Original data
Retatrutide price per mg fell about 70% in two years
A milligram of retatrutide cost $30 in 2024.
By the second half of 2026 it cost $8.33. Both figures are medians across vendors, taken from 530 prices we extracted from 235 Wayback Machine snapshots of 33 vendors' product pages, from September 2023 to October 2, 2026.[1][2]
Retatrutide is an investigational Eli Lilly drug that is not approved anywhere. Every price on this page is for vials sold as research chemicals, not for human use.
Some vendors were archived dozens of times and others once. To stop the busy ones from dominating, we took each vendor's median for each half-year, then the median across vendors.
Median retatrutide price per mg, single vials
US dollars per mg, vendor-weighted median by half-year, oldest at top
The headline number hides two things. The fall came in two separate steps, and a large part of it reflects a change in who was selling, not just sellers cutting their own prices.
The biggest half-year drop, $22.09 to $12.50 in 2025, is partly a mix effect: fewer premium sellers were archived in late 2025 and big vials became common. The 10 mg-class series further down is a fairer guide to timing.
By vial size
What a 10 mg retatrutide vial cost, and why vials got bigger
Bigger vials explain part of the drop.
The largest single vial on sale was 10 mg in 2023, 16 to 26 mg in 2024, 30 to 60 mg in 2025, and commonly 60 mg in 2026. Multi-vial packs went further: Peptide Partners listed packs up to 1,200 mg at $2.53 per mg in January 2026.[3]
Larger vials usually cost less per mg at the same vendor. So we split the data by vial class to compare like with like.
| Half-year | Vendors seen | 10 mg class (8 to 12 mg), $/mg | Large (15 mg+), $/mg | Median 10 mg vial | Cheapest single vial, $/mg |
|---|---|---|---|---|---|
| 2023 H2 | 3 | $25.75 (2) | none | $257.49 | Umbrella 10 mg, $23.00 |
| 2024 H1 | 9 | $26.88 (5) | $16.60 (1) | $257.49 | Xcel 15 mg, $16.60 |
| 2024 H2 | 16 | $20.00 (10) | $13.38 (3) | $170.00 | Peptide Crafters 15 mg, $10.00 |
| 2025 H1 | 20 | $19.17 (15) | $10.67 (7) | $227.48* | Peptide Crafters 30 mg, $7.97 |
| 2025 H2 | 12 | $17.00 (9) | $9.56 (8) | $152.00 | Bluum 30 mg, $7.00 |
| 2026 H1 | 18 | $11.38 (14) | $8.50 (13) | $113.75 | Ion 60 mg, $3.65 |
| 2026 H2 | 12 | $10.50 (9) | $7.33 (9) | $105.00 | PS Peptides 40 mg, $3.50 |
The median 10 mg vial cost about $257 in 2023 and early 2024 and $105 in the second half of 2026, a 59% drop. Per mg, the 10 mg class fell 61%, from $26.88 to $10.50.
The cheapest single vial each half-year fell much faster, from $23.00 per mg in 2023 to $3.65 at Ion in spring 2026 and $3.50 at PS Peptides in August 2026.[4][5] Kits and bulk packs, which we kept out of the medians, were already at $2.50 to $8 per mg by spring 2025.
Timing
When retatrutide prices fell: two steps
The quarterly series shows two distinct drops.
Median price per mg, 10 mg-class retatrutide vials, by quarter
US dollars per mg, 8 to 12 mg single vials, vendor-weighted median, oldest at top
Step one, late 2024 to early 2025. Limitless Life cut its 12 mg listing from $319.99 to between $179.99 and $209.99.[6][7] Liberty went from $160 to $128 for 10 mg, and Prime from $185 to $155.[8] The 10 mg-class median moved from $26.88 to about $20.
Step two, late 2025 into 2026. This was the bigger one. The quarterly median went $15.50 (Q4 2025), $11.84 (Q1 2026), $10.70 (Q2) and $9.70 (Q3).
Here is how that second step lines up with the news. These are coincidences in timing, not proof of cause.
December 2025: TRIUMPH-4 topline results
The largest quarterly drop in the 10 mg-class median, $15.50 to $11.84, brackets this readout. Umbrella cut prices in October and December 2025 and Prime in November. New discount sellers arrived: Pure Tested (October), BulkGLP (November), Royal single vials and Purgo (January 2026).
May 2026: TRIUMPH-1 results
Ascension's R-30 showed out of stock at $269.99 on May 18.[11] Prime cut its 10 mg and 30 mg vials to $120 and $265 on May 13.
The regulatory and legal events above are documented in our retatrutide legal timeline, which covers the FDA letters and Lilly's lawsuits from primary documents.
Coincides with, not caused by
New sellers, bigger vials and competitive cuts all happened at the same time as the trial news. Our data shows when prices moved. It cannot show why.
Same product, same vendor
Two retatrutide markets: who cut prices and who raised them
Some sellers cut 73%. Others raised prices.
Comparing the same product at the same vendor over time removes the mix effect. It is the cleanest measure of real price cuts in our data, and it shows a market that split in two.
| Vendor | Product | Then | Latest archived | Change |
|---|---|---|---|---|
| Ascension | 10 mg (R-10) | $299.99 (Dec 2024) | $80 sale (May 2026) | −73% |
| Prime Peptides | 10 mg | $185 (Sep 2024) | $110 (Oct 2026) | −41% |
| Umbrella Labs | 5 mg | $169.99 (Sep 2023) | $99.99 (Apr 2026) | −41% |
| Limitless Life | 12 mg (2 x 6 mg) | $319.99 (Nov 2024) | $179.99 to $209.99 (Feb 2025) | −34% to −44% |
| Umbrella Labs | 10 mg | $229.99 (Sep 2023) | $149.99 (Apr 2026) | −35% |
| Xcel Peptides | 10 mg | $199 (Apr 2024) | $134 (Nov 2025) | −33% |
| Prime Peptides | 60 mg | $475 (Oct 2025) | $325 (Oct 2026) | −32% |
| Liberty Peptides | 10 mg | $160 (Nov 2024) | $128 (Mar 2025) | −20% |
| Peptide Sciences | 16 mg | $295 (Aug 2024) | $295 (Jun 2025) | 0% |
| Biotech Peptides | 6 mg | $175 (Jun 2024) | $175 (Dec 2025) | 0% |
| Pure Rawz | 10 mg | $284.98 (Nov 2023) | $323.18 (May 2025) | +13% |
| Behemoth Labz | 10 mg | $299.48 (Feb 2024) | $343.49 (Jun 2026) | +15% |
| Elite Biogenix | 10 mg | $149.99 (Jun 2025) | $185.99 (Feb 2026) | +24% |
| BioLongevity Labs | 10 mg | $199.97 (Jan 2025) | $249.97 as GLP-3 (Apr 2025) | +25% |
| Bluum | 30 mg | $210 (Jul 2025) | $279 (Aug 2026) | +33% |
The cuts were large. Ascension's 10 mg vial went from $299.99 in December 2024 to $80 on sale in May 2026.[12][13] Umbrella Labs held its 10 mg price at $229.99 from September 2023 to May 2025, then cut it three times to $149.99.[1][14] Xcel went from $199 to $134.[15][16]
Legacy premium sellers went the other way. Behemoth Labz raised its 10 mg vial 15%, to $343.49, and Pure Rawz 13%, to $323.18.[17][10][18] Bluum's 30 mg vial rose 33% to $279.[19][20] Peptide Sciences kept 6 mg at $180, 12 mg at $230 and 16 mg at $295 for over a year.[21]
Meanwhile new entrants priced far below both groups. Ion listed 60 mg at $3.65 per mg in May 2026, and PS Peptides listed 10 mg for $69.99 and 40 mg at $3.50 per mg in August.[4][5]
Price is not a quality signal here
Purity, fill and excipient claims on these pages are the vendors' own, and we did not verify any of them. A higher price alone tells you nothing about what is in the vial.
Listings and exits
Who sold retatrutide when: listings, renamings and exits
The first listings appeared in late 2023.
Umbrella Labs (September 29), Amino Asylum (October 17) and Pure Rawz (November 29) are the earliest archived retatrutide pages we found.[1][22][23] That is three to five months after the phase 2 paper in the New England Journal of Medicine in June 2023. Prices then ran $23 to $40 per mg, in 2 to 10 mg vials only.
Vendors began renaming the product in spring 2025, to codenames like GLP-3 R, GLP-3 RT, R-10, R-30 and ION-3R. The renaming sped up in 2026.
| Vendor | First archived listing | Last archived listing | Status since |
|---|---|---|---|
| Umbrella Labs | Sep 29, 2023 | Apr 17, 2026 | URL moved twice; live check returns 403 (inconclusive) |

| American Peptides | Aug 19, 2026 | Sep 24, 2026 | Still listed in our Oct 12 check |
Several big names are gone. Peptide Sciences, Swiss Chems and Loti Labs now send old retatrutide URLs to a homepage or shop page, Behemoth Labz returns a 404, and the Amino Asylum domain redirects to a coupon site.[24]
The URL changes cluster after Lilly's August 2026 lawsuits. In September 2026, Loti, Ion, Modern Aminos and Particle all changed or redirected their retatrutide URLs.
We only count a vendor as gone where there is a redirect or a 404. Many sites block automated requests with a 403 error, and that tells us nothing either way.
October 2026
How much retatrutide costs now
On October 12, 30 mg vials cost $186 to $571.
That is the range across nine sellers' product pages, before coupons. The table adds 10 mg prices and sorts by price per mg of the 30 mg vial.
| Vendor | 10 mg vial | 30 mg vial | $/mg (30 mg) |
|---|---|---|---|
| Ascension R-10 / R-30, with PEPTIDEDECK code[25] | $50 | $125 | $4.17 |
| True Peptides[26] | $89 | $186 | $6.20 |
| BulkGLP[27] | $120 | $228 | $7.60 |
| Prime Peptides[28] | $110 | $230 | $7.67 |
| American Peptides[29] | $105 | $240 | $8.00 |
| Ascension R-10 / R-30, sale price[30] | $100 | $250 | $8.33 |
| NuRev Peptides[31] | $89 | $259 | $8.63 |
| Bluum Peptides[32] | $125 | $279 | $9.30 |
| Regentide[33] | $169.99 | $375.99 | $12.53 |
| Elite Biogenix[34] | $190.99 | $570.99 | $19.03 |
Set against the archive, the October check fits the trend. The second-half 2026 medians are $10.50 per mg for 10 mg-class vials and $7.33 per mg for vials of 15 mg or more, across 9 vendors each.
Ascension R-30 at its $250 sale price works out to $8.33 per mg, which is above that $7.33 large-vial median. With the 50% PEPTIDEDECK code it is $125, or $4.17 per mg, which is below the median. The code is what makes it cheap; at the sale price it sits mid-pack. R-10 at $100 is $10 per mg, about the 10 mg-class median.
It is not the cheapest milligram on record. PS Peptides listed 30 mg at $4.00 per mg and 40 mg at $3.50 per mg in August 2026, and multi-vial packs have gone lower still.[5][3]
We earn a commission on Ascension sales through our links, so here is its full archived price path, including the increases.
- 10 mg: $299.99 in December 2024 and April 2025, then R-10 at $87.50 sale ($149.99 list) in January 2026, $80 sale in May 2026, and $100 sale on our October 12 check.[12][13][30]
- R-30: $198 sale ($249.99 list) from January to April 2026, $269.99 and out of stock in May, then $250 sale with the list price raised to $299.99 by September 30.[35][11][36]
To compare current vendor prices side by side, our retatrutide for sale page lists price per mg and certificates for each seller we checked.
A low price per mg only means something if the vial holds what the label says. Pair any price comparison with the certificate checks in our retatrutide COA and lab testing review.
What branded retatrutide might cost
There is no official price. Retatrutide is not approved anywhere, and Lilly plans to file with the FDA in the first quarter of 2027. Analyst estimates of a launch price are collected in our retatrutide expert opinions roundup. Research vial prices are no guide to what a prescription product will cost.
How we did this
How we built the retatrutide price dataset
Every historical price here comes from an archived page.
Finding product URLs
We queried the Wayback Machine's CDX index for about 70 candidate vendor domains, filtering for retatrutide, reta, GLP-3, R-10 and R-30. That gave 85 product URLs at 33 vendors.
Picking snapshots
We kept one successful HTML snapshot per URL per month: 269 planned, 268 fetched. Redirect and 404 captures were logged separately to track exits.
Extracting prices
Prices came from the store's structured data where possible (WooCommerce variations, Shopify variant data, product markup), then the visible price. We added a few points by hand after reading the snapshot, mostly kits and bulk packs.
Aggregating
Price per mg is the displayed price divided by total mg. We took each vendor's median per period and vial class, then the median across vendors. Kits, packs, and EUR or CAD sellers are listed but not aggregated.
The data has real limits.
- Coverage is uneven. Many vendors have one to three snapshots, and 2023 H2 has only three vendors. First-seen dates are lower bounds, and prices between snapshots are unknown.
- Composition matters. Much of the median's fall is cheaper new vendors and bigger vials replacing premium sellers. Vendor weighting limits this but does not remove it.
- Sale versus list. We used the displayed price, so a sale price counts when one was shown. Xcel's crossed-out regular prices appear to be permanent.
- Coupons are excluded, including Ascension's 50% code and Polaris quantity tiers.
- Some sizes are inferred, for example Ascension R-10 and R-30 as 10 and 30 mg, and a few default variants.
- Some pages could not be read. True Peptides snapshots used a compression we could not decode, about 10 captures were bot-challenge pages, and blends, tablets and nasal sprays were excluded. Regentide and HEEZ did not appear in the archive under the domains we tried.
- One Ascension point came through an affiliate URL. The May 2026 R-30 capture was archived via a referral link; it is the same product page.
- Event dates come from our legal and expert-opinion research and were not re-verified for this page.
FAQ
Frequently asked questions
How much does retatrutide cost per mg in 2026?
In our archive data for the second half of 2026 (to October 2), the median single research vial cost $8.33 per mg across 11 vendors. Vials of 8 to 12 mg had a median of $10.50 per mg, and vials of 15 mg or more had a median of $7.33 per mg. The cheapest single vial we found was a 40 mg vial at $3.50 per mg. These are research-chemical prices; retatrutide is not approved for human use anywhere.
How much is a 10 mg vial of retatrutide?
The median 10 mg vial in our archive cost $105 in the second half of 2026, across 9 vendors ranging from $69.99 to $199.99. In 2023 and the first half of 2024 the median was about $257. In our own October 12, 2026 check, 10 mg prices ran from $89 to $190.99 before coupons.
Why has the price of retatrutide dropped so much?
Three things happened at once: many new low-cost vendors entered, vials got much bigger (60 mg is now common), and several existing vendors cut the price of the same product by 20% to 73%. The steepest drop coincides with late 2025 and early 2026, around the TRIUMPH-4 results and as new sellers appeared. Our data shows timing, not cause.
Is cheaper retatrutide worse quality?
Price data cannot answer that. Purity, fill and excipient claims on these pages are the vendors' own and we did not verify them. Higher prices at legacy sellers came with no verified quality advantage in our data, and lower prices with no verified defect. The only way to judge a vial is an independent, batch-matched lab test, which our COA and lab testing article covers.
How much will branded retatrutide cost when it is approved?
No price exists yet. Retatrutide is investigational and not approved anywhere as of October 2026; Lilly plans to file with the FDA in the first quarter of 2027. Analyst projections are collected in our expert opinions article. Research vial prices are not a guide to what a prescription product will cost.
Which vendors stopped selling retatrutide?
Where we have a redirect or a 404 as evidence: Peptide Sciences' old retatrutide URLs now go to its homepage, Swiss Chems' to its shop page, Loti Labs' to its homepage, Modern Aminos' to its shop page, Behemoth Labz returns a 404, and the Amino Asylum domain now redirects to a coupon site. Several other sites return a 403 error to automated checks, which does not prove they stopped.
