GLP-1

GLP-1 guides, and the free tracker that goes with them

59 pages on the weekly shot and the daily pill: the trials behind them, what to log, what to expect, and what to do when a dose goes missing.

Semaglutide, tirzepatide and the newer pills are peptides, or act on the same receptor, and the people taking them have the same problem as anyone on a weekly injection: which dose was it, when, where did it go in, and what happened after. These pages cover the practical questions, the side effects by week, every medication by name, and how the free Peptide AI log fits around a prescription.

None of it is medical advice. Your prescriber sets the dose. The app keeps the record.
