy, your mood, and your metabolism.
You weren't failing the programs. The programs were failing you.

Hi, I'm Aggie.
I've been exactly where you are.
I spent years fighting my body — over-exercising, under-eating, wondering why nothing worked no matter how hard I tried. Then I discovered biohacking and cycle syncing, and everything changed.
I wrote a book about it. I built a supplement line around it. And now I've built Bestie so you can have me — and everything I know — in your pocket, every single day.
Ask Aggie AI is trained on years of research, my own healing journey, and thousands of questions women have asked me. It's not generic advice. It's your answer, for your body, on your cycle day.
