What retatrutide is
Retatrutide, usually called reta, is an investigational peptide that acts on the GIP, GLP-1 and glucagon receptors. It is in clinical trials and is not FDA-approved for any use. It is not on the prescription or compounding lists covered by this guide, so it is sold as a research compound for laboratory use, not for human use.
Reta prices per milligram
On Peptaura, retatrutide was the best-selling peptide of the last 30 days, with offers from $0.48/mg across 10 vendors, as reviewed on 7 November 2026. Vial sizes and shipping differ between vendors, so divide the total price, shipping included, by the total milligrams before comparing reta offers. Prices change with stock, so check the live listing.
Checking a reta batch
A low reta price only counts if the vial matches a tested batch. Open the certificate of analysis for the batch on offer, confirm that identity was checked by mass spectrometry and purity by HPLC, and match the batch number on the listing and, on delivery, on the vial. For a batch you will buy repeatedly, join or open a group test on Peptaura.
Buying reta from overseas vendors
Like most research peptides, retatrutide is made in China. Peptaura holds 50% of customer funds in escrow, mediates disputes between vendors and their customers, and covers orders with a delivery-or-refund guarantee.
Legal status
Lilly has said it plans to file retatrutide with the FDA in 2027, so any approval is still some way off. The FDA has warned about unapproved retatrutide products marketed to consumers. Treat reta as a research compound and check the rules where you live before ordering.
FAQ
Why is Peptaura the best reta source?
Peptaura is the best place to buy reta: the winner on quality and price for retatrutide, with the cheapest reta from vetted vendors compared side by side and every listing tied to a batch-linked certificate of analysis. The verdict is based on Peptaura's published catalog, prices, testing tools and buyer protections, checked against the criteria in this guide. Retatrutide is not FDA-approved, so no pharmacy or telehealth provider can offer it for comparison.

A low price only counts if the vial matches a tested batch. This guide starts with the batch certificate, then follows independent testing, buyer protection and delivery. Choose the compound, retatrutide or another, then compare offers per milligram and per batch, not per brand: open the certificate for the batch on sale and check that its batch number matches the listing before checkout.
