How Much Does Retatrutide Peptide Cost for a Research Lab in 2026?

Retatrutide peptide costs $149.99 for one 10mg vial at Lab Trust Peptides, $134.99 per vial when you order three or four, and $127.49 per vial when you order five or more. Add roughly $11 to $13 for a bottle of bacteriostatic water and you have the practical cost of getting one vial ready for laboratory work. The compound is sold for research use only, and everything below comes from the store’s own product page.

What Is the Basic Retatrutide Peptide Cost per Vial?

The listing at labtrustpeptides.com/product/retatrutide/ shows a regular price of $179.99 and a current price of $149.99. That is a $30 reduction, or about 17 percent. The page calls it a limited batch release available only while stock lasts, which is a polite way of saying the number may not stay the same.

One vial holds 10mg of lyophilized peptide in a sterile glass container. Free cold-chain shipping is listed for the USA, so the price you see is close to the price you pay at the door.

How Does the Cost Change When You Order More?

The page has a small discount table. Buying one or two vials costs the full $149.99 each. Three or four vials bring the price down 10 percent to $134.99 each. Five or more bring it down 15 percent to $127.49 each.

In totals, that is $299.98 for two vials, $404.97 for three, $539.96 for four and $637.45 for five. The jump from two to three is the most interesting one, because the third vial adds only $104.99 to the bill.

What Is the Cost per Milligram?

Since the vial is 10mg, the arithmetic is simple. You pay about $15.00 per milligram at the single-vial price, $13.50 at three or four vials, and $12.75 at five or more. Per-milligram cost is the fairest way to compare retatrutide against any other seller, because it strips out packaging choices and looks only at the amount of peptide you receive.

What Does the Cost Include?

According to the page, each peptide ships with a Certificate of Analysis containing qualitative and quantitative data. The store also says testing across its range can include LCMS screening, heavy metals analysis, endotoxin testing and sterility verification, with randomized full-panel testing by independent laboratories, and it states 99 percent purity. Every order also comes with a free 52-page eBook, Beginners Guide to Peptides, which the store values at $29.

Those are the seller’s claims. A careful buyer reads the actual COA for the batch received and checks that it names a laboratory, carries a batch number and matches the vial.

What Costs Are Not Included?

The vial is only the peptide. To reconstitute it, laboratories use bacteriostatic water or another suitable solvent, which the store sells for about $11.04 to $12.99 for 10ml. Storage is the second extra. The page says lyophilized powder should be kept at minus 20 degrees Celsius, and reconstituted material at 2 to 8 degrees Celsius, protected from light, moisture and heat. If you lack suitable freezer space, that becomes a real cost.

Payment adds a small unknown. The store accepts bank transfer, crypto and credit card, and the page lists no surcharge, but your own bank or network may add fees.

What Is the Realistic Cost for One Vial?

Add the water and a single vial comes to $161.03 to $162.98. For a three-vial order with one bottle per vial, each vial lands at roughly $146 to $148. For five vials, each lands at roughly $138.50 to $140.50. These are the numbers worth putting in a budget spreadsheet.

Is There Any Way to Lower the Cost Further?

The site shows a pop-up offering 10 percent off a first order for joining its newsletter. The product page does not say whether the code stacks with the quantity discount, so test it at checkout and do not assume it works. The most reliable way to lower the cost is to choose the right quantity for your project and place a single consolidated order.

What Does the Refund Policy Mean for the Cost?

All sales are final, and standard returns are not accepted. The one stated exception is purity: if a product comes back below 99 percent, the page says the store will provide a full refund with no questions asked. Using that promise requires a way to test purity, so a careful lab either budgets for an independent test or accepts that the guarantee may be hard to claim.

How Does Regulation Shape the Cost?

Retatrutide is not FDA approved, and no official retail price exists from the manufacturer. The product page states the vial is for research use only and is not for human consumption, medical, veterinary or diagnostic use, and that research findings are preliminary and do not imply safety or efficacy. The cost on the page is the cost of a laboratory chemical, not a medicine.

What Is the Short Answer?

For a research lab, retatrutide peptide cost about $150 for one vial, $135 each for three or four, and $127 each for five or more, plus a small amount for solvent and the cost of correct storage. Confirm the live price, read the batch documentation and plan the full budget before you order.
