Around eight million Americans are on a GLP-1 right now, and the number is heading toward twice that. On the medical question there is not much argument left: the drug works.
What does not work is everything arranged around it. You get a prescription, a pen, and a pharmacist who has already explained this to six other people that hour. You get a manufacturer app that tells you to live your best life. Then it is you, a needle, and a search box at one in the morning.
The questions nobody's app answers
Not the ones a marketing page finds convenient — the ones that actually get typed into a phone in the dark:
- Is this fatigue the semaglutide, or is it the deficit?
- The sulfur burps started at week three. Is that normal?
- Can I rotate injection sites within the same week?
- Six pounds this week — was that water or was that fat?
- Am I losing too much muscle to be doing this well?
A notebook, not a coach
Lean Protocol is the notebook for those questions. It is not a coaching app; there is no cheerful line congratulating you on a good week. The home screen looks like a spec sheet, because that is what it is.
Log every injection — date, dose, site, and whatever showed up afterwards. Log a weight when you feel like it, and the trend does the smoothing so a bad Tuesday morning is not an event. Tag the food that did not sit right, and after a few weeks the tolerance map has built itself out of your own weeks rather than a stranger's forum post.
And it keeps protein against a target and asks whether you lifted, because the quiet failure mode of these drugs is dropping lean mass alongside the fat — a considerable share of the total, if nothing is done about it. The scale reads as success either way, which is precisely the problem.
How this is paid for
We do not sell your data to a pharmaceutical company. We take no supplement money and no clinic affiliate fee, and there is no influencer arrangement behind any of this.
The web notebook is free and stays free, with no account and no card. Membership is $14.99 a month or $99.99 a year, seven days free first, and buys sync and the iOS app when it ships. One tier, no upsell. That is the entire business model, stated plainly — and it is the reason we have nothing to gain from knowing what is in your log.
GLP-1s changed what is possible. This is the boring infrastructure that makes the year afterwards survivable.
