A 10mg research vial of retatrutide in the US can cost between $80 and $300, depending on purity testing, supplier reputation and bundle discounts. The 10mg vial costs $179.99 regular price and 127.49-149.99 on sale on the Lab Trust Peptides product page, which is in the mid-range. Retatrutide remains an investigational compound and these vials are sold for laboratory research use only, not for human use.This guide covers the factors that influence the retatrutide peptide price, how to compare suppliers fairly and what to look out for before ordering.
What Is Retatrutide, and Why Is It Sold as a Research Peptide?
Retatrutide, also known as LY3437943, is a synthetic peptide that activates three receptors: GIP, GLP-1, and glucagon. That triple action separates it from older compounds that target one or two of them. A phase 2 trial published in the New England Journal of Medicine in 2023 reported average weight reductions of up to 24.2 percent at 48 weeks in the highest dose group. Those results came from supervised clinical programs using trial material, not from research vials.
Because retatrutide is still investigational, it has no standard pharmacy price. Laboratories buy it as lyophilized powder, and that supply market is what this article covers.
What Is the Retatrutide10mg Price Right Now?
Most single 10mg vials sell for roughly $80 to $300, and many tested, documented options land between $130 and $200. One 2026 price guide puts 10mg vials at $80 to $200, while another suggests $150 to over $300 for a high purity research vial. Smaller marketplace listings appear lower, with one showing $88.42 for a 10mg vial, though testing details on those pages are often thin.

Why Do Retatrutide Prices Vary So Much Between Suppliers?
Four factors explain most of the gap between a $90 vial and a $250 vial.
Purity and Testing
Vendors that pay for HPLC and mass spectrometry on each batch carry higher costs, and that shows up in the price. A batch specific COA lets you see the reported purity instead of trusting a headline number.
Bundle and Quantity Discounts
Many sellers cut the per vial price when you buy several. Discounts of 10 to 15 percent are common, so compare the cost per milligram, not just the sticker price.
Shipping and Handling
Lyophilized powder is more stable than liquid, but cold chain shipping still adds cost. Competitor free shipping thresholds run around $250 on some sites, and about $200 on others.
Sourcing and Supplier Accountability
Most research grade retatrutide is synthesized by peptide manufacturers in China, then vialed, labeled, and resold by vendors worldwide. What you pay for is the vendor’s testing, labeling, and accountability.
How Can You Tell a Fair Price From a Suspicious One?
Use a simple five step check before ordering. First, ask for a batch specific COA and confirm the batch number matches your vial. Second, look for independent lab testing rather than in house claims. Third, calculate the price per milligram across at least three suppliers. Fourth, read the refund and returns policy. Fifth, be wary of any 10mg price far below the market range, since it often signals underdosed or unverified material. None of this makes a research vial suitable for human use.
Is the Cheapest Retatrutide Vial the Best Value?
Usually not. A $60 vial with no COA can cost more in the end if the results are unusable and the experiment must be repeated. For a laboratory, consistency matters more than saving $30. A tested vial at $130 to $150 is often better value than an untested one at half the price.
Conclusion
The retatrutide 10mg price typically falls between $80 and $300, and tested, documented vials usually sit between $130 and $200. Lab Trust Peptides lists its 10mg vial at $127.49 to $149.99 on sale, or $12.75 to $15.00 per milligram depending on bundle size. Compare cost per milligram, demand batch specific COAs, and treat unusually low prices with caution. These products are for laboratory research only.
