14 lb down in 19 weeks of retatrutide.

A guided read

What moved, and when?

Each line is the typical reading of each week from one device. The lane on top is the drug, with a pin at every dose step. Pick a card and its measure stays lit, with the typical week before the first dose and the latest three weeks drawn as level lines; pick it again and the drawing is plain.

Every result, read and explained.

Drop in a lab PDF and every value is read, named the same way everywhere, and placed on its own line of history. You never retype a number. Then the panel reads itself: which results crossed a line, which are still outside, what each one is, and what you were taking when it was drawn. Every claim is arithmetic you can check against the drawing.

A guided read

What changed in this panel?

Every result as a share of its own normal range, so the tests can be read against each other: the green band is normal on every row, and 120% is a fifth past the top. Pick a line in the card to light its row.

Every night, read under its own stages.

The CPAP by the bed and the watch on your wrist record the same night from two sides. Selfsense lays oxygen, pulse and breathing under the night's stages and reads it: when you reached dreaming sleep, when you woke, what oxygen did while you did. Pick a card and the night marks the minutes it was read from.

A guided read

What happened, and why?

Oxygen, pulse and breathing under the night's own stages. Each line is a fifteen-minute average; the dashed one on oxygen is 90%. Pick a card and the night marks the minutes it was read from; pick it again and the night is plain.

The week, one row per thing.

Sleep, the mask, steps, pulse, weight and the doses you ticked, a square a day, each against your own usual. Not a score. The usual is the middle of your last thirty days, so the only thing a square can tell you is whether today was like you.

A Canadian AI that has read every line.

Ask what changed and why. The coach has read every result, every date, every dose and every night, and answers in Canada: nothing you tell it trains a model, and every time it is shown your record, that is written down for you to read. A coach, not a doctor. It says when a question belongs to your prescriber.

A sample exchange · invented record

“ALT has been above range three draws running. What else changed over those months?”

CoachThree things sit over those draws. The prescription restarted Sep 3, a week before the second one. September has 14 evenings with alcohol logged against 3 in August. And the two heaviest lifting weeks of the year fell in the days before the Oct 27 draw; ALT rises after hard training in a lot of people. It was 31 before any of them. I can't tell which from here. A liver enzyme that stays up three draws is one to take to your prescriber, and a repeat after a dry fortnight with no lifting would separate the alcohol and the training from the rest.

Ask next
Every ALT draw since 2023: what changed?When should I draw it again?Is it worth raising with my doctor?

Disclosed to the coach: 3 lab draws, 2 protocols, 61 days of alcohol and workouts, 1 note · logged Nov 5, 7:12 am
