What this site is

RetaRadar compares online sellers that offer retatrutide as a research chemical, for laboratory research by qualified people. We record facts from the sellers’ own websites and from public sources, and we score them with a published checklist. We do not sell anything, we do not handle orders, and we do not test products ourselves.

Not medical advice

Nothing on this site is medical advice, a recommendation to use any substance, or a substitute for a licensed clinician. We do not publish doses, dosing schedules or instructions for use, and we do not list sellers that do (other than our disclosed sponsored partner, see below). If you are thinking about treatment for weight or diabetes, talk to a licensed doctor or pharmacist about FDA-approved options.

Legal status

Laws on buying, holding and using research chemicals differ by state and change over time. You are responsible for checking the law where you live. The FDA has warned the public about unapproved GLP-1 products sold online, including products labeled “for research use only”; see our retatrutide guide and our article on fake and compounded GLP-1 drugs.

Accuracy

Prices, stock, policies and lab reports change, often daily. Each review shows the date we checked it. We take care to record facts accurately, but we cannot guarantee that every detail is current or that a seller will act as its website says. Lab reports are as published by the seller; where we matched a report on the lab’s own site, the review says so.

Advertising

Our #1 position is a paid placement by our sponsored partner, LeoLab. Read the advertising disclosure.
