Retatrutide is a single-molecule triple agonist peptide that acts on the GIP, GLP-1, and glucagon receptors, which places it in the same GLP-1 family as semaglutide and tirzepatide. Vendors also call it Reta, tri-agonist, or by the development code LY3437943. It is listed strictly as a research-use-only chemical, sold as a lyophilized powder measured in milligrams per vial. Because it reached the research market more recently, fewer vendors carry it and the price spread runs wide.
With a thin vendor field, one outlier can skew the picture, so the table above reduces every listing to landed cost per mg, not sticker price. Vials cluster in the low milligram range, so comparing a 5 mg vial to a 10 mg one means dividing price plus shipping by total milligrams.
Shoppers routinely weigh it against semaglutide and tirzepatide. Check the coupons page for a code that can reorder them.
