Biohacking
The self-quantified, data-to-action human.
Body composition, the GLP-1 course already documented here, and the fracture recovery that interrupted both now sit in one pillar instead of loose under Training. The filter is the one the training charts already use: a change counts when the logged numbers move.

What This Pillar Tracks
Four running threads, all fed by the same logs
Body Composition
Weekly circumferences run through a linear regression model for body fat and lean mass, because there is no DEXA within reach. Imperfect, consistent, and the only reason I know roughly 4 kg of estimated lean mass left alongside the fat.
Read the muscle-preservation log → OngoingGLP-1 Protocol
Tirzepatide, then semaglutide, then back to tirzepatide on the Japanese label. The full dosing history, timeline and side-effect record lives on the public GLP-1 hub — this pillar links to it rather than restating it.
Open the GLP-1 hub → RehabRecovery & Repair
A right subtrochanteric femur fracture on 21 April 2026, six weeks non-weight-bearing, and a load progression decided by radiographs rather than the calendar. Told through what could actually be measured.
Read the recovery data → Kept or droppedProtocols on Trial
Things tried, measured, and then kept or dropped on the evidence of my own log. The supplement stack is currently paused, which is the honest state of it rather than a recommendation.

GLP-1 While Training for Endurance: The Muscle-Preservation Question
What the body-comp log shows about lean mass across a semaglutide course, the protein and lifting protocol run alongside it, and where the data refuses to give a clean answer.
Read → RecoveryRebuilding a Femur on Data
Six weeks non-weight-bearing, a callus on a Week 6 X-ray, and a first jog four weeks ahead of the projection. Which metrics were decision-useful and which were just noise.

Dose escalation, a paused supplement stack, and a few habits I was sure about. What my own log said, and nothing about what yours will say.

Every other data-backed section on this site — the commit lanes, the training load, the weight and body-fat charts — runs on real logged data, not narrative. This pillar pulls from the same body-composition log already powering the homepage charts. Nothing here is backfilled or estimated, and a protocol that did not move the numbers gets written up as a protocol that did not move the numbers.
This is a personal log from a sample size of one, written by someone who is not a clinician. Nothing on these pages is medical advice. The GLP-1 course runs under a prescribing physician; the fracture rehab runs under a surgeon and a physiotherapist.
