Not medical advice. The Journal of Biohacking reports published research and teaching models. Nothing on this page is medical advice, a diagnosis, or a recommendation to use any compound, product, or therapy. Where a dose appears, it is a figure reported in a cited study or by its sponsor, not an instruction. Editorial position on dosing.

Go inside the cell. Go beyond baseline.

You are not one body — you are a federation of roughly 37 trillion cells, each one running power plants, factories, recycling crews, and a library of instructions. Tap any part of the cell to see what it does, what wears it down, and what published studies have reported. Grades label that evidence. They are not instructions.

~37 trillioncells in an adult human body — an estimate from cell counts by tissue type (Bianconi et al., 2013)
~100 trillionmitochondria across the body, inherited almost entirely from your mother
Secondsyour stored ATP would last without constant recycling — cells remake it continuously, roughly your body weight in ATP per day
120 daysaverage lifespan of a red blood cell — while many neurons last your whole life
The JoB premise: most medicine aims to return you to baseline. This explorer is built for the next question — once you can see the machinery, what does it take to run it better than baseline?

The living cell, part by part

Select an organelle — a “little organ” inside the cell — on the diagram or in the list. The panel beside it explains the job in plain language, one fact worth remembering, and the levers with the strongest evidence behind them.

The Energy Lab — your day, run through a cell

Move the sliders to a rough version of your last 24 hours. The model is deliberately simple and illustrative — not a diagnosis — but the direction of each effect is the direction the research points: sleep, movement, food, and stress load change how well your mitochondria make energy and how much oxidative “exhaust” they produce.

Your last 24 hours

Drag each slider, or load a preset day.

Bleeding edge: beyond the cell you were born with

The frontier past CRISPR headlines — what serious labs and clinics are actually attempting now, graded honestly. Real practice means it exists outside a press release; early signal means promising but unproven in humans; speculative means the idea is coherent but the evidence is not there yet. Nothing here is a recommendation.

Check your cell IQ

Three questions. No grades sent anywhere — just you versus the diagram you just explored.
