No dosing guides." canonical: "https://peptyn.orlyn.ai/articles" last-updated: "2026-08-16" --- # Writing about the *record*, not the dose. *Educational writing on keeping a protocol record: the fields that matter, the vocabulary, the paperwork, and what the published literature says. No dosing guides.* Educational · Not medical advice · 18+ Almost everything written in this space answers a record-keeping question with dose arithmetic. These articles do not. There are no dosing guides here, no titration schedules, no unit conversions and no reconstitution maths, because what to inject and how much belongs to the person who prescribed it and to the label it was prescribed under. What is left is the part nobody writes: what to write down, what the words mean, what the published sources actually say, and what a record can and cannot answer later. 14 articles · every factual claim linked to a primary source ## Keeping the record The fields that earn their place, and what each one answers months later. - [The GLP-1 tracking spreadsheet: eight fields that matter](https://peptyn.orlyn.ai/articles/glp1-tracker-spreadsheet) The eight columns worth keeping, what each one answers months later, and the three moments a spreadsheet stops being the right tool. 8 min read - [Did I take my meds today?](https://peptyn.orlyn.ai/articles/did-i-already-take-my-shot) Why the memory fails for everyone, what the poison-centre data actually shows, and which checks do not hold up. 6 min read - [What a six-month injection site log shows](https://peptyn.orlyn.ai/articles/glp1-injection-site-rotation-log) What the rotation research really found, which drug it was found in, and what your own site history adds that a chart cannot. 6 min read - [The 28-day rule, and when it applies](https://peptyn.orlyn.ai/articles/28-day-rule-glp1-vial) Where the number comes from in USP 797, why most GLP-1 labels set a different one, and which date only you can record. 10 min read - [Your lot number, and how to check it](https://peptyn.orlyn.ai/articles/glp1-recall-lot-number) Where the code lives on a pen, vial and carton, how to search FDA enforcement records, and which channel takes which report. 11 min read ## Understanding the vocabulary The words and the regulatory status behind them, every claim traced to a primary source. - [The glossary that will not do your math](https://peptyn.orlyn.ai/articles/peptide-glossary) Plain definitions from lyophilized to 503A, with sources.
