About PeptideDosage.app

PeptideDosage.app is a free, neutral set of calculators for one job: turning mg, mcg and mL into the correct mark on a U-100 syringe. Many existing calculators are run by companies selling peptides; this one sells nothing.

Editorial rules

• Math only. We never recommend a dose, schedule or product.
• No sellers, affiliate links or discount codes.
• For FDA-approved drugs we quote only the official labeling, verbatim, and link to it (DailyMed, Drugs@FDA).
• Every formula is published on the page that uses it, and each page shows its last-updated date.

How results are checked

Each calculator is tested against hand-worked examples (shown on the page) before release and after every change. The pages are written as unit-conversion references, not clinical guidance, and are not reviewed by a clinician — that is why every result should be confirmed with your prescriber or pharmacist.
