Fact

Self-experimentation done right

Real biohackers run controlled experiments on themselves: change ONE variable at a time, measure for 4-6 weeks, track outcomes objectively. Changing five things at once and feeling better tells you nothing about which one worked. Pick a clear metric (sleep score / HRV / fasting glucose / mood rating), commit to one intervention, and let the data decide.
