About This Tool
Where does the comparison data come from?
Every data point in the comparison matrix is pulled from our individual peptide profile pages. Each profile is reviewed by our research desk against primary sources: peer-reviewed journal articles, published clinical trial data, FDA/EMA guidance, and WADA listings. If you spot a discrepancy, use the contact page and we will correct it.
Can I compare brand names like Ozempic and Mounjaro?
Yes. Our data is organised by compound rather than brand, so Ozempic, Wegovy, and Rybelsus all map to semaglutide, while Mounjaro and Zepbound map to tirzepatide. If you select the active compound, the comparison covers every brand that uses it. Add tirzepatide and retatrutide alongside semaglutide for the full GLP-1 class picture.
How many peptides can I compare at once?
Up to four. We cap it at four because side-by-side readability degrades past that on standard screen widths. If you need a broader view, run two separate 4-way comparisons and share both links.
Can I share or bookmark a comparison?
Yes. Every comparison has a clean canonical URL like /compare/semaglutide-vs-tirzepatide-vs-retatrutide. Copy the address from your browser or use the share button at the top of any comparison page.
