Editorial policy

Which sources come first

We start with the most official sources: the FDA’s current prescribing information, medication guides, and the drug maker’s instructions for use. Next come FDA safety notices and regulatory pages, which we use for warnings, the rules on compounded (pharmacy-made) medicines, and reports of side effects and other problems. For medicines that are still being studied, we use published trial results, ClinicalTrials.gov records, and trial reports from the companies running the trials. Standards from ISO and USP (groups that publish official standards) back up our definitions for devices and for sterile compounding. We only use secondhand sources when no original source is available, and when we do, we say what that limits.

Every fact in the site’s data is tied to one or more sources. For each source we store the title, publisher, web address, the date we accessed it, and its revision when the source gives one. Each page’s Sources section is built from those same records, so anyone can check it. We never use a source to back up a bigger claim than the source actually makes.

How facts and pages are updated

A label change, a new pen or vial, an FDA notice, new trial results, or a change to a device starts a review of that fact and every page that shows it. We normally review our sources every three months, and sooner if there is an important safety or regulatory change. Every update keeps the page educational: we can correct the math without turning it into dosing advice.

Corrections and reports from readers

Correction contact: hello@dosepep.com. Someone reads this inbox. A helpful report gives the page address, quotes the exact claim or table cell, explains what you think is wrong, and links to an original source if you can. When we accept a correction, we make the fix in the sourced data or the page text, check it on the finished site, and include it in the next review. If we don’t accept a report, we keep a note of why, so the decision can be checked later.

Medical review and help from AI

Ashley Alexis, ND reviewed the site’s calculators, dose pages, syringe guides and pen pages on September 30, 2026. A page she has reviewed says “Medically reviewed by” with the review date. Pages marked “Medical review in progress” are still being reviewed by the doctor and haven’t been signed off yet. The writing on this site was drafted with help from AI. We do not treat anything AI produced as a source or as medical judgment. The review checked the numbers, that each fact is credited to the right source, that each product is kept separate from the others, that medicines still being studied are clearly described that way, and whether any sentence could be read as an instruction.

What we cover, and how we write

Dose schedules on this site are shown as what a label or a clinical trial says, for background. We explain formulas and what device instructions say. We do not recommend a dose, choose a product, help anyone get or buy a medicine, or replace your prescriber or pharmacist. Retatrutide pages always make clear that it is still being studied and not FDA-approved. If we ever have a business relationship with a company, we must say so right next to the related link, and it must be reviewed to make sure it follows the regulations.
