Free, no-sign-up microdose calculators for people who want smoother GLP-1 dosing.
GLP1Microdose.com is a free educational resource for split-dose / microdose protocols of GLP-1 receptor agonists (semaglutide, tirzepatide, retatrutide). We provide a calculator, plasma level plotter, schedule reference, and how-to guide.
Microdosing is one of the most impactful tweaks you can make to your GLP-1 protocol — fewer side effects, smoother appetite, easier maintenance. But the math (and frequency planning) is annoying. We built this so you don't have to do it on a napkin.
Not affiliated with Novo Nordisk, Eli Lilly, or any pharmaceutical manufacturer. We don't sell GLP-1 medications, peptides, or pharmacy services. We're not a medical site — every page makes that clear.
All tools are free with no signup. We earn a small affiliate commission when readers purchase peptide vial cases through our partner site, VialCase. This pays for hosting and our time. We only recommend products we'd use ourselves.
We also operate GLP1Calculator.com (standard dose calculator + titration) and PeptideCase.com (storage guides + peptide blog).
