Retatrutide Price: What 10 mg, 30 mg and 60 mg Cost, and What the Lot Reports Show
Research use only. Peptides supplied by Peptryn are sold strictly for in vitro and preclinical laboratory research. They are not approved by the FDA for human or veterinary use, and nothing here is medical advice, a dosing recommendation, or an instruction for self-administration. This page explains what Peptryn’s retatrutide vials cost and how to check any retatrutide listing.
Quick answer: Peptryn lists retatrutide as a lyophilized research vial in three sizes: 10 mg for $130.00 ($13.00 per mg), 30 mg for $225.00 ($7.50 per mg) and 60 mg for $320.00 ($5.33 per mg). MZ Biolabs lot reports are published for the 10 mg and 30 mg vials, and the 60 mg report is sent on request. Retatrutide is an investigational drug from Eli Lilly and is not FDA approved. Peptryn sells it only for laboratory research, to buyers who are 21 or older.
This page covers the price side: what each size costs, how that compares with four other shops, and what the lot reports add. To see how to buy it, read our where to buy retatrutide.
Key takeaways
- Price per mg falls with vial size: $13.00 at 10 mg, $7.50 at 30 mg and $5.33 at 60 mg. Quantity pricing takes 3%, 5% or 10% off.
- At 10 mg, three of the four other shops we checked list a lower price. At 30 mg and 60 mg, Peptryn is below the one shop that lists those sizes.
- The lab measured 13.65 mg in the 10 mg lot (+36.5%) and 36.71 mg in the 30 mg lot (+22.4%). Each figure is one lot from one lab.
- The 60 mg vial has no published lot report yet, and the 30 mg report has no endotoxin result.

Retatrutide price by vial size
| Size | Price | Price per mg | Lot report |
|---|---|---|---|
| 10 mg | $130.00 | $13.00 | Lot 2026-06-12, 99.62% purity, endotoxin negative |
| 30 mg | $225.00 | $7.50 | Lot 2026-08-31, 99.32% purity, identity confirmed |
| 60 mg | $320.00 | $5.33 | Not posted. Email the contact address with your order number |
Quantity pricing takes 3% off at 3 to 4 units, 5% off at 5 to 9 and 10% off at 10 or more. A 10 mg vial costs $126.10 at the first tier. Orders over $150 ship free from the USA with same-day dispatch, so a single 10 mg vial does not qualify on its own, and a 30 mg or 60 mg vial does.
The product page lists the full specification. Peptryn does not give dosing or use guidance for retatrutide.
How the price compares with other shops
These are listed prices from each shop’s own retatrutide product page on October 14, 2026. Shops change prices without notice, so treat the table as a snapshot.
| Shop | Size | Listed price | Price per mg |
|---|---|---|---|
| Peptryn | 10 mg | $130.00 | $13.00 |
| Peptryn | 30 mg | $225.00 | $7.50 |
| Peptryn | 60 mg | $320.00 | $5.33 |
| American Peptides | 10 mg | $105.00 | $10.50 |
| American Peptides | 20 mg | $200.00 | $10.00 |
| American Peptides | 30 mg | $240.00 | $8.00 |
| American Peptides | 60 mg | $400.00 | $6.67 |
| Neuropept Labs | 10 mg | $84.00 | $8.40 |
| Alpha Liquids | 10 mg | $120.00 | $12.00 |
| Advanced Research | 10 mg | $175.00 | $17.50 |
At 10 mg, Peptryn costs more than American Peptides, Neuropept Labs and Alpha Liquids, and less than Advanced Research. At 30 mg and 60 mg, Peptryn is lower than American Peptides, the only one of the four that lists those sizes. We did not audit any other shop’s testing. A lower price per mg says nothing about what is in the vial, and neither does a higher one.
What the lot reports add to the price
A price per mg uses the label amount. The lab’s reports list what it measured in each lot, and the two differ.
| Size | Label | Measured by the lab | Price per labeled mg | Price per measured mg |
|---|---|---|---|---|
| 10 mg (lot 2026-06-12) | 10 mg | 13.65 mg (+36.5%) | $13.00 | $9.52 |
| 30 mg (lot 2026-08-31) | 30 mg | 36.71 mg (+22.4%) | $7.50 | $6.13 |
The 10 mg figure was the highest of the 21 components in our September 2026 data report. The 30 mg lot is newer and came from the lab’s report directly. Both results come from one lot at one laboratory, without a stated assay uncertainty. The data report lists open questions, including whether a quantity figure is net peptide content or the gross contents of the vial, so use these as lot facts and not as a promise about your vial. A seller that publishes only label amounts gives you nothing to divide by.
What the two certificates show and leave out
| 10 mg lot | 30 mg lot | |
|---|---|---|
| Lot | 2026-06-12 | 2026-08-31 |
| Lab analysis date | 2026-06-19 | 2026-09-09 |
| HPLC purity | 99.62% (HPLC-UV-MS) | 99.32% (HPLC-UV-MS) |
| Identity | Expected 4,728.47 Da, measured 4,728.54 Da | Expected 4,728.47 Da, measured 4,728.52 Da |
| Endotoxin | Negative | No result on the report |
| Measured quantity | 13.65 mg | 36.71 mg |
| Where the records sit | MZ Biolabs’ own site, linked by a QR code on the certificate | MZ Biolabs’ own site, linked by a QR code on the certificate |
Each report covers one lot of one size. The 10 mg report does not describe the 30 mg or 60 mg vial. For the 60 mg size, ask for the report on file before you order. Our certificate guide shows how to read each line, and our third-party tested peptides guide sorts testing claims into five levels.
Five checks before you pay for any retatrutide vial
- Does the report cover your size? A report for a 10 mg lot says nothing about a 60 mg vial.
- Does the lot match? Compare the lot on your vial with the lot on the report, and check that the analysis date fits.
- Does the report confirm identity? Look for a mass near 4,728 Da, the monoisotopic mass the lab reports for retatrutide.
- Which results are listed? Purity, identity, endotoxin and quantity are separate tests. Each one missing is a gap.
- Is the report on the lab’s own site? A link or QR code to the lab’s record beats a PDF that sits only on the seller’s server.
Will retatrutide cost less once it is approved?
Nobody can say yet. Retatrutide is investigational and not FDA approved, and Eli Lilly has not announced a price. Lilly said on July 23, 2026 that it plans to file an approval application in the first quarter of 2027, a timeline our FDA approval status page covers. An approved version would be a prescription product dispensed under FDA labeling. A Peptryn vial is a laboratory material sold once, with no prescription attached, so the two prices do not count the same thing.
Why retatrutide price searches look so mixed
On October 13, 2026, the first page for “retatrutide price” held a shop homepage, a product-tag archive, a collection page, two clinic shops, one product page and two short articles, and only eight results appeared in total. Among the four shops we checked for this page, 10 mg listings ran from $84.00 to $175.00. Listings differ in size, documentation and what the seller says the product is for.
Peptryn’s vials are laboratory research materials. They are not clinic programs or drugs, and Peptryn does not offer them for human use.
Common questions
How much does retatrutide cost?
Peptryn lists retatrutide at $130.00 for 10 mg, $225.00 for 30 mg and $320.00 for 60 mg. That is $13.00, $7.50 and $5.33 per mg. Quantity pricing takes 3% off at 3 to 4 units, 5% at 5 to 9 and 10% at 10 or more.
How much is a vial of retatrutide?
It depends on the size. A 10 mg vial is $130.00, a 30 mg vial is $225.00 and a 60 mg vial is $320.00 on Peptryn. Other shops list 5 mg to 60 mg vials, so compare price per mg and the size of the vial, not only the price tag.
How much does a 10 mg retatrutide vial cost?
Peptryn lists the 10 mg vial at $130.00, which is $13.00 per mg. Lot 2026-06-12 reads 99.62% HPLC purity with a negative endotoxin result, and the lab measured 13.65 mg in that lot.
How much does a 30 mg retatrutide vial cost?
Peptryn lists the 30 mg vial at $225.00, which is $7.50 per mg. Lot 2026-08-31 reads 99.32% HPLC purity with identity confirmed by mass spectrometry, and the lab measured 36.71 mg. The report has no endotoxin result.
How much does a 60 mg retatrutide vial cost?
Peptryn lists the 60 mg vial at $320.00, which is $5.33 per mg. No report for this size is posted yet. Ask through the contact page with your order number and Peptryn sends the report on file.
Is Peptryn cheaper than other shops?
It depends on the size. On October 14, 2026, three of the four shops we checked listed a lower 10 mg price than Peptryn’s $130.00. At 30 mg and 60 mg, Peptryn was lower than American Peptides, the only one of those shops that lists them. Price per mg does not show testing quality.
Will retatrutide be cheaper once it is FDA approved?
No price has been announced, and retatrutide is not approved. An approved drug and a research vial are different products, so one price cannot predict the other.
Is retatrutide FDA approved?
No. Retatrutide is an investigational drug from Eli Lilly. A research vial sold by any shop is not an approved product.
